Abstract
Missing maxillary lateral incisors can be treated either with orthodontic space closure or preservation of the edentulous space for tooth replacement. Orthodontic space closure coupled with non-invasive post-orthodontic cosmetic dentistry is a compelling option compatible with optimal function, favourable aesthetics, and periodontal health in the long-term. We present the rationale for space closure and detail contemporary clinical strategies underpinning interdisciplinary treatment planning and excellence in finishing.

Invisible treatment of an asymmetric adult class II malocclusion related to unilateral upper lateral incisor agenesis with a straight wire lingual appliance, mini-screw and premolar extraction: A case report. Int Orthod 2023; 21:100721. [PMID: 36610255 DOI: 10.1016/j.ortho.2022.100721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 12/11/2022] [Accepted: 12/13/2022] [Indexed: 01/07/2023]
Abstract
This case report describes a complex full-step class II malocclusion with unilateral upper lateral incisor agenesis in an adult patient treated with lingual straight-wire appliance and premolar extraction, with the two-fold aim of obtaining ideal occlusal relationship and smile aesthetic improvement. In view of this, it underlines how an appropriate treatment strategy, including extraction choice and anchorage control during space closure, is needed to achieve the planned results with a completely invisible lingual appliance combined with aesthetic veneers.

Abstract
INTRODUCTION It is important to achieve proper root position during orthodontic treatment involving future dental implant placement. However, current methods to evaluate root position are either inaccurate or expose patients to relatively high radiation levels. A new approach using an expected root position (ERP) setup has previously demonstrated the potential to accurately monitor root position with minimal radiation. This study aimed to evaluate whether the ERP setup is an accurate and reliable method to determine if the roots adjacent to an edentulous site are appropriate for the anticipated dental implant. METHODS In this retrospective study, the ERP setup was generated for 22 edentulous sites selected from the University of California San Francisco Division of Orthodontics patient database. The mesiodistal angulation of all teeth adjacent to the edentulous sites and the mesiodistal space between the teeth were measured in the ERP setup and compared with the posttreatment cone-beam computed tomography (CBCT) scan, which served as the control. The intraoperator and interoperator reliability and agreement between the ERP setup and the posttreatment CBCT scan were assessed using Bland-Altman analysis. The correlation between measurements was further evaluated by the Pearson correlation coefficient. RESULTS The Bland-Altman plots and the Pearson correlation coefficient displayed strong agreement between the ERP setup and the posttreatment CBCT scan, with only 11.4% mesiodistal angulation measurements beyond the clinically acceptable range of ± 2.5°. All mesiodistal angulations and distances were strongly correlated with high intraoperator and interoperator reliabilities. CONCLUSION The method to generate an ERP set up to evaluate the mesiodistal angulation and space of an edentulous site prepared for a future dental implant has been demonstrated to be accurate and reliable.

Abstract
Background: Individuals with tooth agenesis often present a significant clinical challenge for dental practitioners. This retrospective study evaluated clinical and radiological long-term functional and esthetic outcomes following restoration using primary teeth to support fixed all-ceramic prosthesis in patients with teeth agenesis. Methods: Patients with teeth agenesis and at least one year follow-up were included. Examinations included panoramic X-ray, clinical examination and family history records. Only primary teeth without permanent teeth underneath were chosen. All ceramic fixed restorations were used. All data were collected from patient files. Outcome parameters included: restoration parameters (restoration survival, restoration fractures, restoration detachment, restoration replacement, and secondary caries), plaque index, and gingival index. Results: The study included 58 porcelain restorations inserted in 25 individuals; mean age 12 ± 2.1 years (range 10–19 years); mean number of missing teeth 12.3 ± 9 (range 6–12). Mean follow-up 48 ± 6 months (range 12–60 months). All restorations survived up to last follow-up, rendering a survival rate of 100%. Restorations outcome—porcelain chipping (9%), detachment (2%), no restoration replacement nor secondary caries, mean gingival index—0.7 ± 0.5 and mean plaque index—0.9 ± 0.3. Conclusions: In tooth agenesis, restoration using primary teeth to support fixed all-ceramic prosthesis is a viable treatment alternative.

