Abstract
OBJECTIVE To understand patients' motivations for pursuing treatment, to appreciate what information patients seek and to explore potential factors affecting decision making in adults considering, undergoing or who have had orthodontic treatment in the private sector. DESIGN Cross-sectional questionnaire study. SETTING Online questionnaire. PARTICIPANTS A total of 209 (83% women, 16% men, 1% preferred not to say) completed responses were received. METHODS Once piloted, the final survey was made available online to adults in the United Kingdom (UK) and Republic of Ireland (RoI) who were either considering having orthodontic treatment, currently undergoing treatment or had recently completed treatment in the private sector. RESULTS The most commonly selected motivating factor was to 'improve the appearance of my teeth' (82%). The information sought related predominantly to treatment duration (64%), potential end results (56%), types of appliances that were available (55%) and cost (52%). The two most commonly reported social factors that had influenced participants to consider treatment were 'seeing myself on social media' (31%) and 'it is more socially acceptable to have braces' (31%). CONCLUSION While this area remains relatively underexplored in the literature, it is crucial to develop a comprehensive understanding due to the increasing number of adults seeking orthodontic treatment. This study not only reinforces the existing knowledge regarding adults seeking orthodontic treatment, such as the predominant role of aesthetics as a motivating factor, but also introduces some novel insights. Specifically, we highlight the influence of social factors on decision-making processes and the importance of effectively communicating the duration of treatment to patients.

Long-term profile attractiveness of patients with Class I and II malocclusion treated with and without extractions: A 35-year follow-up. Am J Orthod Dentofacial Orthop 2024; 165:513-519. [PMID: 38231168 DOI: 10.1016/j.ajodo.2023.11.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 11/01/2023] [Accepted: 11/01/2023] [Indexed: 01/18/2024]
Abstract
INTRODUCTION The objective of this study was to compare the profile attractiveness in subjects treated with and without extractions after the long-term 35-year follow-up, according to laypeople, dentists, and orthodontists. METHODS A total of 40 patients with Class I and II malocclusion were divided into 2 groups, according to the treatment protocol: extraction (E) group, extractions of 4 premolars (n = 24), with mean pretreatment (T1), posttreatment (T2), and long-term posttreatment (T3) ages of 13.13, 15.50 and 49.56 years, respectively. The mean treatment time (T2 - T1) was 2.37 years, and the long-term follow-up (T3 - T2) was 34.19. Nonextraction (NE) group (n = 16), with mean ages at T1, T2, and T3 of 13.21, 15.07, and 50.32 years, respectively. The mean (T2 - T1) was 1.86 years, and the (T3 - T2) was 35.25 years. Lateral cephalograms were used to perform profile facial silhouettes, and an online evaluation was performed by 72 laypeople, 63 dentists, and 65 orthodontists, rating the attractiveness from 1 (least attractive) to 10 (most attractive). The intragroup comparison was performed with the repeated measures analysis of variance and Tukey tests. Intergroup comparison was performed with t tests, 1-way analysis of variance, and Tukey tests. RESULTS The E group had a longer treatment time than that of the NE group. In the pretreatment, posttreatment, and long-term posttreatment stages, the E and NE groups showed similar profile attractiveness. Laypersons and dentists were more critical than orthodontists. CONCLUSIONS At long-term posttreatment follow-up, profile attractiveness was similar in patients treated with and without extractions.

Abstract
BACKGROUND The physical appearance of an individual plays a primary role as it influences the opinion of the viewer. For this reason, orthodontic therapy to improve perceived aesthetics is in high demand among patients. This factor, combined with the increase in the number of non-invasive facial aesthetic treatments, has led to the need to understand potential risk factors in the application of medical devices to the perioral skin in patients with fixed orthodontic appliances. The aim of this study was to evaluate in vitro heating of the orthodontic bracket following electromagnetic fields and negative pressure (V-EMF) used as an anti-aging treatment. METHODS Two different types of titanium alloy wires, one made of "beta-Titanium" alloy and the other "Ni-Ti" (DW Lingual Systems GmbH-Bad Essen-Germany) were used. The orthodontic wires and brackets mounted on a resin mouth were covered with porcine muscle tissue, then subjected to anti-aging therapy with a Bi-one LifeTouchTherapy medical device (Expo Italia Srl-Florence-Italy) which generates a combination of vacuum and electromagnetic fields (V-EMF) already adopted for antiaging therapy. During administration of the therapy, the orthodontic brackets and porcine tissue were thermally monitored using a Wavetek Materman TMD90 thermal probe (Willtek Communications GmbH-Germany). In total 20 orthodontic mouths were used, 10 with Beta Titanium wires and 10 with Nickel Titanium wires. RESULTS A temperature increase of about 1°C was recorded in each group. The outcome of the present research shows that the absolute temperatures measured on orthodontic appliances, which, despite having a slightly different curve, both show an increase in temperature of 1.1°C at the end of the session, thus falling well within the safety range of 2°C as specified by the standard CENELEC EN 45502-1. Therefore, V-EMF therapy can be considered safe for the entire dental system and for metal prostheses, which tend to heat up at most as much as biological tissue (+0.9°C/1.1°C vs. 1.1°C/1.1°C). CONCLUSION In conclusion, anti-aging therapy with V-EMF causes a thermal increase on orthodontic brackets that is not harmful to pulp health.

Abstract
PURPOSE This study aimed to verify whether there is a difference in biomarker levels in the gingival crevicular fluid between premenopausal and postmenopausal women undergoing orthodontic treatment. METHODS As eligibility criteria, prospective or retrospective observational studies evaluating women undergoing orthodontic treatment (P), comparing postmenopausal (E) and premenopausal (C) women, and analyzing differences in gingival crevicular fluid biomarkers (O) were included. An electronic search was conducted in seven databases (PubMed, Scopus, Web of Science, LILACS, The Cochrane Library, Embase, and EBSCO: Dentistry & Oral Science) and one grey literature source (Google Scholar). All databases were searched from September 2022 to March 2023. After duplicate exclusion and data extraction, the Newcastle-Ottawa scale was applied to assess the quality and risk of bias, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool was used to verify the certainty of evidence. RESULTS Three case-control studies that analyzed receptor activator of nuclear factor kappa‑B ligand (RANKL), osteopontin (OPN), and interleukin (IL)-17A levels were included. One study reported a significant difference for RANKL and another for OPN levels. A third study reported that there was a higher expression of IL17‑A in the postmenopausal group. However, the small number of articles limits our systematic review. The heterogeneity and imprecision in the study results cast doubt on the findings' internal validity. CONCLUSION The studies reported alterations in biomarker levels but differed in their conclusions. Therefore, further studies must include other types of bone and inflammatory biomarkers in female patients who are pre- or postmenopausal and undergoing orthodontic treatment. REGISTRATION The review was registered at the Open Science Framework ( https://doi.org/10.17605/OSF.IO/Q9YZ8 ).

