Abstract
A congenitally missing lateral incisor tooth is commonly associated with both short and long-term clinical dilemmas, particularly for a growing patient. A unilaterally missing maxillary lateral incisor tooth creates a significant dental asymmetry in the critical aesthetic zone of the smile and potentially increases the difficulty of any subsequent orthodontic and restorative treatment. Carefully planned interdisciplinary management is required to address the challenges of anterior dental asymmetry, unilateral orthodontic space closure and to alleviate the concerns that accompany restorative implant placement in the anterior maxilla. The use of skeletal temporary anchorage devices has increased the predictability of orthodontic space closure, particularly for missing maxillary lateral incisor cases which were previously considered to be unsuitable.

Alveolar morphometry in young adults with and without agenesis of the upper lateral incisor: A retrospective study. Int Orthod 2024; 22:100864. [PMID: 38417225 DOI: 10.1016/j.ortho.2024.100864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 02/06/2024] [Accepted: 02/08/2024] [Indexed: 03/01/2024]
Abstract
INTRODUCTION We aimed to compare alveolar morphometry in young adults with agenesis of the upper lateral incisor versus the side without agenesis and versus matched controls. MATERIAL AND METHODS In this observational retrospective study, cone beam computed tomography scans were obtained of 36 upper hemiarches from young adults aged 15 to 30 years. The hemiarches were distributed into three groups: group 1: 12 upper hemiarches presenting agenesis of the upper lateral incisor; group 2: 12 upper hemiarches from the opposite side without agenesis of the upper lateral incisor (control group 1); and group 3: 12 upper hemiarches without agenesis of the upper lateral incisor matched for age and sex with respect to the affected group (control group 2). A trained and calibrated investigator performed all the alveolar measurements at two different times, including sagittal, coronal and axial slices of each hemiarch. Paired Student's t-tests, Chi-square and repeated measures ANOVA with Bonferroni correction were used, (P<0.05). RESULTS Apical mesial evaluation of group 1 (4.22±1.19mm) was significantly lower (P<0.001) than that of groups 2 (6.72±1.17mm) and 3 (7.58±1.67mm). Apical distal evaluation also showed differences (P<0.001) among the three groups, with the dimension being smaller in group 1 with agenesis (4.53±1.14mm), followed by group 2 without agenesis (6.23±1.55mm) and the healthy control group 3 (7.73±1.71mm). CONCLUSIONS Lateral incisor agenesis significantly reduces the alveolar dimensions of the affected area. In cases of unilateral agenesis, the unaffected side also shows sequelae, with decreased dimensions compared to cases without agenesis. This condition should be taken into account when making therapeutic decisions regarding rehabilitation with implants or canine replacement.

Abstract
The aetiology of impacted canines is multi-factorial. Several theories have been proposed, such as lack of space, genetic predisposition, physical barriers like supernumerary teeth, odontomas and other conditions that interfere with the eruption pathway. One of the main complications that can be generated by impacted canines is the resorption of the root of the adjacent teeth. This case report examines the importance of interdisciplinary management of maxillary incisors with root resorption caused by impacted canines in a 13-year-old male patient. Careful traction of impacted canines and proper tissue management followed by space closure and retroclination of anterior incisors with orthodontic treatment. Finally, functional and aesthetic results using dental veneers for oral rehabilitation allowed the patient to obtain favourable results.

Abstract
OBJECTIVE This case report demonstrates an interdisciplinary approach to treat a 26-year-old male patient with hyperdivergent Class II skeletal pattern, maxillary transverse deficiency, slight anterior open bite, and multiple hopeless teeth with root rests. CLINICAL CONSIDERATIONS An interdisciplinary treatment was required for oral hygiene improvement, caries treatment, extraction of residual roots and hopeless teeth, maxillary expansion using microimplant-assisted rapid palatal expansion, improvement of skeletal and dental relationship using orthodontic microimplants, and prosthetic restorations with the aid of dental implants. CONCLUSION Consequently, esthetic and functional occlusal rehabilitation was achieved. CLINICAL SIGNIFICANCE Hyperdivergent Class II facial and skeletal patterns with multiple missing teeth can be effectively treated using orthodontic skeletal anchorage. In young adults, the transverse discrepancy can be resolved using MARPE, which is also useful for improving the sagittal and vertical relationships. In the case of multiple missing teeth, orthodontic treatment can provide the proper space to facilitate dental implants to achieve optimal esthetics and function.

Abstract
OBJECTIVES To assess the long-term aesthetic and functional aspects of implant-supported crowns in lateral (ISC-L) and canine positions (ISC-C). MATERIALS AND METHODS Thirty-two patients (14 males, 18 females, mean age: 23.1, SD:2.0) with an ISC-L or ISC-C participated in this prospective cohort study at baseline (T0) and in the long-term follow-up (T1, mean years: 11.1, SD: 1.0). Twenty-four patients (11 males, 13 females) participated in T1. Patient-reported outcomes (PROM) were rated using surveys with questions related to aesthetics and function. The colour of the implant crown and the buccal gingiva, the appearance of the papilla, periodontal health and temporomandibular disorder (TMD) outcomes were assessed in a clinical examination. The Mann-Whitney, Chi-square and Signed Rank tests were performed. RESULTS Patients with an ISC-L and ISC-C were equally satisfied with the crown shape and colour at T0 and T1. No differences in TMD outcomes were reported by the patients and no clinical signs of TMD were observed. At T1, ISC-C had more bleeding on probing and a three mm greater pocket depth than ISC-L (p = 0.03, p = 0.01, respectively). At T0, operators graded the crown colour of ISC-L as being too dark (35%) and ISC-C as being too light (40%). At T1, no difference was seen between the two groups regarding crown colour, gingiva colour and the papilla (p = 0.2749, p = 0.2099, p = 0.8053, respectively). CONCLUSIONS The PROM and clinical examination show that ISC-L and ISC-C are equivalent with regard to aesthetics and function in the long term. CLINICAL RELEVANCE Although ISC-L and ISC-C are aesthetically and functionally comparable in the long term, ISC-Cs are more likely to impact periodontal health.