Abstract
INTRODUCTION The aim of this systematic review was to provide guidelines for decision-making during orthodontic treatment planning of infra-occluded deciduous molars with or without their successors in children and adolescents. EVIDENCE ACQUISITION Computerized search was conducted on Medline via PubMed, and Cochrane Library. Articles published until 2020 in English language were analyzed following the Preferred Reporting Items for Systematic Reviews (PRISMA) Checklist. Observational and interventional longitudinal studies reporting the treatment of ankylosed deciduous molars with or without successor tooth in 3 to 15-year-old patients were included. EVIDENCE SYNTHESIS In case of ankylosis with presence of successor, exfoliation took place in 77% of teeth, while extraction involved 23%. Infra-occlusion happened in 53% of teeth (worsening in 52%), alveolar bone loss in 37%, mesial tipping of first permanent molar in 5%, and over-eruption of antagonist in no cases (after exfoliation and eruption of successor). In case of ankylosis without successor, exfoliation took place in 1% of teeth, progression of infra-occlusion in 42%, progression of root resorption in 58%, development of mesial tipping of first permanent molars in 25%, while no case of antagonist over-eruption was reported. CONCLUSIONS When the permanent tooth is present and the ankylosed tooth is slightly or moderately infra-occluded, observation is appropriate. In case of severe infra-occlusion or absence of successor, tooth extraction may be considered together with orthodontic space closure, transplantation, or prosthetic replacement. Alternatively, nonextraction and a prosthetic build-up may be considered.

Green MA, Padwa BL. Does Timing of Secondary Alveolar Bone Grafting Affect the Need for Additional Bone Augmentation Prior to Implant Placement at Cleft Sites? J Oral Maxillofac Surg 2021; 79:1927-1931. [PMID: 34119476 DOI: 10.1016/j.joms.2021.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 05/04/2021] [Accepted: 05/05/2021] [Indexed: 11/28/2022]
Abstract
PURPOSE The purpose of this study was to identify factors that influence the need for a supplemental bone graft prior to dental implant placement at previously grafted alveolar cleft sites. PATIENTS AND METHODS Retrospective case series of patients with cleft lip/palate who had both alveolar bone grafting (ABG) and placement of a dental implant(s) to replace a missing incisor(s) at the cleft site by the senior surgeon (BLP) at Boston Children's Hospital from 2005 through 2020. Primary outcome variable was need for a supplemental bone graft prior to dental implant placement. Predictor variables included gender, cleft type (unilateral vs. bilateral), implant site, number of implants placed, age at ABG and implant placement, time between ABG and implant, history of maxillary expansion and whether the patient had a Le Fort I osteotomy to correct maxillary hypoplasia before implant placement. Descriptive statistics were computed and comparative analyses were performed using Pearson X2, Fisher exact, and Mann-Whitney U tests. RESULTS There were 84 implants placed in 59 patients (64.2% female) with cleft lip and palate who had alveolar bone grafting of which 57.1% (n = 48) required a supplemental graft prior to placement. Median time (IQR) from alveolar bone grafting to implant placement was significantly longer in patients who required additional grafting (8.1 versus 5.4 years, P < .001). Patients who required supplemental bone were significantly younger at the time of alveolar bone grafting (10.1 versus 12.3 years, P < .001). Cleft sites in patients who had a Le Fort I osteotomy prior to implant placement required bony augmentation more often than cleft sites in patients who did not have a Le Fort I osteotomy (58.7% versus 33.3%, P = .03). CONCLUSIONS Patients with cleft lip and/or palate who undergo alveolar bone grafting should be counseled that they are likely to require a supplemental bone graft prior to implant placement.

Abstract
This case report describes the unusual choice of extraction of maxillary incisors with short roots as part of an orthodontic treatment plan. The patient was a 20-year-old woman referred to our department in whom the diagnosis was maxillary protrusion and open bite. Both of the maxillary central incisors had short roots. Two treatment options were considered. The first involved extraction of the 4 first premolars with the aim of improving dentoalveolar protrusion and crowding. If preservation of the central incisors subsequently became difficult due to root resorption, prosthetic options were to be considered. The second treatment option involved extraction of the maxillary central incisors with short roots and the mandibular first premolars. The second treatment option was selected as survival of the central incisors following orthodontic movement was uncertain and the patient also wanted to minimize the risk of future extractions and the use of prosthetics. Active treatment was performed over a span of 31 months, and circumferential type retainers were used on both arches for retention. For such treatment to be successful, careful diagnosis and orthodontic treatment planning must be taken to ensure the anterior dental esthetics are properly restored.