Abstract
This is the second of two papers outlining the orthodontic management of patients with cleft lip and palate. The first paper reviewed orthodontic input into children with cleft lip and palate from birth to the late mixed dentition before definitive orthodontics. In this second paper, I will discuss tooth management across the grafted cleft site and its impact on the bone graft itself. I will also discuss the some of the challenges of the adult patient returning to the service.

Abstract
Background During orthodontic treatment, teeth with brackets may sometimes be restored with different restorative materials. In this case, the content of the orthodontic adhesive selected for bracket bonding may also be important. Aim This study compared the bond strength of metal orthodontic brackets adhered to different resin composite and glass ionomer cement (GIC) restoration surfaces with glass ionomer-based and resin-based orthodontic adhesives to determine the best orthodontic adhesive for use in restored teeth. Material and Methods This study prepared 80 discs. Four material groups of 20 discs were created: reinforced high-viscosity GIC, high-viscosity GIC, flowable bulk-fill resin composite, and nanohybrid resin composite. Specimens in each material group were divided into two subgroups that differed in the orthodontic adhesive used to bond the brackets to the prepared specimens. After 24 hours, the specimens were shear bond strength (SBS) tested at 1 mm/min using a universal tester. Results The SBS of glass ionomer-based orthodontic adhesive differed significantly between metal brackets adhered to different bases (P < 0.001). The highest SBSs were observed between metal brackets and high-viscosity glass ionomer restorations (6.79 ± 2.38). The highest SBSs observed with a resin-based orthodontic adhesive were between metal brackets adhered to nanohybrid resin composite restorations (8.84 ± 2.10; P = 0.030). Conclusions Glass ionomer-based orthodontic adhesive provided safer bond strength and demineralization prevention when applying metal brackets to teeth with glass ionomer restorations.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2023; 124:101285. [PMID: 36087916 DOI: 10.1016/j.jormas.2022.09.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 09/05/2022] [Accepted: 09/06/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND Temporomandibular disorder (TMD) symptoms were found to be common in the patients with maxillofacial deformities. The mandibular structure was in relation with the stress within temporomandibular joint (TMJ). However, the current studies on the TMJ stresses in the patients with different maxillofacial deformities are not comprehensive enough. PURPOSE The aim of this study was to investigate the compression and morphology of the TMJ in the patients with different maxillofacial deformities under central occlusion. METHODS 24 patients and 10 asymptomatic individuals were included in this study and divided into patient groups and control group. The 3D models were reconstructed. Muscle forces and boundary conditions corresponding to the central occlusion were applied. Nine morphological parameters of mandible were evaluated. RESULTS The minimum principal stresses in the articular disc and condyle were significantly greater than those of the control group (P<0.05). For the articular disc, the compression on the non-deviation side was greater than those on the deviation side in patients with asymmetrical mandibles. There was difference between both sides in the mandibular prognathism and retrusion groups. The joint space of patients was significantly lower than that of the control group (P<0.05). CONCLUSIONS Maxillofacial deformities might change the condylar position within the articular fossa, which decreased the joint space and increased the compression within TMJ. The patients with asymmetry mandible suffered greater pressure within TMJ on the non-deviation side. The bilaterally over-developed and under-developed mandible in patients might also increase the compression within TMJ.

Abstract
Management of the growing adult orthodontic patient population must contend with challenges particular to orthodontic treatment in adults. These include a limited rate of tooth movement, increased incidence of periodontal complications, higher risk of iatrogenic root resorption and pulp devitalisation, resorbed edentulous ridges, and lack of growth potential. The field of regenerative dentistry has evolved numerous methods of manipulating cellular and molecular processes to rebuild functional oral and dental tissues, and research continues to advance our understanding of stem cells, signalling factors that stimulate repair and extracellular scaffold interactions for the purposes of tissue engineering. We discuss recent findings in the literature to synthesise our understanding of current and prospective approaches based on biological repair that have the potential to improve orthodontic treatment outcomes in adult patients. Methods such as mesenchymal stem cell transplantation, biomimetic scaffold manipulation, and growth factor control may be employed to overcome the challenges described above, thereby reducing adverse sequelae and improving orthodontic treatment outcomes in adult patients. The overarching goal of such research is to eventually translate these regenerative techniques into clinical practice, and establish a new gold standard of safe, effective, autologous therapies.

Abstract
Purpose The article is aimed at improving the understanding of the sociocultural profile of adult orthodontic patients and their expectations. In particular, it addresses three main aspects: the motivation and needs that underpin the decision to start orthodontic treatment, how it influences the patients' daily life, and the different oral hygiene demands. Materials and Methods An online survey was completed by 276 patients undergoing orthodontic treatment with different techniques. The questions asked concerned gender, age, type of appliance, any previous orthodontic treatments, type of any previous retainers, reasons for therapy, satisfaction, pain, problems in eating, daily number of teeth brushings and flossings before and during the treatment, perception of cost, sensation of visibility of the appliance, and if they would recommend orthodontic treatment. Results A significant role within our sample is played by gender; 87.94% consisted of female patients out of which 72.57% wanted to improve their aesthetics, while only 54.84% of male patients cited the same reason. Invisible aligners were preferred by 67.70% of the patients due to them being considered the least painful, causing the fewest problems with eating, and the least visible. Metal braces were perceived as the less expensive treatment. Over a third of the patients (33.85%) had previously undergone orthodontic treatment, among them 54.05% wore a mobile retainer, 31.08% a fixed one, and 14.86% both. Daily tooth brushing and flossing increased during therapy with clear aligners by 48.94% and 126.39%, respectively. Conclusions The greatest demand for orthodontic treatments comes from women, as they pay more attention to aesthetics, which makes the clear aligners the most common choice. The relapse after orthodontic treatment seems to cause a higher demand for retreatment, and oral hygiene habits significantly improve during orthodontic treatment, especially with the clear aligners.