Abstract
INTRODUCTION This research aimed to evaluate the impact of orthodontic treatment on a young person's oral health-related quality of life, self-esteem, and esthetics concerning hypodontia. METHODS A prospective longitudinal hospital-based study recruited 97 participants with hypodontia, aged 11-18 years. Forty-one participants (42%) originally planned to have space closure and the remainder space opening, with subsequent prosthetic replacement. The following questionnaires were completed before and after orthodontic treatment: the child perception questionnaire, Bristol condition-specific questionnaire for hypodontia (BCSQ), the child health questionnaire, and the Oral Aesthetic Subjective Impact Scale (OASIS). The Wilcoxon and matched pairs t tests approach was applied to compare before and after orthodontic treatment for significant testing (P <0.05). RESULTS Fifteen participants were lost to follow-up, resulting in 82 participants completing orthodontic treatment, with an average age of 13.8 ± 1.71 years. A total of 282 teeth were missing in the sample. Treatment resulted in significantly lower indexes (P <0.001) to overall BCSQ, OASIS, appearance, and how others would treat them. In comparing the 2 subgroups, those treated with space closure had significantly reduced functional limitations (child perception questionnaire), appearance concerns, self-esteem (child health questionnaire), OASIS, and overall BCSQ scores. CONCLUSIONS Orthodontic treatment in participants with hypodontia appears to significantly impact a range of psychological and esthetic scales. In particular, space closure appears to significantly improve the quality of life of participants compared with those undergoing space opening.

Abstract
Patients with one or more developmentally absent teeth are routinely encountered in dental practice. Tooth agenesis can be associated with significant functional, aesthetic and psycho-social problems. The present article provides an overview of the prevalence and aetiology of tooth agenesis, as well as the condition's clinical characteristics and management options with reference to the evidence base. A timely diagnosis can facilitate the appropriate planning and management which might not be straightforward, and patient care will likely require multi- and inter-disciplinary input. It is critical that dental care practitioners are aware of the clinical characteristics and management options for tooth agenesis.

Abstract
Sotos syndrome is a genetic disorder characterized by distinct craniofacial features, overgrowth in childhood, and impaired intellectual development. We herein report the successful orthodontic treatment of a 14-year-old boy with Sotos syndrome caused by a heterozygous mutation in the NSD1 gene. He showed severe hypodontia, impaction of the maxillary second molars and a skeletal Class III jaw-base relationship. Orthodontic management, including space control by protraction of the maxillary first molars and traction of the impacted molars, was performed using fixed appliances and miniscrews. As a result, acceptable occlusion was obtained without any discernible relapse 18 months postretention.

Abstract
OBJECTIVE Few studies within orthodontics present both economic and clinical findings. Missing maxillary lateral incisors is a frequently occurring anomaly. The treatment alternatives most used are orthodontic space closure and prosthetic replacement of the missing tooth. Our aim is to compare the total societal costs of orthodontic space closure (SC) and implant therapy (IT) in patients missing maxillary lateral incisors. METHODS Records of 32 patients treated with SC (n = 18) or IT (n = 14) due to missing maxillary lateral incisors were retrieved from the archives. Direct costs and indirect costs in the short- and long-term were analysed using a cost analysis with a societal perspective up of to 12 years post-treatment. RESULTS Comparing cases treated with SC and IT, the difference in direct short-term costs for treatment is €735.54, whereas SC is the least costly. There is no difference between SC and IT in short-term parent loss of productivity, long-term loss of productivity, costs for transportation, or direct long-term costs. A difference was found between SC and IT-in favour of SC-when comparing patients' loss of productivity (P = 0.007), short-term societal costs (P < 0.001), long-term societal costs (P = 0.037), and total societal costs (P < 0.001). LIMITATIONS There is a limited number of patient records. Local factors such as subsidies, urban versus rural areas, taxes, etc. can influence monetary variables, so the transferability to other settings may be limited. CONCLUSION Patients treated with SC have a lower total societal cost compared to patients treated with IT. There was a difference in productivity loss for patients between SC and IT; however, concerning other indirect parameters and direct long-term costs, there was no difference between the two treatments.