Abstract
OBJECTIVES This research aims to retrospectively evaluate the clinical performance of Carolina bridge (CB) placed at a dental school. MATERIALS AND METHODS Data were collected from the electronic patient record system. A follow-up letter was sent to the subjects' mailing address explaining the research purpose along with a questionnaire to assess their satisfaction with the treatment. A phone interview was performed to assess patient satisfaction, function, and choice of permanent restoration. Finally, a clinical exam was conducted for patients that agreed to come for a follow-up and still had their CBs. RESULTS Twenty-three patients with 26 resin-bonded CBs met the inclusion criteria. All patients who did the phone interview reported to be very satisfied with the treatment. Most chose to keep the CB as definitive treatment and not to move forward with implant therapy. According to the number of rebonding needed to maintain the CB, the types of survival were analyzed as 42.3% complete survival (no rebonding needed), 26.9% functional survival (rebonded once), 23.1% survival with multiple rebondings, 7.6% failure. CONCLUSION The performance of CBs revealed highly acceptable performance with high-patient satisfaction. CLINICAL SIGNIFICANCE Carolina ridge is an esthetic and conservative interim treatment option that can be utilized in favorable clinical situations.

Abstract
Dental agenesis is one of the most common developmental anomalies in humans. It occurs as part of a genetic syndrome or as an isolated sporadic or familial finding. Third molars, second mandibular premolars and maxillary lateral incisors are the most frequently targeted teeth of the permanent dentition. Clinically, patients with congenitally missing permanent teeth seeking treatment present with unesthetic diastemas, midline deviation and tilting of adjacent teeth in the edentulous areas. The impact of tooth agenesis reflects on esthetics, function, psychological and social well-being of the individuals affected. Orthodontics can contribute to the treatment plan selected by rearranging the present teeth so as to open spaces for prosthetic restorations or close spaces by reshaping teeth if needed. Following orthodontic space opening/maintaining, the usual alternatives involve single implants, two-(cantilever) or full coverage(cantilever) prostheses. Less frequently, the treatment modality of autotransplantation is proposed with a good esthetic result but feasible only in young patients where the roots of the premolars are still developing. In orthodontic space closure, treatment is accomplished sooner without waiting for the completion of growth of the patient. Depending on various factors such as the malocclusion, the dento-skeletal profile, the smile line, the space requirements, the teeth missing, the periodontal issues, the age of the patient and any financial issues, the clinician will determine the most appropriate treatment approach. The final esthetic and functional result should resemble an intact natural dentition.

Abstract
Objective: This article describes the orthodontic treatment performed on an adult patient with multiple dental losses. Case report: A female patient, 20 years and 4 months old, presented with the following conditions: absence of teeth #26, #35, #36 and #46; semi-impacted tooth #48; inclined molars adjacent to an edentulous space; canines and premolars in a Class II relationship; a convex profile; biprotrusion; and forced lip sealing. Results: Space in the region of tooth #26 was closed, as well the space of tooth #46; tooth #48 erupted and followed mesial movement passively; space of the region of tooth #35 was maintained for the placement of a dental implant; uprighting of tooth #37 was obtained. Aesthetic and functional goals of the treatment were achieved. Results remained stable 10 years after the end of the treatment. Conclusion: The modified helical loop could be effectively used in orthodontic mechanics to close edentulous spaces. Passive semi-impacted mandibular third molar eruption and mesialization can occur in adults when proper space is provided.

Abstract
Leeway space and E-space plays a crucial role in the late transition phase from primary dentition to permanent dentition. Leeway space is normally 0.9 mm and 1.5 mm in upper and lower arch respectively. E-space is the difference in the mesiodistal width of deciduous second molar and permanent second premolar which is 2.3 in upper arch 2.5 mm in lower arch 1. E-space and leeway space are normally utilized by permanent first molars to establish class I molar relation in permanent dentition. We can also utilize this E-space during fixed orthodontic treatment for reliving of crowding in late mixed dentition. Thus, here in this article, we are presenting clinical technique along with case series of sequential utilization of E-space for correction of anterior crowding without extractions.