Abstract
Our Objective was to treat a patient having proclined, protruded teeth along with a Class II Skeletal malocclusion. 0.022 × 0.028 inch MBT Brackets were placed, and leveling alignment was commenced. Individual canine retraction was carried out in both arches, followed by retraction of the incisors in the upper arch with a Burrstone's T Loop. E2Z Forsus fatigue resistance appliance was given for the correction of Class II malocclusion. Proclination, protrusion, and crowding were corrected along with Class II Skeletal base. Individual canine retraction along with frictionless mechanics and noncompliant functional correction has sufficient potential to prevent anchor loss and correct a Class II skeletal base.

Abstract
Aims Orthodontic care and its effectiveness have increasingly become the focus of political and public attention in the recent past. Therefore, this multicenter cohort study aimed to report about the effectiveness of orthodontic treatments in Germany and to identify potential influencing factors. Methods A total of 586 patients from seven German study centers were screened for this cohort study, of which 361 patients were recruited at the end of their orthodontic treatment. Of these, 26 patients had missing study models and/or missing treatment information. Thus, 335 participants were included. The severity of malocclusion was rated using the Peer Assessment Rating (PAR) Index at baseline (T0) retrospectively and—prospectively—after the retention period (T1). Practitioner-, treatment- and patient-related information were analyzed in order to detect potential predictive factors for treatment effectiveness. Results Study participants (202 female and 133 male) were on average 14.8 (standard deviation [SD] ± 6.1) years old at start of active treatment. Average PAR score at T0 was 25.96 (SD ± 10.75) and mean posttreatment PAR score was 3.67 (SD ± 2.98) at T1. An average decrease of total PAR score by 22.30 points (SD ± 10.73) or 83.54% (SD ± 14.58; p < 0.001) was detected. Furthermore, 164 treatments (49.1%) were categorized as ‘greatly improved’ but only 3 treatments (0.9%) as ‘worse or no different’; 81.5% of all cases finished with a high-quality treatment outcome (≤5 PAR points at T1). Logistic regression analyses detected staff experience as a significant predictive factor for high-quality results (odds ratio 1.27, p = 0.001, 95% confidence interval 1.11–1.46). Conclusion The improvement rate among this selected German cohort indicated an overall very good standard of orthodontic treatment. Staff experience proved to be a predictive factor for high-quality results.

Stability of single-jaw vs two-jaw surgery following the correction of skeletal class III malocclusion: A systematic review and meta-analysis. Orthod Craniofac Res 2020; 24:314-327. [PMID: 33305502 DOI: 10.1111/ocr.12456] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 11/18/2020] [Accepted: 12/03/2020] [Indexed: 11/26/2022]
Abstract
This review aims to compare the stability of sagittal skeletal and overjet anteroposterior correction of skeletal class III malocclusion in single-jaw and two-jaw orthognathic procedures. An unrestricted comprehensive electronic search was undertaken on Embase, Cochrane's CENTRAL, Web of Science, Medline, Scopus and LILACs databases up to October 2020. The bibliographies of relevant studies, ongoing, unpublished and grey literature were screened. Two independent reviewers performed study selection, bias assessment and data extraction; a third reviewer mediated inconsistencies. Randomized clinical trials, prospective cohort, retrospective cohort and series with a minimum of 1 year follow-up were eligible for inclusion. Additional subgroup analyses were undertaken. The generated effects were scored using the GRADE approach. Nine articles met the inclusion criteria and eight studies were subsequently analysed quantitatively. No significant difference in sagittal stability at the ANB angle, A-point or B-point on a short-term was detected. However, a statistically significant difference, indicating a greater short-term relapse in overjet with mandibular setbacks alone, was found (MD: -0.40 mm; 95% CI -0.77 to -0.04; I2 : 0%; P = .03). Long-term follow-up (≥5 years) revealed a statistically non-significant difference in stability of sagittal skeletal and overjet corrections. Within the limitations of this review, both procedures seem to offer comparable skeletal and overjet stability outcomes; however, further high-quality research is required to confirm these findings.

Abstract
OBJECTIVE Unerupted permanent teeth are amongst the most commonly occurring dental anomalies in adults and present unique treatment challenges. The aim of this retrospective study was to (1) identify the prevalence of adult patients with unerupted teeth attending a multidisciplinary clinic and (2) to identify predictors (age, gender, incisor and skeletal classification) which influence the patients treatment decision. MATERIAL AND METHODS Consecutive adult patients with unerupted permanent teeth attending the Joint Orthodontic-Restorative clinic were identified. Study variables were collected using a prespecified data collection form. Descriptive statistics were employed; Fisher's exact test was used to detect associations between variables and treatment decision outcome. Ordinal logistic regression derived multinomial regression relative risk ratios (RRR) and 95% confidence intervals (CI) were calculated for the effect of age, gender, incisor and skeletal classification on treatment decision/outcome. RESULTS Sixty-six patients with impacted teeth were identified from a sample of 483. The prevalence of adults with unerupted teeth was 13.7%. The mean age was 30.7 years (SD 11.2). The majority of the sample had a Class I incisor relationship (54.6%) or Class I skeletal base relationship (54.6%), and the most common distribution of impacted teeth was a single unerupted upper right canine (34.9%). Orthodontic treatment (non-extraction or extraction basis incorporating the alignment or removal of impacted teeth) and restorative treatment only were equally favoured. Factors including age, gender, incisor and skeletal classification did not appear to influence or predict the final treatment decision. CONCLUSIONS In this sample, adults presenting with impacted teeth favoured certain treatment modalities: orthodontic treatment only and restorative treatment only. Factors such as age, gender, incisor and skeletal classification did not influence the outcome.

Abstract
The presence of root resorption and its correlated factors are concerns that must be considered in orthodontic planning. This case report describes the orthodontic retreatment of a patient with a dental to facial midline discrepancy, a severe apical root resorption, and with maxillary and mandibular incisors presenting accentuated labial tipping and protrusion. The treatment included self-ligating brackets, maxillary unilateral distalization with skeletal anchorage and a mandibular extraction, followed by retraction. The orthodontic planning was based on simple and efficient mechanics and the treatment duration was of 19 months. Based on the acceptable final results it can be assumed that the treatment choices enabled a successful approach, maintaining a stable root condition.