Abstract
Management of lateral incisor agenesis is a real challenge and needs a strong collaboration between surgical, aesthetic, and orthodontic dentistry. This case report managed upper lateral incisor agenesis with an orthodontic treatment leading to open spaces and placement of cuspids in lateral incisor area to avoid implant placement in maxillary anterior region. Temporary rehabilitation phase, using resin injected tray and removable partial denture, has been placed to maintain mesiodistal dimensions and restore aesthetic during pre-implant analysis and osseointegration. Once osseointegration was fully obtained, keratinized tissue augmentation has been obtained using connective tissue graft. Then, temporary implant fixed crowns allowed soft tissue modeling during interim rehabilitation. Finally, screw-retained permanent crowns were placed to fully restore aesthetic and function. This case goal was to optimize final results and reach patient complete satisfaction using orthodontic treatment combined with implant rehabilitation, and coupled with interdisciplinary management and well-time sequencing treatment.

Abstract
BACKGROUND AND OBJECTIVE Agenesis of the maxillary lateral incisor occurs in up to 4% of all individuals and requires multidisciplinary treatment. Its developmental origins, however, are not fully understood. Earlier studies documented genetic factors contributing to agenesis but also an association with craniofacial morphology. In this study, we assessed the association between maxillary morphology and lateral incisor agenesis by a geometric morphometric approach to disentangle the roles of developmental plasticity and genetic factors. MATERIALS AND METHODS We quantified the maxillary alveolar ridge by 19 two-dimensional landmarks on cross-sectional images of 101 computed tomography scans. We compared the shape and size of the alveolar ridge across patients with unilateral or bilateral agenesis of maxillary lateral incisors and patients with extracted or in situ incisors. RESULTS The maxillary alveolar ridge was clearly narrower in patients with agenesis or an extracted incisor compared to the control group, whereas the contralateral side of the unilateral agenesis had an intermediate width. Despite massive individual variation, the ventral curvature of the alveolar ridge was, on average, more pronounced in the bilateral agenesis group compared to unilateral agenesis and tooth extraction. CONCLUSIONS This suggests that pleiotropic genetic and epigenetic factors influence both tooth development and cranial growth, but an inappropriately sized or shaped alveolar process may also inhibit normal formation or development of the tooth bud, thus leading to dental agenesis. CLINICAL RELEVANCE Our results indicate that bilateral agenesis of the lateral incisor tends to be associated with a higher need of bone augmentation prior to implant placement than unilateral agenesis.

Abstract
Oronasal fistula can persist after conventional secondary alveolar bone graft surgery, which may lead to functional issues, such as regurgitation of fluids from the oral to the nasal cavity. This manuscript describes a clinical case of a patient with a bilateral cleft lip and palate that underwent tongue graft surgery for closure of an oronasal fistula after three failed local mucosa flap surgeries. The multidisciplinary treatment was comprised of orthodontic treatment, mucosa and alveolar grafts for palate closure and aesthetic rehabilitation of the anterior maxillary teeth. Smile aesthetics were noticeably improved, enhancing the patient’s self-perception and confidence.

Abstract
BACKGROUND Maxillary lateral incisors (MLI) are frequently missing in cleft patients. The aim of this study was to assess how orthodontic gap closure or prosthetic rehabilitation of the missing MLI affected the dental arch relationships and symmetry at the end of treatment. We also aimed to determine the impact of the level of oral hygiene on the decision made to manage the missing MLI gap. METHODS A descriptive, retrospective cohort study including all cleft patients born between 1980 and 1999 treated at Nantes Cleft Center was performed. Patients presenting unilateral or bilateral missing MLI were reviewed. Data about management of the missing MLI gap, dental arch relationships, symmetry and level of oral hygiene were collected. RESULTS Four hundred and eighty-six cleft patients were reviewed, including 212 patients with unilateral or bilateral missing MLI. When compared to orthodontic gap closure, prosthetic replacement of the MLI gap was associated with better final dental arch relationships (59.8% vs. 10.3%; p<0.01) and better dental arch symmetry (88.1% vs. 44.0%; p<0.01) for unilateral missing MLI cases but not for bilateral missing MLI cases. A better level of oral hygiene was associated with more cases with prosthetic replacement for unilateral missing MLI cases (p=0.03) and had no impact for bilateral missing MLI cases. CONCLUSION Prosthetic replacement of the missing MLI gap provided better functional and esthetic results for cleft patients presenting with unilateral missing MLI.

Abstract
Introduction: There are different possibilities of orthodontic planning for cases with congenital absence of maxillary lateral incisors. This subject divides the opinion of orthodontists and oral rehabilitation clinicians, due to the advantages and disadvantages of each treatment option, which may involve opening spaces for future implants and/or prosthetic restorations, or closing the spaces by positioning the maxillary canines in the place of lateral incisors. The correct diagnosis and careful evaluation of each patient allow to determine the best therapeutic approach. This paper discusses the main topics to be considered when planning these cases. Objectives: To evaluate the main aspects related to orthodontic treatment planning in cases of congenital absence of maxillary lateral incisors, to aid the decision-making, with clinical and scientific basis.

Abstract
Background and objective Occlusion rehabilitation and restoration are difficult in subjects with congenitally missing lateral incisors, either unilaterally or bilaterally, and often lead to malocclusion and warrant replacement. The present study was conducted to assess the agenesis of maxillary lateral incisor unilaterally and bilaterally and to examine tooth size discrepancy in agenesis subjects undergoing orthodontic treatment. Materials and methods We assessed 32 dental casts of both genders (17 males and 15 females) with missing maxillary lateral incisors either unilaterally or bilaterally. Mesiodistal dimensions were measured and a comparison of tooth sizes was done for control and test groups. The data were assessed and the results were documented. Results Lateral incisors of the maxillary arch were statistically smaller in the test group compared to the control group. This was true for both males and females (p=0.001 for both). A similar finding was observed with respect to the overall study group (p<0.0001). Conclusion Based on our findings, maxillary lateral incisor agenesis plays a role in malocclusion development.