Abstract
INTRODUCTION Missing or peg-shaped maxillary lateral incisors can affect the mesiodistal dimensions of the dentition. METHODS The pretreatment casts of patients with bilateral (BMLI, n = 35) or unilateral (UMLI, n = 29) missing maxillary lateral incisors or bilateral peg-shaped maxillary lateral incisors (BPLI, n = 16) were evaluated. The mesiodistal widths of all permanent teeth except the second and third molars were measured, and the sums of total and quadrant tooth widths were calculated. The results were compared with a control group (n = 32) with normal maxillary lateral incisors. A quadrant analysis was performed by comparing the quadrants with lateral incisor agenesis, peg-shaped lateral incisors, and normal lateral incisors with each other. Statistical analysis was performed by 1-way analysis of variance followed by Tukey and Tamhane tests. RESULTS In the BMLI and BPLI groups, significant reductions in individual tooth widths and total tooth widths were seen. The size discrepancies were the greatest in the maxillary central incisors and decreased gradually from the incisors to the molars. Compared with the control group, the tooth-size discrepancy was more pronounced in the BPLI group followed by the BMLI and UMLI groups. Due to the variability in clinical presentations of the UMLI group, the association with the reduction of the tooth sizes was not significant. But the quadrant analysis showed that in quadrants with a missing or peg-shaped lateral incisor, the teeth were significantly narrower than in quadrants with normal incisors; this indicates the importance of the contralateral side in unilaterally affected patients during analysis. CONCLUSIONS Bilateral missing or peg-shaped maxillary lateral incisors were significantly associated with reduction of individual mesiodistal tooth widths as well as their total and quadrant sums. Patients with a unilaterally missing lateral incisor should be analyzed individually with quadrant analysis, since the variability in the contralateral side would affect the traditional analysis results.

Abstract
OBJECTIVE Assess whether the permanent maxillary canine (MC) has a natural tendency to erupt mesially in children with maxillary lateral incisors agenesis (MLIA), compared to children without agenesis. STUDY DESIGN This retrospective, observational, cross-sectional study consisted of children between 5 and 12 years old divided into three groups: the first group with unilateral MLIA, in which an intraindividual analysis was performed, the second group presented bilateral MLIA, and the third group with patients without agenesis. These last two groups were matched for comparison interindividual, being pared by sex and maturation of the MC. RESULTS The canine position in the horizontal sector showed a clear mesial positioning of the MC on the agenesis side in individuals with unilateral MLIA (group 1) when compared with the counter lateral side; and in individuals with bilateral MLIA (Group 2) compared with control Individuals without agenesis (group 3). Even with the maintenance of this deciduous tooth in the dental arch, the MC keeps its tendency to mesial eruption. CONCLUSION There is a greater tendency for mesial angulation of the maxillary canine in patients with MLIA, regardless of the presence or absence of deciduous lateral incisor.

Abstract
This case report presents the clinical use of a resin nanoceramic CAD/CAM restoration of a primary second molar without successor in the form of a permanent second premolar tooth in a patient. Three-year follow-up of the case revealed that resin nanoceramic CAD/CAM restoration of the primary molar without successor achieved both aesthetics and function. Despite the high cost of treatment, this type of restoration should be considered if the retained tooth is expected to maintain functionality over the long term.

Abstract
Bone defects at the anterior regions of the jaws often cause esthetic problems such as gingival disharmonies and longer crowns than neighboring teeth. Variety of procedures can be used in this region for achieving sufficient bone volume with or without different bone graft materials. All of these procedures has their own advantages and disadventages. New bone formation was defined with orthodontic tooth movement in different regions. In this case we present the use of orthodontic tooth movement, for achieving sufficient bone volume, in anterior maxillary region, for esthetic and functional results.

Abstract
The objective of this study was to compare the dimensional changes in the alveolar ridge before, at the end of, and one year after orthodontic treatment in cases of Maxillary Lateral Incisor Agenesis and the possibility of using plaster models and panoramic radiographs as substitutes for cone beam-computed tomography. MATERIAL AND METHODS A total of 228 measurements were performed on plaster models and panoramic radiographs: before (T1), at the end of (T2), and 1 year after orthodontic treatment (T3). At stage T2, the cone beam-computed tomography was also analyzed. Non-parametric tests were used. RESULTS In all 3 stages, there was no statistically significant difference regarding the thickness of the models, the height of the bone in the panoramic radiographs, the space opening and the height of the bone in the panoramic radiographs, or the space opening in the models and the thickness in the same plaster models. However, a statistically significant difference was observed for the width in the panoramic radiograph during all 3 stages. Cone beam-computed tomography did not reveal a statistically significant correlation regarding the height and width of the bone compared with the panoramic radiographs, and the thickness as compared with plaster models. CONCLUSION There was no significant variation in thickness, height and width of the bone over time. It was demonstrated that plaster models and panoramic radiographs do not appear to be good substitutes for cone beam-computed tomography for these specific measurements.