Abstract
INTRODUCTION A growing number of adult patients are seeking orthodontic treatment. This research aimed to analyze the particulars of patients seeking retreatment and identify the causes of their original treatment failure. METHODS An online questionnaire survey of adults seeking first-time orthodontic treatment (control) and retreatment (study) was conducted. Index of complexity, outcome, and need (ICON) scores were determined. Appraisal of treatment records was carried out to identify the causes of original treatment failure. RESULTS No significant differences were found between retreatment adult patients and first-timers regarding reasons for seeking orthodontic treatment, malocclusion type, self-perception of malocclusion, level of self-motivation, willingness for surgery, expectations of treatment improvement and duration. The predominant reason for seeking treatment in both groups was for aesthetic concerns. Retreatment patients presented with lower ICON scores (39.4; standard error, 0.26) than the first-time patients (54.3; standard error, 0.23), P ≤0.001. The predominant reasons for original treatment failings were poor treatment, maturational changes, inadequate retention, shortcomings in diagnosis and treatment planning, and unfavorable growth. Other causes were related to transverse deficiency, secondary malocclusion (after periodontal breakdown), poor retention compliance, and temporomandibular joint degeneration. CONCLUSIONS Adult orthodontic retreatment and first-time seekers' profiles are remarkably similar. Aesthetic concerns were the leading reasons patients sought treatment. ICON was not a useful proxy of patient profiles. Poor treatment was the chief reason for the failure of the original treatment. In terms of clinical significance, clinicians should be mindful of the patient profiles of retreatment seekers and vigilant about the possible causes of failings of orthodontic treatment to avoid suboptimal outcomes.

Abstract
The demand for orthodontic treatment in adults has been increasing. However, these patients often require a multidisciplinary approach, due to the lack of posterior teeth, requiring additional anchorage. The skeletal anchorage by endosseous implants is an option, since they may be used later for prosthetic rehabilitation. The application of immediate load on these appliances for orthodontic movement may reduce the costs and total treatment time. This paper discusses the utilization of endosseous dental implants with immediate load for absolute anchorage for orthodontic movement, with later utilization for prosthetic rehabilitation.

Abstract
Background
Adult patients used to be daunted with the prospect of having fixed appliances to correct malocclusions. However, this has gradually changed and recent literature reported an increasing trend in adults receiving orthodontic treatment. To date, there has been no information regarding the trend of adult orthodontic patients in Singapore.
Objective
The objective of this study was to determine the changes in the proportion of adult patients seeking orthodontic treatment at the National Dental Centre Singapore (NDCS) from 2011 to 2017.
Materials and Methods
The study sample consists of all patients who commenced active orthodontic treatment from 2011 to 2017 at the NDCS. The data collected were analyzed for the number, gender, and proportion of adult orthodontic patients treated annually from 2011 to 2017. Linear-by-linear association test was used to test for any significant linear trend in proportion of adult orthodontic patients over the 7 years. Pearson’s Chi-squared test was used to test for any significant gender differences.
Results
There was a significant increasing linear trend (p = 0.001) in the proportion of adult orthodontic patients from 2011 to 2017. No significant difference (p = 0.770) between the proportions of male and female adults undergoing orthodontic treatment was found. The ages of adults undergoing orthodontic treatment ranged from 21 to 73 years old and majority (48.61%) of them was in the 21–25 years old age range.
Conclusion
There is a rising trend in adults seeking orthodontic treatment at the NDCS from 2011 to 2017. No statistically significant gender difference was observed in this rising trend.

Abstract
The purpose of this study was to evaluate the change in three-dimensional morphology and clinical symptoms of temporomandibular joint (TMJ) in class III dentofacial deformity patients postoperatively for 6 months after sagittal split ramus osteotomy (SSRO).Seventeen patients with skeletal Class III malocclusion and 10 asymptomatic volunteers (classified as Control group) were recruited for the study and underwent cone-beam computed tomography scanning. The geometries of the maxilla and mandible were reconstructed using MIMICS (Materialise, Leuven, Belgium). The morphologic measurements of the patients' TMJs were done before surgery and at 6-month follow-up - named as Pre and Post groups, respectively.The joint spaces (medial joint space, superior joint space, lateral joint space, anterior joint space, and posterior joint space) of the Control group were significantly greater than those of the Pre and Post groups (P < .05), and SSRO did not significantly change the TMJ morphology parameters. Five patients were found to have preoperative temporomandibular disorder (TMD) symptoms, and 3 of them were relieved at 6 months after surgery. Postoperative TMD symptom was observed in 1 patient without preoperative TMD symptom.SSRO did not markedly alter the TMJ morphology of the patients with mandibular prognathism. The effects of SSRO on TMD symptoms should be related to the type of deformity.

Abstract
Successful orthodontic treatment of adult cases depends on the biological, mechanical, and esthetic requirements of patients. While customized lingual appliance systems meet the esthetic expectations of the patients, they provide improved patient comfort, have three-dimensional mechanical control, and can be used for the treatment of all types of malocclusions. This report demonstrated the use of fully customized lingual orthodontic brackets for treating an adult case with extraction.