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
New digital technologies, many involving three-dimensional printing, bring benefits for clinical applications. This article reports on the clinical procedure and fabrication of a skeletally anchored mesialization appliance (Mesialslider) using computer-aided design/computer-aided manufacturing (CAD/CAM) for space closure of a congenitally missing lateral incisor in a 12-year-old female patient. The insertion of the mini-implants and appliance was performed in a single appointment. Bodily movement of the molars was achieved using the Mesialslider. Anchorage loss, such as deviation of the anterior midline or palatal tilting of the anterior teeth, was completely avoided. CAD/CAM facilitates safe and precise insertion of mini-implants. Further, mini-implants can improve patient comfort by reducing the number of office visits and eliminating the need for orthodontic bands and physical impressions.

Abstract
There remains debate as to whether, when there is a missing maxillary lateral incisor, space should be orthodontically opened to allow for prosthetic replacement or closed to camouflage the canines to substitute the absent lateral incisor by recontouring and simple restorative procedures. Each case presents its own features which will help decision making. Treatment planning these cases is multifactorial in nature and the decision ultimately depends on factors such as the malocclusion; inter-arch and intra-arch relationship; and canine properties (size, colour and shape). The ideal treatment is the most conservative one that satisfies the individual's aesthetic and functional requirements. Often, but not always, it is therefore space closure with camouflaging of the canines as lateral incisors. Multidisciplinary planning and delivery of care is essential and 'mandatory' in the delivery of optimal outcomes. The first part of this two-part series will discuss the principles of assessment, diagnosis and management. The second part will discuss the challenges encountered and possible solutions.

Abstract
Abstract
The present article reports the successful non-extraction orthodontic treatment using miniscrew anchorage in a patient who presented with maxillary left central incisor loss and unstable jaw movements. The chief complaints of the 23-year-old female patient were her protruding teeth and crowding of the mandibular anterior segment. The patient lost her maxillary left central incisor as a result of a traumatic injury during childhood. However, the crown was saved and attached to the adjacent teeth. The patient was diagnosed with a skeletal Class III and Angle Class III dental malocclusion. The jaw movements determined by a 6 degrees of freedom jaw movement recording system were unstable and irregular. Miniscrew anchorage was applied for distalisation of the maxillary right dentition and the mandibular dentition during non-extraction treatment. The maxillary left dentition was mesialised using miniscrew anchorage to close the space as a result of the lost maxillary left central incisor. After an active treatment duration of 36 months, the patient achieved a Class II molar relationship on the left side, a Class I on the right side, an optimal overjet and overbite, and a pleasing facial profile. Despite the asymmetric molar relationships, functionally stable and smooth jaw movements were established. The skeletal, occlusal and functional stability remained satisfactory after a 2-year retention period. In conclusion, miniscrew anchorage was valuable in supporting asymmetric tooth movement during non-extraction appliance treatment in a patient who presented with traumatic unilateral tooth loss.

Abstract
Objective To investigate laypeople and dental professionals' opinions of the aesthetic outcome from implant therapy (IT) and orthodontic space closure (SC) for missing maxillary lateral incisors. Material and methods Evaluation was performed by three groups: laypeople 20–30 years of age (n = 26), laypeople 50–70 years of age (n = 26) and orthodontists (n = 25). The assessors viewed photographs of 44 different cases treated with IT or SC, and made an evaluation of the aesthetics. Results The gingival color adjacent to the replaced tooth was rated as having better aesthetics in the SC cases (p = 0.000). The orthodontists preferred the aesthetics of the dentition in the SC cases (p = 0.042). The young laypeople, compared to the older laypeople and orthodontists, were more dissatisfied with the color of the tooth replacing the missing lateral incisor in SC cases (p = 0.043). Conclusion The color of the gingiva adjacent to the implant‐supported crowns had a lower aesthetic rating than the SC group. Laypeople rated both treatments as equally good. The orthodontists had a slight preference for the aesthetics in the SC cases.

Abstract
Objectives Implants are used to replace congenitally missing lateral incisors but often the space across the alveolar crest is too narrow to permit their use. This multicenter study (Dental Clinic of the University of Foggia, Odontostomatology Clinic of the University of L’Aquila) evaluated the efficacy of mini-implants in cases of maxillary lateral incisor agenesis with severe osseous atrophy in 10-year follow-up. Materials and methods Forty-seven mini-implants have been inserted in 35 patients affected by lateral incisors agenesis (23 single and 12 bilateral ageneses). All patients underwent orthodontic opening of the space of the upper lateral incisors. After the insertion of the implants, the immediate, non-functional loading, positioning of crowns, presence of pain during percussion and mini-implant function, horizontal and vertical movement when a force of 5 N was applied, ridge loss, and plaque index have been evaluated 1 month after loading, 1 year after loading, and then every 5 years in the following 10 years. Little’s test was used to evaluate the assumption that data of loss to follow-up implants are missing completely at random (MCAR) and that a complete-case scenario could be adopted. Wilcoxon test was carried out to look statistically significant differences between the various parameters resulting in the complete-case scenario and those assumed for the worst scenario. The software R (v. 3.6.1, 2019) was employed to perform the statistical analysis. Results The results obtained over 10 years range from 89% of success rate in a worst-case scenario to the 100% using a complete-case analysis with satisfactory values of marginal bone resorption and good conditions of the peri-implant tissue. Ten-year follow-up using complete-case analysis shows survival rates of 100% for implants with no signs of peri-implantitis, stability of the marginal bone levels and soft tissue around the dental implants. Conclusions The data collected show very good implant stability, absence of progressive peri-implantitis, and satisfactory aesthetical results in time (no signs of infraocclusion). Clinical relevance Mini-implants can be considered a valid and stable over time solution in the restorative treatment of maxillary lateral incisors agenesis.