Abstract
The clinical problem of how best to manage a dilacerated, impacted maxillary central incisor will only be encountered rarely. The treatment aim should be to achieve results that are indistinguishable from normal appearance in a way that is appropriate for the patient. This article discusses the incidence of dilacerations in maxillary incisors and describes the treatment approaches available − orthodontic alignment or surgical removal and management of the resulting space, considering orthodontic repositioning, autotransplantation and various prosthetic replacements. Treatment indications, advantages and disadvantages, restorative and surgical implications, as well as the evidence-base relating to the various treatment modalities will be presented, along with clinical case examples. Clinical relevance: This paper discusses a problem that, if not managed appropriately, can lead to poor results for the patient. Even for practitioners who may not undertake the treatment mentioned, it will enable them to have more in-depth discussion with their patients should the situation arise.

Abstract
OBJECTIVES To evaluate (i) a possible correlation between the mesio-distal gap width and the alveolar ridge (AR) dimensions in patients missing the maxillary lateral incisor (I2) either due to agenesis or loss and (ii) the possibility of straightforward implant placement based on simulation. METHODS The bucco-palatal width, area, and height of the AR at the position of I2, and the mesio-distal gap width between the central incisor and the canine, were assessed in maxillary CT scans of three groups: Patients with (i) agenesis of I2 (TA ; n = 40); (ii) I2 regularly erupted but extracted (TL ; n = 24); (iii) I2 regularly erupted and in situ (C; n = 40). Further, the possibility of straightforward placement of an implant 3 or 3.5 mm in diameter ×10 mm in length, with 1 mm distance from the buccal and palatal plate of the alveolar ridge was simulated and compared to the actual treatment delivered. RESULTS Bucco-palatal width and area of the AR at I2 and the adjacent teeth was significantly reduced in TA compared to TL and C. Further, in TA , but not TL , an increasing mesio-distal gap width between the central incisor and canine resulted in a significantly reduced bucco-palatal width of the edentulous AR. This impeded a simulated straightforward implant placement in >50% of the cases in TA , even with a reduced implant diameter. CONCLUSIONS In patients congenitally missing I2, an increased mesio-distal gap width correlates significantly with reduced edentulous AR dimensions. A mesio-distal gap of >6 mm was associated with thin bucco-palatal alveolar ridges, precluding straightforward implant placement in 60-80% of the cases.

Abstract
OBJECTIVE This clinical report describes an alternative treatment modality for the replacement of congenitally missing maxillary lateral incisors in a 17-year-old patient. CLINICAL CONSIDERATIONS Zirconia-based resin-bonded fixed partial dentures (RBFPDs) were selected as a viable and conservative treatment option in a young individual with highly aesthetic expectations. Fabrication of all-ceramic RBFPDs followed specific preparation design and features to accommodate two retainers. The zirconia frameworks with bilateral wings were digitally designed and then milled by a computer-aided design and computer-aided manufacturing (CAD/CAM)-controlled milling machine. Zirconia surface was treated with a two-step chairside tribochemical silica-coating/silane coupling surface treatment protocol, and adhesive resin luting cement was used to achieve micromechanical and chemical bonding. Completion of the treatment resulted in a functional and aesthetic successful outcome and a 17-month follow-up presented uneventful. CONCLUSION Contemporary adhesive techniques involving resin-bonded zirconia-based prostheses can be utilized successfully and predictably in young patients with single missing teeth when implant therapy is currently not a treatment of choice and a less invasive approach is desired. CLINICAL SIGNIFICANCE The zirconia-based resin-bonded prosthesis constitutes a viable and conservative treatment modality for the replacement of missing teeth either congenitally or from another etiology in young patients in which implant therapy and a fixed partial denture are currently contraindicated.