Abstract
INTRODUCTION The objective of this 4-arm parallel study was to evaluate the alignment efficiency and esthetic performance of 4 coated nickel-titanium archwires over an 8-week period. METHODS Patients in the permanent dentition requiring maxillary and mandibular fixed orthodontic treatment with a preadjusted edgewise appliance were eligible for inclusion. Patients attending 4 hospital departments (United Kingdom and Italy) were randomly allocated to 1 of 4 treatment interventions: (1) BioCosmetic (Forestadent, Pforzheim, Germany), 0.017 in; (2) Titanol (Forestadent), 0.016 in; (3) TP Aesthetic (TP Orthodontics, La Porte, Ind), 0.014 in; and (4) Tooth Tone (Ortho Organizers, Calsbad, Calif) 0.016 in. Block randomization with block sizes of 4 and 8 was used to ensure an allocation ratio of 1:1:1:1. The primary outcome was alignment efficiency determined by the reduction in Little's irregularity index (mm). Secondary outcomes were color change using the Commission Internationale de L'Eclairage L*a*b* system and percentage of coating loss. Blinding was only applicable to outcome assessment of alignment efficiency. Regression models with Sidak's multiple comparison of means were used to analyze the data. RESULTS One hundred fifty patients (300 dental arches) were allocated to the treatment interventions, including 61 male and 89 female subjects with a mean age of 16.60 years. The average duration of follow-up was 63.65 days. Baseline characteristics for the archwire groups were similar. One patient was lost to follow-up. Five percent (n = 15) of the archwires fractured: BioCosmetic, 5.3% (n = 4); Titanol, 6.8% (n = 5); TP Aesthetic, 5.3% (n = 4); and Tooth Tone, 2.7% (n = 2). We analyzed 283 dental arches for alignment efficiency. There was no statistically significant difference for mean reduction in irregularity between the archwire groups (P = 0.627): BioCosmetic (n = 71), 3.86 mm (95% CI, 3.31-4.41); Titanol (n = 69), 4.51 mm (95% CI, 4.00-5.02); TP Aesthetic (n = 71), 4.13 mm (95% CI, 3.49-4.78); and Tooth Tone (n = 72), 4.21 mm (95% CI, 3.89-4.46). There was a statistically significant difference between archwire groups for color change (P = 0.001) and percentage of coating loss (P = 0.001), with BioCosmetic performing best in both parameters. CONCLUSIONS There was no difference between the archwires for alignment efficiency. BioCosmetic performed statistically significantly better than did the other groups for both color change and coating loss. REGISTRATION This trial was registered with the East Midlands NHS Research Ethics Committee (12/EM/0190). PROTOCOL The protocol was not published before trial commencement.

Abstract
Objective This paper describes changes in the characteristics of patients seeking orthodontic treatment over the past decade and the treatment they received, to identify any seasonal variations or trends. Methods This single-center retrospective cohort study included all patients who presented to Seoul National University Dental Hospital for orthodontic diagnosis and treatment between January 1, 2005 and December 31, 2015. The study analyzed a set of heterogeneous variables grouped into the following categories: demographic (age, gender, and address), clinical (Angle Classification, anomaly, mode of orthodontic treatment, removable appliances for Phase 1 treatment, fixed appliances for Phase 2 treatment, orthognathic surgery, extraction, mini-plate, mini-implant, and patient transfer) and time-related variables (date of first visit and orthodontic treatment time). Time series analysis was applied to each variable. Results The sample included 14,510 patients with a median age of 19.5 years. The number of patients and their ages demonstrated a clear seasonal variation, which peaked in the summer and winter. Increasing trends were observed for the proportion of male patients, use of non-extraction treatment modality, use of ceramic brackets, patients from provinces outside the Seoul region at large, patients transferred from private practitioners, and patients who underwent orthognathic surgery performed by university surgeons. Decreasing trends included the use of metal brackets and orthodontic treatment time. Conclusions Time series analysis revealed a seasonal variation in some characteristics, and several variables showed changing trends over the past decade.

Abstract
BACKGROUND Orthodontic treatment may cause functional restrictions, discomfort, and pain, which may lead to dental anxiety and noncooperation among patients. This study aimed to assess the concerns of adult female patients with respect to such treatment. PATIENTS AND METHODS We conducted an explorative study using Q methodology among 40 adult female patients with different educational and social backgrounds in Wenzhou, People's Republic of China. We asked participants to rank a set of 41 statements about seeking orthodontic treatment on an 11-point scale from "agree most" to "disagree most". The collected data were analyzed using the PQ Method 2.35 program. We extracted significant viewpoints using centroid factor extraction and varimax rotation. RESULTS We identified major factors based on how the patients ranked statements. Patients in group 1 worried about lack of information about orthodontic treatment, and may have suffered from dental phobia; patients in group 2 were all single women, and they were worried that the braces might lower their chances of finding a partner; patients in group 3 worried about appearance and speech with braces; and patients in group 4 worried about cost, pain, and dental hygiene. The remaining participants who had other viewpoints did not load to any of these four groups. CONCLUSION The concerns of adult female individuals seeking orthodontic treatment are complex. A significant feature of this study was using Q methodology to analyze the psychological characteristics of the patients. This study identified four typical characterizations that are associated with each group, and our findings may aid orthodontists in improving doctor-patient relationships.

Abstract
OBJECTIVE The aim of this study was to develop a patient-based measure of the process and outcome of combined orthodontic and orthognathic care in the National Health Service in the UK. DESIGN Identification of relevant dimensions through qualitative methods, design of form, determination of psychometric properties of the scale, specific readability, reliability and validity. SETTING NHS hospitals in the South West Region. SUBJECTS The sample comprised patients who had received combined orthodontic and orthognathic treatment between 01 January 1998 and 31 December 2000. Twenty-six participants (a 25% response rate) took part in four focus group meetings. Thirty subjects (65% response rate) took part in a pilot study to test the properties of the questionnaire. MAIN OUTCOME MEASURES Six broad themes emerged from the focus groups. These formed the basis of the sections in the questionnaire. RESULTS The questionnaire developed had a Flesch reading ease score of 72.9 or US grade level 4 equivalent to aged 9-10 years. Test-retest reliability gave kappa values for most questions that exceeded 0.4. Criterion validity of the measure was established by comparing responses to the questionnaire over two periods with a telephone interview on a sample of 30 patients. Criterion related validity was poor for nine of the 16 items. By contrast the construct validity of the questionnaire was satisfactory. CONCLUSION A patient-based measure of the process and outcome of combined orthodontic and orthognathic treatment has been developed. This has sufficient validity and reliability for use in inter-center audit projects.

Abstract
OBJECTIVE: The purpose of this study was to analyze the psychological aspects of adult patients who sought and underwent orthodontic treatment, evaluating their expectations and discomfort during treatment, as well as their satisfaction after completion of dental movement. RESULTS AND CONCLUSIONS: Data obtained from previous published papers, and also from questionnaires answered by 54 patients, showed that adult patients stood out for their attention to details and high interest in the esthetic improvements provided by treatment, and also for a greater perception of their initial malocclusion. On the other hand, the same data showed that adult patients, once informed about the limitations of their treatment and having confidence on the orthodontist, presented a high level of satisfaction with treatment results, revealing themselves as good patients for indication and execution of orthodontic procedures.