Abstract
Agenesis of two or more consecutive adjacent permanent teeth (consecutive tooth agenesis, CTA) is a serious manifestation of oligodontia requiring long-term, multi-disciplinary treatment. Therefore, the present study investigated the characteristics of the CTA pattern in orthodontic patients with non-syndromic oligodontia. Using panoramic radiographs, the number of agenetic permanent teeth excluding third molars in non-syndromic orthodontic patients was evaluated, and patients with six or more agenetic teeth (oligodontia group, n = 97) and with one to five agenetic teeth (hypodontia group, n = 107) were selected. The numbers of CTA including third molars in each quadrant and in each patient were compared between the groups. Each quadrant with CTA of patients was categorized into one of the following four types: (I) involves anterior teeth only; (II) involves posterior teeth only; (IIIA) includes anterior and posterior teeth; and (IIIB) separate in the anterior and posterior teeth. CTA in at least one quadrant was found in 91.8 and 4.7% of patients in the oligodontia and hypodontia groups, respectively. The highest frequency CTA patterns included agenesis of the first and second premolars and of the second and third molars in the oligodontia and hypodontia groups, respectively. In the oligodontia group, type IIIA was significantly more frequent in the maxillary than in the mandibular quadrant. Most oligodontia patients who visit orthodontic clinics have CTA. A rare but severe CTA pattern that continues from the anterior to posterior segments is more frequent in the maxillary than in the mandibular quadrant.

Abstract
OBJECTIVES To identify changes in orthodontic management strategies in patients with hypodontia seen in 2000, 2010, and 2017/2018 (during a 1-year period). MATERIALS AND METHODS An assessment of the panoramic radiographs of 3701 patients from a Western Australian private practice identified 276 individuals demonstrating hypodontia. The location of missing teeth, age, sex, type of malocclusion, and the management strategies (space closure or opening) for each patient were noted. RESULTS Most hypodontia involved agenesis of three or fewer teeth (90%). Maxillary lateral incisors and mandibular second premolars were the most commonly missing teeth. Female preponderance was noted. When considering treatment, the odds ratio for orthodontic space opening and prosthetic replacement in 2000 was 3.266 (P value = 7e-04; 95% confidence interval [CI], 1.464-4.633) compared with patients seen in 2010 and 1.632 (P value = 7e-04; 95% CI, 0.811-2.434) compared with patients in 2017/2018. For patients demonstrating bilateral absence of maxillary lateral incisors, the odds ratio for orthodontic space opening was 3.185 (P value = 0.0215; 95% CI, 1.182-9.243) compared with counterparts with unilateral agenesis. None of the factors investigated were significantly associated with the types of treatment planned/provided for the patients with missing mandibular second premolars. CONCLUSIONS Maxillary lateral incisors and mandibular second premolars were the most commonly missing teeth. A trend away from space opening and prosthetic replacement toward orthodontic space closure was observed from 2000 to 2017/2018. This may reflect a change in attitude toward prosthetic replacement options and/or greater optimism with biomechanical strategies since the implementation of temporary anchorage devices to assist in space closure.

Abstract
Introduction: The upper lateral incisor is the most commonly missing tooth in the anterior segment. It leads to esthetic and functional imbalance for the patients. The ideal solution is the one that is most conservative and which fulfills the functional and esthetic needs of the concerned individual. Canine substitution is evolving to be the treatment of choice in most of the cases, because of its various advantages. These are special cases that need more time and effort from the clinicians due to space discrepancy in the upper and lower arches, along with the presentation of individual malocclusion. Aims and Objectives: Malocclusion occurring due to missing laterals is more complex, needing more time and effort from the clinicians because of space discrepancy, esthetic compromise, and individual presentation of the malocclusion. An attempt has been made in this article to review, evaluate, and tabulate the important factors for the convenience of clinicians. Method: All articles related to canine substitution were searched in the electronic database PubMed, and the important factors influencing the decision were reviewed. After careful evaluation, the checklist was evolved. Result: The malocclusions in which canine substitution is the treatment of choice are indicated in the tabular form for the convenience of clinicians. Specific treatment-planning considerations and biomechanics that can lead to an efficient and long-lasting result are also discussed. Conclusion: The need of the hour is an evidence-based approach, along with a well-designed prospective randomized control trial to understand the importance of each factor influencing these cases. Until that time, giving the available information in a simplified way can be a quality approach to these cases.