Abstract
BACKGROUND Facial growth in the vertical dimension is the last to be completed and can often be detrimental to the success of dental implants, orthodontic treatment, and orthognathic surgery that young individuals undergo. AIM The purpose of this study was to evaluate the longitudinal relationship between changes in total anterior facial height and insulin-like growth factor-1 (IGF-1) levels measured using blood-spot samples. METHODS Our sample included 25 orthodontic patients from whom we had access to annual lateral cephalometric radiographs and IGF-1 measurements. Each subject was observed between 2 and 6 times, resulting in 43 annual intervals from a total of 77 observations. RESULTS We noted a significant moderate positive correlation (+ 0.48) between the percentage of change in blood-spot IGF-1 levels and the percentage of change in total anterior face height (p = 0.01). CONCLUSION Longitudinal changes in IGF-1 levels can be used to predict a patient's vertical facial growth. There was no significant correlation between changes in vertical facial development and a single cross-sectional IGF-1 measurement.

Abstract
Implant placement is often necessitated for replacement of teeth with pathologically damaged alveolar bone due to periodontitis or traumatic injury. Surgical augmentation of resorbed bone has many limitations, including lower efficacy of vertical augmentation than horizontal augmentation, as well as morbidity associated with grafting procedure. Orthodontic therapy has been proposed as a useful method for augmenting the resorbed alveolar bone and reforming aesthetically appealing gingival margin, prior to implant placement. This narrative review summarizes the available evidence for the application of orthodontic strategies that can be used as adjunct in selected cases to augment bone volume for the future implant site and maintain space for the prosthetic parts of the implant. These are (1) orthodontic extrusion of compromised teeth to generate vertical bone volume and enhance gingival architecture, (2) tooth preservation and postponing orthodontic space opening to maintain bone volume in future implant site, (3) orthodontic implant site switching to eliminate the deficient bone volume or risky implant sites, and (4) the provision of a rigid fixed-bonded retainer to maintain the implant site. Although there are no randomized controlled clinical trials to evaluate the efficacy of orthodontic therapy for implant site development, clinical case reports and experience document the efficacy of orthodontic therapy for this application.

Abstract
Maxillary central incisors have the least incidence of congenital absence. When it does happen, the patient may present with over retained deciduous centrals or the contralateral central may have drifted into the available space presenting as generalised anterior spacing with loss of midline. In such cases a multi-disciplinary approach may be required with orthodontic treatment to re-organise the space available in order to rehabilitate the patient with a fixed prosthesis. This case report presents the treatment of a patient with congenitally missing maxillary left central incisor using dental implant with angulated abutment after orthodontic correction and stabilization of the remaining maxillary anteriors.

Abstract
The missing maxillary lateral incisor in adolescent patients presents an orthodontic challenge. Historically, there have been three treatment options to address this clinical problem: (1) canine substitution, (2) tooth auto-transplantation, and (3) dental restoration. Unfortunately, these methods are not without limitation. A novel treatment concept, originating in 2003 and utilizing orthodontic miniscrew implants, is presented along with the rationale, clinical technique and 8 years of follow-up.

Abstract
Implant by definition "means any object or material, such as an alloplastic substance or other tissue, which is partial or completely inserted into the body for therapeutic, diagnostic, prosthetic, or experimental purpose." The placement of a dental implant in an extraction socket at the time of extraction or explantation is known as immediate implant placement whereas delayed placement of implant signifies the implant placement in edentulous areas where healing has completed with new bone formation after the loss of tooth/teeth. Recent idea goes by "why late when it can be done immediately." There are several advantages of immediate placement of implants, and lots of studies have been done. In this article, the advantages and disadvantages of immediate versus delayed placement of implants have been reviewed.

Abstract
Background The aim of this retrospective study was to compare the esthetic, periodontal, and functional outcomes of orthodontic space closure versus implant substitution in patients with missing maxillary incisors 5 years after completion of treatment. Methods The study group consisted of ten patients treated with orthodontic space closure (six males, four females, mean age 19 ± 2.1 years at the completion of treatment) and ten patients treated with implant insertion (five males, five females, mean age 20 ± 1.4 years at the time of implant insertion). Tooth mobility, plaque index, probing depth, infraocclusion, open gingival embrasure (black triangle), and temporomandibular joint function were recorded at the 5.6 years follow-up. Self-perceived dental esthetic appearance was also evaluated through a visual analog scale (VAS) questionnaire. T-test was used to evaluate the data. Results All patients were equally satisfied with the appearance of their teeth 5.6 ± 0.4 years after the completion of treatment. No statistically significant differences were found in relation to the VAS scores of the subjects (P < 0.857). No significant differences were found in tooth mobility, plaque index (P < 0.632), and the prevalence of signs and symptoms of temporomandibular disorders. However, significant infraocclusion was noticed in all implant patients (P < 0.001). Probing depth was also significantly higher in implant patients (P < 0.001). Conclusions Orthodontic space closure and implant of missing maxillary incisors produced similar, well-accepted esthetic results. None of the treatments impaired temporomandibular joint function. Nevertheless, infraocclusion was evident in implant patients. Space closure patients also showed better periodontal health in comparison with implant patients.