Abstract
Since so many decades, various treatment modalities have been presented for the treatment for the class II, div 1 malocclusions. In recent times, we have seen enormously increasing numbers of young adults who desire the shortest, cost effective and a non surgical correction of Class II malocclusions and they accept dental camouflage as a treatment option to mask the skeletal discrepancy. This case report presents one such case of a 22 year old non-growing female who had a skeletal Class II, division 1 malocclusion with an orthognathic maxilla, a retrognathic mandible, a negative VTO and an overjet of 12mm, who did not want a surgical treatment. We considered the camouflage treatment by extracting the upper first premolars. Following the treatment, a satisfactory result was achieved with an ideal, static and a functional occlusion, facial profile, smile and lip competence and stability of the treatment results.

Abstract
OBJECTIVE: This study evaluated the influence of orthodontic appliances on smile esthetics assessed by lay adolescents, lay adults and orthodontists. METHODS: A facial photograph of a smiling young woman was used under the following conditions: With metal orthodontic brackets ligated by different elastic ligature colors (green, red and gray), with ceramic bracket brackets (transparent elastic ligature) and without brackets, totaling five 15 x 20 cm pictures. For the photograph assessment, 16 lay adolescents, 16 lay adults and 16 orthodontists were randomly selected. The photographs were randomly arranged in an album, followed by a visual analog scale (VAS) for the scores registration. Scores in both evaluations of each group of evaluators (adolescents, adults and orthodontists) were submitted to error analysis by WILCOXON test and multiple comparison among groups performed by Kruskal - Wallis at 5% significance. RESULTS: Orthodontists, adults and adolescents agreed in their opinions, although the orthodontists gave lower scores in their assessments. It could be observed that ceramic brackets were more acceptable concerning the smile esthetics, whereas the metal brackets received the lowest scores. CONCLUSION: Orthodontists, adults and even adolescents seem to prefer esthetic solutions during orthodontic treatment.

Abstract
OBJECTIVE To analyse the staining properties of clear orthodontic brackets using a digital analysis. DESIGN In vitro, laboratory study MATERIAL AND METHODS A total of 500 tooth-coloured brackets from 10 brands (five ceramic and five plastic) were investigated. The cumulative discolouring effect of staining agents (tea, coffee, curry and red wine) were analysed at two consumption levels: light and heavy, based on a 6-month period of exposure. Study group brackets were immersed in the agents consecutively at 37°C. The control group was only exposed to artificial saliva. Samples were analysed digitally to obtain L*, a* and b* (lightness, red-green and yellow-blue) colour readings. Using these values, total colour change (ΔE*) at each level was also calculated. Three-way analysis of variance (ANOVA) test was used for statistical comparisons. RESULTS L* and b* colour parameters showed significant differences (P<0·001) between different bracket groups, consumption levels and the type of exposure. However, the a* value only differed between bracket groups (P<0·001). According to the ΔE* values, ceramic brackets had less colour change than plastic brackets at the end of phase 1 for both the study and control groups. However, as consumption time increased, the rate of colour change decreased for the plastic brackets. In general, ceramic brackets demonstrated much more resistance to staining agents than plastic brackets. CONCLUSIONS Both plastic and ceramic brackets showed changes in colour when exposed to heavy consumption of staining agents, with plastic brackets being the most affected.

Abstract
INTRODUCTION In recent years, the demand for adult orthodontic treatment has grown rapidly; yet there is a paucity of information on this subgroup of patients. It is well known that understanding the psychological characteristics and motives of any patient is fundamental and that these factors might affect patient satisfaction and adherence with treatment. There is therefore a need for clinicians to improve their understanding of this subgroup to enhance the patient's experience of treatment delivery and to increase the potential for a successful treatment outcome. The aim of this study was to develop a measure for the assessment of motivating factors and psychological characteristics of adults seeking orthodontic treatment. METHODS This study involved the qualitative development of a valid patient-centered questionnaire to assess motivating factors for adults seeking orthodontic treatment. This was achieved through semi-structured in-depth interviews; key themes were identified and used to construct a questionnaire assessing motivation for treatment. This was then combined with 3 previously validated questionnaires to measure self-esteem, anxiety or depression, and body image and facial body image. The questionnaire was distributed to 172 adult orthodontic patients at different stages of treatment in a large teaching hospital in the United Kingdom. In addition, the self-esteem, body image, and facial body image scores were compared with data on orthognathic patients from the same hospital and with data from members of the general public. RESULTS Desire to straighten the teeth and improve the smile were the key motivating factors for the adult group studied. Other motives included to improve the bite, improve facial appearance, and close (dental) spacing. With respect to the psychological characteristics of self-esteem, body image, and facial body image, the adult orthodontic group was comparable with the general public. However, differences were noted when comparing data from the adult orthodontic group with previously collected data on orthognathic patients. CONCLUSIONS The motives for adults to seek orthodontic treatment are numerous and varied, whereas psychological traits appear to be closer to those of the general public than to orthognathic patients.

The quality of treatment in the adult orthodontic patient as judged by orthodontists and measured by the Objective Grading System. Am J Orthod Dentofacial Orthop 2011; 139:S69-75.

Abstract
INTRODUCTION The increase in adult orthodontic patients in the last 20 years makes it more likely that a clinician will have adult cases to present to the American Board of Orthodontics (ABO) for board certification. The applicability of the Objective Grading System (OGS) to adult dentitions, however, has not been reported. Therefore, the purpose of this study was to determine if well-treated adult cases, as designated by orthodontists, could pass the ABO clinical examination using the OGS. METHODS Posttreatment casts of 35 adult patients from Temple University, Department of Orthodontics were ranked by 4 examiners based on visual examination of the quality of case finish using the Q-sort method. Data on each examiner's personal selection criteria to classify a well-treated case were gathered. Discrepancy index (DI) and OGS scores were measured, and the number of missing teeth was recorded. RESULTS There was a moderate correlation between the rankings of the 4 examiners and their rankings to the OGS score. A 63% overall ABO pass rate was found. The pass rate for the well-treated cases and failure rate in the lower ranked group were both 100%. The DI scores of 97% of the cases were high enough to qualify as a board case, and 77% had 1 or more missing teeth after treatment. Examiners largely used the factors of the OGS in deciding if a case was well treated, with intercuspation being the most important factor. CONCLUSIONS This study demonstrates that well-treated adult cases can pass the ABO clinical examination using the OGS. In addition, it illustrates that missing teeth automatically inflate the DI score and improve the OGS score.