Orthodontic Space Closure of a Missing Maxillary Lateral Incisor Followed by Canine Lateralization. Case Rep Dent 2020; 2020:8820711. [PMID: 33274083 PMCID: PMC7683111 DOI: 10.1155/2020/8820711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Revised: 10/31/2020] [Accepted: 11/07/2020] [Indexed: 11/17/2022] Open
Abstract
Maxillary lateral incisor agenesis is the most prevalent developmental dental anomaly. The management of missing lateral incisor was either closure using canine as substitution or creation of space orthodontically for prosthetic replacement. A careful diagnosis and treatment plan are deemed essential to address the patient's needs as the spacing is present in the esthetic region. Such problem is very challenging for orthodontists, prosthodontists, and general practitioners. This case report describes the orthodontic management of a 22-year-old adult female patient with missing upper left lateral incisor tooth and upper anterior spacing by closing the space with canine lateralization and reshaping to simulate it with the lateral incisor. However, some modifications in the treatment mechanics are crucial to achieve the optimal esthetic and to improve the occlusion. Space closure with canine lateralization option seems less invasive, treatment can be completed relatively in a short period of time, and its adaptation with the facial changes throughout life without having artificial prosthesis provided other factors favoring for this option.

J Orthod Sci 2020; 9:15. [PMID: 33354541 PMCID: PMC7749456 DOI: 10.4103/jos.jos_28_19] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Revised: 09/16/2019] [Accepted: 10/09/2019] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE To determine the frequency of congenitally missing maxillary lateral incisors (LIs) and to find out its variability in relation to gender. MATERIALS AND METHODS A retrospective study was carried out between January 2017 and December 2017. Orthopantomographs (OPGs) and lateral cephalographs record search of all orthodontic adolescent patients aged 12 to 18 years were taken from the archival records of the department. Orthopantomographs helped to diagnose the presence of unilateral/bilateral maxillary lateral incisors while the ANB angle was calculated from the lateral cephalographs to divide the subjects into various skeletal malocclusions. STATISTICAL ANALYSIS USED The statistical analysis was done using the Statistical Package for Social Sciences (SPSS version 17.0). The frequencies were compared with the help of the Chi-square test. P <0.05 was considered statistically significant. RESULTS The frequency of missing upper laterals among the male patients was 0.9%, however, 2.8% of the female patients were having missing maxillary lateral incisors. Based on gender, 62.16% had a bilateral expression of missing upper laterals, 16.21% had left unilateral expression, and 21.62% had right unilateral expression. Furthermore, skeletal class I malocclusion had a prevalence of 54.16% of bilateral missing lateral incisors in upper arch as compared to 40% of left unilateral expression and 37.5% of right unilateral expression whereas in skeletal class II malocclusion, the prevalence of right unilateral expression was 37.5% as compared to bilateral expression which was 33.33%. The left unilateral expression in skeletal class II malocclusion was found to be only 20%. The highest prevalence of missing laterals in skeletal class III malocclusion was left unilateral expression which was around 40%. The prevalence of right unilateral expression was 25% whereas the bilateral absence of upper laterals in skeletal class III malocclusion was 12.5%. CONCLUSION The prevalence rate for congenitally missing upper lateral incisors in the orthodontic adolescent population aged 12 to 18 years was found to be 3.77% in the present study while females were found to have a greater percentage of agenesis of the upper lateral incisors (2.8%) as compared to the males (0.9%).

Abstract
Dental anomalies are complicating factors of orthodontic treatment, especially when 1 or more anterior teeth are affected. In this case report, a girl, aged 12.5 years with a retrognathic chin; number, size, and position anomalies of the mandibular incisors; and bilateral Class I molar relationship sought orthodontic treatment. Tooth-size ratio discrepancy was dissipated without extraction or prosthetic rehabilitation, and the initial molar relationship was maintained, as well as the straight soft tissue profile. Tipping of maxillary and mandibular incisors, crown torque of canines, restoration of anomalous incisor, and maxillary interproximal enamel reduction were key points for successful treatment. After 18 months, the orthodontic records showed stable results, excellent static and functional occlusion, and good smile esthetics and facial appearance, in addition to a high degree of patient satisfaction with the achieved results.

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
PURPOSE Resin bonded bridges (RBBs) are considered a conservative option in the management of hypodontia. This study targeted to analyze the survival of resin bonded bridges provided to patients with Hypodontia by staff and students at the Department of Restorative Dentistry, University Dental School and Hospital Cork, Ireland. It was also to determine the factors that may influence the survival of RBBs in patients with hypodontia. METHODS Forty patients with hypodontia who received 65 RBBs from 2001 to 2007 were identified and contacted to be recruited for this study. Of these, nine were not contactable, and five failed to attend. Accordingly, 26 patients (65%) participated in the study, with a total of 51 RBBs. RESULTS Of the 51 RBBs evaluated, 44 (86%) were still in situ and functional and 7 (14%) failed. The main reason for failure was repeated debonding. The effect of age, gender, the grade of operator and experience, bridge location, design of the bridge, span length and moisture control during cementation, could not be demonstrated. CONCLUSION The effect of age, gender, the grade of operator and experience, bridge location, design of the bridge, span length and moister control on RBB survival could not be demonstrated. Majority of patients with hypodontia showed satisfaction with resin bonded bridges. In replacing congenitally missing teeth in patients with hypodontia, resin-bonded bridges would be an acceptable treatment option.