Abstract
Dentists have several treatment options when restoring patients with congenitally missing maxillary lateral incisors. Endosseous implant therapy combined with orthodontics can achieve predictable outcomes while meeting patient expectations. This case report exhibits an interdisciplinary approach involving orthodontics, implant surgery, and prosthodontics to resolve this common dental concern.

Abstract
The use of implant-supported restorations in patients with hypodontia remains challenging and requires a multistage treatment that begins in late mixed dentition and continues into late adolescence. The aim of this article is to review the role of orthodontics in endosseous implant rehabilitation of patients with hypodontia. The MEDLINE, Web of Science, Scopus, Cochrane databases, and necessary scientific textbooks were searched for relevant studies and reviews, and as far as possible, they were only included if they had been cited at least once in the literature. Dental implants are susceptible to overloading as the periodontal ligament is absent and the proprioceptive nerve endings are either lacking or very limited. Patients with hypodontia may present with skeletal features such as short and retrognathic maxilla, prognathic mandible, and shorter lower anterior facial height, and they sometimes need orthognathic correction as part of their overall treatment. Dental problems vary and include bimaxillary retroclination of incisors, spacing, centerline discrepancies, microdontia, hypoplastic enamels, ankylosis of the retained primary teeth, overeruptions, and volume deficiencies of alveolar ridges. The challenges mentioned, as well as bone volume deficiencies, compromise the successful placement of implants. Orthodontic strategies and techniques, such as uprighting mechanics, extrusion/intrusion, delayed space opening, and orthodontic implant site-switching, can be used to create, preserve, or augment the implant site. After orthodontic site development, the final planned position of the teeth should be maintained with a rigid bonded retainer; overlooking this stage may compromise the implant site and require orthodontic retreatment.

Abstract
Tooth agenesis is one of the most common developmental dental anomalies. Successful and satisfying dental treatment is always the goal for patients and dental practitioners, meaning that a patient's needs are solved in a functional and esthetic way. Patients and dentists have to find the best way to reach their common goal of satisfaction. The authors introduce and provide examples of different approaches to solve the problem of congenitally missing lateral incisors. This article discusses the restorative approach, the approach using implants, and the orthodontic approach. In most cases, an interdisciplinary treatment plan has to be worked out and executed.

Abstract
This case report describes a Class I crowded malocclusion with an ankylosed maxillary central incisor that was in infraocclusion and labially displaced. The patient had wide maxillary teeth, and the option of extracting the maxillary central incisors followed by space closure, with lateral incisors substituting for the central incisors, was chosen.

Postorthodontic root approximation after opening space for maxillary lateral incisor implants. Am J Orthod Dentofacial Orthop 2010; 137:158.e1-; discussion 158-9.

Abstract
INTRODUCTION Orthodontic space opening during adolescence is a common treatment for congenitally missing maxillary lateral incisors. Because of continued facial growth and compensatory tooth eruption, several years can elapse between completion of orthodontic treatment for a teenage patient and implant placement. There are reports that, after successful orthodontic opening of the implant space, the central incisor and canine roots reapproximate during retention and prevent implant placement. METHODS To study this phenomenon, the records of 94 patients with missing maxillary lateral incisors were collected. Periapical and panoramic radiographs were used to measure intercoronal and interradicular distances between the central incisor and the canine adjacent to the missing lateral incisor before and after orthodontic treatment and at implant placement. RESULTS Although root approximation between the adjacent central incisor and canine during retention did not occur consistently, 11% of the patients experienced relapse significant enough to prevent implant placement. CONCLUSIONS To ensure sufficient space for implant placement, we recommend at least 6.3 mm of intercoronal space and 5.7 mm of interradicular space between the adjacent central incisor and canine. A bonded wire or resin-bonded bridge will help to reduce root approximation that might occur during retention.