Abstract
AIM This study examined how halitosis, oral dryness and general oral health were impacted during treatment with the Invisalign(®) system. Furthermore, the effect of a lowdose chlorhexidine solution (CHX) was evaluated. PATIENTS AND METHODS Thirtyone patients with good periodontal health participated in this crossover study and were divided into two groups (group 1: CHX/no CHX, group 2: no CHX/CHX). The following parameters were recorded during the first 8 months of Invisalign(®) treatment: stimulated saliva flow rate, organoleptic index, tongue coating index, measurement of the oral volatile sulfur compound level (ppb), modified gingival and plaque index and bleeding on probing index. Professional oral cleaning was performed at the beginning of each period lasting 3 months. The patients received a questionnaire at the first, third, fourth, sixth and eighth control visits. RESULTS The very low volatile sulfur compound level was significantly decreased by CHX (0.06%) during the first examination period (p = 0.02), i.e. for the first group of patients only. Neither halitosis, nor oral dryness, nor high plaque or gingival index measurements were observed. Oral health-related quality of life was hardly influenced by wearing aligners and oral hygiene habits were very good. CONCLUSIONS This study provides evidence that Invisalign(®) treatment is characterized by only minimal impairment of overall oral health and the associated quality of life. Consequently, it appears unnecessary to recommend the general adjunctive use of a low-dose chlorhexidine mouthwash during treatment with Invisalign(®).

Abstract
Objective: To determine whether Herbst treatment is more efficient in adolescent than in adult Class II division 1 subjects.
Materials and Methods: All Class II division 1 patients with a full secondary dentition who had been treated at the orthodontic department of the University of Giessen with a Herbst appliance between 1990 and 2000 were considered. The complete records of 77 patients were available. According to their skeletal maturity, as assessed on hand-wrist radiographs, the subjects were divided into an adolescent group (MP3-F to MP3-H; n = 49; mean age 13.5 years) and an adult group (R-IJ to R-J; n = 28; mean age 20.7 years). Pretreatment and posttreatment dental casts were evaluated using the Peer Assessment Rating (PAR) Index. The reductions in PAR scores of the two groups were compared.
Results: Before treatment, both groups had a severe Class II division 1 malocclusion. The average PAR score of the adolescent patients was slightly lower (27.8) than that of the adult patients (28.8). After treatment, good results were reached for both groups, and the average PAR scores of the two groups were comparable (adolescents: 4.5; adults: 4.8). The average reductions in PAR score were 82.7% (23.3 points) for the adolescent group and 82.9% (24.0 points) for the adults, indicating great improvement in both groups.
Conclusions: Because good treatment results were achieved, with substantial improvement of the pretreatment situation in both groups, Herbst treatment can be considered equally efficient in adolescent and in adult Class II division 1 subjects.

Abstract
INTRODUÇÃO: a análise facial tem sido um recurso diagnóstico valorizado desde os primórdios da Ortodontia. Vários autores tentaram estabelecer referências de normalidade na direção das quais os pacientes ortodônticos deveriam ser tratados. Essa preocupação da Ortodontia está em concordância com a expectativa do paciente, cuja principal motivação para o tratamento ortodôntico é a melhora estética. Para que os objetivos do profissional possam solucionar a queixa do paciente é fundamental que o ortodontista conheça os parâmetros utilizados pela sociedade na avaliação estética. Sugerimos, por meio desse trabalho, uma nomenclatura que permita a realização da Análise Facial Subjetiva, estética e morfológica. OBJETIVO: avaliar a aplicação prática da análise. METODOLOGIA: solicitou-se a um grupo heterogêneo de avaliadores (14 ortodontistas, 12 leigos e 7 artistas) que dessem notas ao perfil facial de 100 indivíduos (50 de cada gênero) classificando-os como esteticamente desagradáveis (notas 1, 2 ou 3), esteticamente aceitáveis (notas 4, 5 ou 6) e esteticamente agradáveis (notas 7, 8 ou 9). RESULTADOS: 89% dos perfis foram esteticamente aceitáveis, 8% desagradáveis e 3% agradáveis. Em 38,35% das justificativas, o nariz foi a estrutura responsável pela estética desagradável, seguida pelo mento ("queixo") em 18,9% dos relatos. CONCLUSÃO: foi possível observar, portanto, que a Análise Facial Subjetiva é mais um instrumento diagnóstico, que tem sua importância aumentada por ser o parâmetro pelo qual o paciente e as pessoas com as quais ele convive vão avaliar os resultados do tratamento.

Abstract
This study assessed bonding of orthodontic brackets to porcelain teeth using two different surface preparation techniques and comparing two bonding systems, Fuji Ortho L.C. and Transbond. Four groups of 20 porcelain premolar teeth were bonded with metal orthodontic brackets (0.022 inch Minitwin, 3M Unitek) according to the following protocol: Transbond with a phosphoric acid etch (group 1), Transbond with a hydrofluoric acid etch (group 2), Fuji Ortho L.C. with a hydrofluoric acid etch (group 3), and Fuji Ortho L.C. with a phosphoric acid etch (group 4). All groups were bonded with a silane coupling agent. The teeth were debonded with an Instron universal testing machine. Bond strength, site of bond failure and adhesive remnant index (ARI) were recorded for each group. Differences between groups were analysed statistically. The composite resin groups (groups 1 and 2) had the highest mean bond strength values at 7.9 and 9.7 MPa, respectively. The resin-modified glass ionomer cement groups (RMGIC; groups 3 and 4) had the lowest mean bond strength values at 6.3 and 1.8 MPa, respectively. The mean bond strength of group 3 was significantly lower than all other groups (P < 0.0001). The Fuji groups had also significantly (P < 0.001) lower ARI scores than the composite groups (groups 1 and 2). Most samples experienced porcelain surface damage, except group 4. In conclusion, the highest bond strength levels were achieved with a conventional composite resin cement (groups 1 and 2). No significant differences in bond strength were found between the hydrofluoric and phosphoric acid etch technique.