Abstract
Introduction: A significant increase in the number of adults in search of orthodontic treatment has raised a new challenge for orthodontists: the need to interact with other specialties to achieve excellent results, particularly when dealing with smile aesthetics and facial balance. Several factors should be considered to respond to their demand: adequate tooth leveling and alignment, individual tooth proportions between adjacent teeth and their contralateral teeth, shape and natural appearance of each tooth and gingival architecture, which should all be in agreement with facial harmony. Maxillary or mandibular incisors congenitally missing or lost due to caries or trauma and tooth-size discrepancies (Bolton) are some of the important aesthetic challenges for an integrated orthodontic treatment. Objectives: This study describes cases that illustrate the clinical challenges of treating the anterior area, as well as the multidisciplinary strategies required for their resolution. Conclusion: The increasingly frequent multidisciplinary orthodontic treatments of complex cases seem to effectively maximize aesthetic and functional results using a combination of procedures conducted by specialists in related areas, such as Surgery, Prosthetics, Implantology, Restorative Dentistry and Periodontics.

Abstract
Orthodontic treatment of patients with unilateral and bilateral cleft palate requires an extensive interdisciplinary approach to achieve optimal functional and esthetic rehabilitation. Intervention is divided into 3 main stages: early mixed, late mixed, and permanent dentition. Treatment modalities can vary according to developmental stage, severity of cleft, and presence of other dentofacial abnormalities. This article describes the use and efficacy of different orthodontic, orthopedic, and surgical approaches at each developmental stage of unilateral and bilateral clefts, whereby the orthodontist plays a pivotal role in the different phases of growth and development of the cleft lip and the patient.

Abstract
INTRODUCTION This prospective cohort study aimed to evaluate canine substitution supported by skeletal anchorage as a viable treatment protocol for patients with maxillary lateral incisor agenesis (MLIA) and skeletal Class I or Class III. METHODS Patients (n = 30) who met the following criteria were recruited: (1) bilateral MLIA or unilateral MLIA with a riziform contralateral incisor with a planned extraction; (2) skeletal Class I or Class III; and (3) dentoalveolar discrepancy in the mandible <5 mm. The archwire sequence routine was administered, combined with a rapid palatal expander, temporary intraoral skeletal anchorage device, and intermaxillary traction with Class III elastics. The results of the cephalometric analyses, peer assessment rating indexes, and the patient's smile self-evaluation using the visual analog scale were compared between initial and final treatments. RESULTS This study indicated that closing the space in patients with Class I or Class III malocclusion by using temporary intraoral skeletal anchorage devices in the mandible, along with Class III elastics, yielded satisfactory outcomes. Proper occlusion was established by mesialization of the maxillary teeth and correction of the intermaxillary discrepancy, thereby yielding beneficial and significant cephalometric changes after the treatment. The soft tissue profile was maintained when it was harmonious before the treatment and improved posttreatment in patients in whom the profile was initially inharmonious. All occlusions improved, as evidenced by the peer assessment rating index. Smile esthetics were also enhanced after orthodontic treatment for all patients. CONCLUSIONS Canine substitution may be safely offered to patients with Class I and Class III skeletal pattern and MLIA.

Abstract
Protraction of posterior teeth to close the spaces in patients with congenitally missing maxillary lateral incisors is challenging. Mini-implants are a reliable source of anchorage for this purpose. This case report demonstrates the application of a T-bar protraction appliance with a palatal mini-implant for en masse protraction of posterior teeth into the lateral incisor space in an adolescent patient. The patient's occlusion and esthetics were significantly improved, and ideal overjet and overbite were obtained after 30 months of treatment. Follow-up records six months after the completion of the treatment displayed stable results.

Abstract
This case report describes a complex approach to orthodontic preparation for surgical treatment of a Class III facial skeletal deformity in a patient who suffered a unilateral maxilla fracture that also featured maxillary left central incisor avulsion, maxillary right central incisor extrusion, and maxillary right lateral luxation. A 12-mm negative overjet was formed by extraction of the maxillary right lateral incisor and closure of the residual space by retraction of the maxillary right central incisor, maxillary left lateral incisors, and maxillary right and left canines. Forward and impaction movement of the maxilla and retrusion and a counterclockwise turning movement of the mandible were then performed. Maxillary first premolars were reshaped to establish a maxillary canine shape, maxillary canines were reshaped to be maxillary lateral incisors, and a maxillary left lateral incisor received a central incisor crown, with a Class II molar relationship with good occlusion after 2 years of follow-up. This case was a great challenge that included complex multidisciplinary procedures, and the results indicated successful treatment of an orthodontic preparation for surgical treatment in a patient after maxillary fracture associated with dental trauma.

Abstract
Background To investigate the effect of canine edge width and height on dental esthetics in maxillary canine substitution treatment. Methods A total of 127 canine substitution treatment cases were screened and evaluated by a panel of orthodontic experts and laypersons in the pilot study. The top five subjects with the esthetically most pleasant canine substitution were included in the study, resulting in 140 computerized images displaying only the upper dentition, with different canine edge widths (0%, 12.5%, 25%, 37.5%, 50%, 62.5%, and 75% of the central clinical width) and heights (− 0.5 mm, 0 mm, 0.5 mm, and 1.0 mm vertically relative to the central incisor edge) finally used for the esthetic evaluation by 101 observers (41 orthodontists and 60 laypersons). The ordered logistic regression analysis, the univariate analysis of variance, the chi-square, and Fisher’s exact tests were used for statistical analyses. Results The most esthetic canine shape for canine substitution was found to be a shape with the edge width of 62.5% of the central incisor width and the edge height of 0.5 mm gingival to the central incisor edge (P < 0.05). The canine edge width of 50–75% and height of 0.5–0 mm gingival to the central incisor edge were generally considered to be esthetic by all observers. Orthodontists and laypersons had the same ranking on the top two most esthetic canine shapes (edge width and height 62.5% and 0.5 mm gingival; 50% and 0 mm incisal) as well as the bottom two most unesthetic canine shape (0% and 0.5 mm gingival; 75% and 1 mm incisal). Male and female observers generally had similar esthetic grades and rankings on the canine shapes (P > 0.05). Conclusions The most esthetic canine shape for canine substitution is a shape with the canine edge width of 62.5% of the central incisor width and the edge height of 0.5 mm gingival to the central incisor edge. The different collocations of the canine edge width and height affect dental esthetics of the canine during canine substitution treatment.

Abstract
Spacing between the maxillary anterior teeth is a common concern for young patients and their parents. Patients often consider a diastema to be an annoying but minor problem; they might consult their general dentists for help, or try to address the issue themselves by applying elastic "gap bands." Moreover, parents, without any informed consent, sometimes accept this erroneous method as an easy and inexpensive treatment approach. A 9-year-old boy had severe acute periodontitis involving the maxillary central incisors caused by the placement of an elastic band and its apical migration. Despite periodontal and surgical interventions, the maxillary central incisors were finally extracted, and the patient started orthodontic treatment. The orthodontic treatment plan included maxillary lateral incisor substitution to replace the lost central incisors and mesialization of the maxillary posterior dentition. An interdisciplinary approach with excellent cooperation among the orthodontist, general dentist, and other dental specialists obtained an esthetically pleasing and optimized functional result. Treating the diastema between the anterior teeth with elastic gap bands and without fixed orthodontic appliances should be avoided. Patients should seek proper orthodontic advice for even small-scale orthodontic problems to prevent catastrophic outcomes, as exhibited in this case report.

Abstract
INTRODUCTION Identification and appraisal of the outcome measures that have been used to evaluate hypodontia treatment and deliver services are essential for improving care. A lack of alignment between outcomes and patient values can limit the scope for patient-centered care. Our objectives were to identify and appraise the outcomes selected to evaluate hypodontia care. METHODS Data sources included 10 electronic databases and grey literature, searched using terms for hypodontia and its treatment methods. Study eligibility included mixed study designs to ensure comprehensive identification of outcomes, excluding case reports and case series with fewer than 10 participants and nonsystematic reviews. Participants and interventions involved people with hypodontia receiving any dental treatment to manage their hypodontia. Simulated treatment, purely laboratory-based interventions, and future treatments still in development were excluded. Research outcomes were identified and synthesised into 4 categories: clinical indicators, and patient-reported, clinician-reported, and lay-reported outcomes. No synthesis of efficacy data was planned, and consequently no methodologic quality appraisal of the studies was undertaken. RESULTS The search identified 497 abstracts, from which 106 eligible articles were retrieved in full. Fifty-six studies and 8 quality-improvement reports were included. Clinical indicators were reported in 49 studies (88%) including appearance, function, dental health, treatment longevity, treatment success and service delivery. Patient-reported outcomes were given in 22 studies (39%) including oral health-related quality of life, appearance, function, symptoms of temporomandibular dysfunction, and patient experience. Clinician-reported outcomes were limited to appearance. Variability was seen in the tools used for measuring outcomes. CONCLUSIONS There is a lack of rationale and consistency in the selection of outcome measures used to evaluate hypodontia care. Outcomes are largely clinician and researcher-driven with little evidence of their relevance to patients. There was a paucity of outcomes measuring access to care, quality of care, and cost. Evidence from hypodontia research is clinician-focused and likely to have limited value to support patients during decision making. Attempts to synthesise the evidence base for translation into practice will be challenging. There is a need for a core outcomes set with a patient-centric approach to drive improvements in health services.

Abstract
This case report describes the treatment of a severe anterior and lateral open bite combined with multiple congenitally missing teeth. A 10-year-old girl presented with an open gonial angle, absence of lip sealing, and soft tissue pogonion retrusion. She had an open bite of 8.5 mm, agenesis of the upper right and left lateral incisors and the upper left first premolar, and transverse maxillary deficiency. Nonsurgical treatment was planned aiming at controlling the vertical pattern, establishing the correct overbite, and closing the spaces on the upper arch, to provide satisfactory occlusion and facial and dental esthetics.

Abstract
This case describes a female patient with agenesis of the maxillary right lateral incisor, with her permanent canine in its position and the deciduous canine retained. Additionally, she presented with a maxillary left peg lateral incisor. To solve her functional and esthetic complaints, a multidisciplinary approach involving perio-restorative procedures was proposed. Periodontal surgeries were performed to align the gingival contour, and the restorative approach utilized ceramic veneers. At the 18-month clinical and radiographic follow-up, the treatment outcome was stable, with maintenance of the clinical results achieved and without any sign of deciduous tooth resorption.