Abstract
One important aspect in evaluating the outcome and quality of orthodontic treatment is the patient's own assessment. The objective of this study was to evaluate the course and outcome of orthodontic treatment in adults from the patient's vs the operator's point of view. In a previous study, the orthodontic treatment of 88 adults was evaluated using the IOTN and PAR Index before and after treatment. Fifty-nine patients answered treatment questionnaires on 1. the reason for seeking treatment, 2. dentofacial aesthetics, 3. treatment outcome, 4. course of treatment, 5. attitude, 6. social well-being. Depending on the original treatment goal, the patient population was divided into an Ideal Group and a Compromise Group. In 75% of the patients, dissatisfaction with dental aesthetics was the prime motive for seeking treatment; correlations with PAR parameters (overjet and maxillary anterior teeth) were weak. In general, a high degree of patient satisfaction with orthodontic treatment was registered. As regards satisfaction with post-treatment dental aesthetics there were no significant differences between the groups. Comparison of professional assessment with the subjective rating by patients revealed discrepancies in that the patients' rating of outcome tended to be more positive. The differentiation between ideal and compromise treatment goals proved useful. In the Compromise Group, a high level of patient satisfaction was attained with a shorter treatment duration and lower appliance involvement. 92% considered their major pre-treatment need to have been met, and 95% would have had the treatment performed again.

Abstract
The aim of this study was the retrospective evaluation of the outcome of orthodontic treatment in consecutively treated adult patients. Of 147 adult patients, it was possible to evaluate the records of 88 patients (57 female, 31 male) before (T1) and after treatment (T2), and of 20 of these patients 3.3 years on average after completion of the retention phase (T3). During treatment planning, a nearly "ideal" result was considered attainable (ideal group) for 46 patients, and a "compromise" result (compromise group) was seen as realistic for 42. The assessment was made using the PAR (Peer Assessment Rating) index and the Aesthetic Component (AC) and Dental Health Components (DHC) of the IOTN (Index of Orthodontic Treatment Need). Average length of treatment in the ideal group was 2.4 years, i.e. nearly twice as long as in the compromise group. The PAR score was reduced by an average of 56% (T2); the reduction in the ideal group was 73%, and in the compromise group 37%. Among the 20 patients for whom at least 6 months had elapsed since completion of the retention phase, a statistically significant relapse between T2 and T3 was observed. The evaluation of overjet and overbite and, in the ideal group, of the midline and maxillary front teeth were primarily responsible for the worsening of the PAR scores between T2 and T3. According to the AC, 53 patients (60%) had moderate to definite treatment needs at the beginning of treatment. Following completion of active treatment, 69 patients (78%) no longer demonstrated treatment indications for aesthetic or psychosocial reasons. Based on the DHC, 88% of the patients were in definite or moderate need of treatment (T1); in contrast, treatment was no longer indicated in 84% at T2. In general, a marked improvement of the examined morphological parameters was observed.

Abstract
An international survey has been undertaken to assess variation in professional assessment of orthodontic treatment need. Ninety-seven orthodontists from nine countries examined a standard sample of 240 dental study casts to judge the need for orthodontic treatment in terms of dental health, dental esthetics, and deviation from normal. Participants also indicated their assessment of treatment complexity and whether they would recommend treatment. Practitioners' subjective assessments were found to be only moderately reliable overall. Of the cases examined, 76% [corrected] obtained a consensus of 80% or greater on the need for treatment. Logistic regression equations were derived to explain the observed variation in treatment decisions. It was found that occlusal traits from the dental casts were highly predictive of the treatment decision, and that the practitioners' country of origin and payment methods are important influences on prescribing behavior. The treatment decisions were predicted with an accuracy of 84% by using occlusal score values for the dental esthetics, the degree of upper arch crowding, the presence of crossbite, the anterior overbite, and the buccal segment sagittal relationship. It is suggested that these traits may form the basis for an internationally validated index of treatment need for use in clinical audit and orthodontic research.

Abstract
Canadian orthodontists were surveyed by mail to determine the latest skeletal age at which they would recommend orthopedic therapy and orthognathic surgery and the earliest at which they would recommend orthognathic surgery. For the purposes of this introductory study, orthopedic therapy implied stimulation of physiologic response using appliance force, without specification of appliance type. Response rate from 512 orthodontists was 65% (n = 334), with the response rate by item varying from 92% to 95%. By Greulich and Pyle standards, the latest recommended age for orthopedic therapy was at 97% completion of skeletal growth (females 13.5 years, males 15 years), whereas the earliest recommended age for orthognathic surgery was when skeletal growth is 99% complete (females 14.9 years, males 16.5 years). Surgery would be recommended by 32% of respondents for a patient before the age of 8 years, if deformity is severe. For orthognathic surgery, respondents either perceived no age maximum or recommended 69 years, the maximum age on the questionnaire item. Orthodontists' traits influenced recommendations for timing treatment.

Abstract
The orthodontic management of patients with profound learning disability is described including a report of two cases. Close co-operation between the orthodontist and other providers of dental treatment is essential for the management of this group of patients, and a general anaesthetic may be needed to allow fixed appliances to be placed. The orthodontic treatment is co-ordinated with any necessary restorative or periodontal treatment. The moral and ethical questions raised by the treatment offered to this group of patients are discussed.

Abstract
Orthodontists are often concerned about the prognosis of root-filled teeth, particularly when extractions are required for orthodontic treatment. This review provides guidance on assessing the quality of root fillings, as well as the factors which affect the prognosis of root-filled teeth. The implications of previous traumatic injuries and the likelihood of root resorption during orthodontic tooth movement are discussed.

Abstract
The effect on distal molar occlusion following mandibular orthognathic surgery is highlighted. Two cases are presented in which at the completion of orthodontic/surgical treatment a stable molar occlusion was re-established by adjunctive restorative treatment. The clinical problem highlighted, illustrates the importance of restorative support for patients with residual post-orthodontic and post-surgical occlusal problems.

Abstract
The increased demand for orthodontic treatment by adults suggests a review of the literature might be timely. In this review we explore whether the increased in demand is real and matched by need. We also examine the reasons for treatment being sought and special considerations which are important during orthodontic treatment. Finally, we compare the orthodontic experience of adults and adolescents. We conclude that adults seeking treatment can be excellent patients with high motivation and co-operation. The limitations of orthodontic treatment must be explained at the beginning of treatment since adult expectations of orthodontics can be very high.
