Maxillary lateral incisor agenesis is a condition that significantly compromises smile esthetics, which is particularly worrying in young patients. This article shows how the combination of non-invasive treatments and current restorative options may improve clinical outcomes following orthodontic treatment for symmetric and asymmetric maxillary lateral incisor agenesis and microdontia. Teeth were treated with conservative resin restorations in three separate cases: two of congenitally missing maxillary lateral incisors (i.e., unilateral and bilateral) and one of microdontia. After presenting the clinical results, this article summarizes how bleaching, enameloplasty, and bonding with composite resin can enhance esthetics and functions following orthodontic space closure. The cases reveal that carefully planned, methodically executed orthodontic and restorative approaches can achieve predictable, esthetic outcomes that will improve the patient’s self-esteem with a minimally invasive solution.

ABSTRACT Objective: The purpose of this study was to determine the perception of trained dental professionals and laypersons toward the esthetic impact of variations in the vertical position, width, and gingival height of the maxillary lateral incisor. Materials and Methods: The present study analyzed the perspective of smile photographs by dental professionals such as “fifty orthodontics and fifty general dental practitioners (GDPs)” as well as fifty laypersons, consisting of an equal number of male and female participants. Photographs edited to depict alteration of golden proportion, incisal length, and gingival height of lateral incisor. SPSS software was used to analyze the data and determine the significant difference within all the participants, at 0.05% level (95% confidence interval). Results: There was no significant difference in ranking between the genders. Golden proportion of 62%–67% were ranked the highest by orthodontists, whereas GDPs and laypersons preferred 67%. Regarding gingival display, corrected height of −0.5 and −1 mm received highest ranking from all the three groups. In case of lateral incisal length, −0.5 mm was ranked highest by laypersons, in contrast to −1 mm by orthodontists and GDPs. Conclusion: Specific differences were observed in the ranking of smile esthetics by health-care professionals and laypersons. Golden proportion of 62% and 67% were ranked the highest by orthodontists, whereas GDPs and laypersons preferred 67%. Corrected gingival height of −0.5 and −1 mm received highest ranking from all the three groups. In case of lateral incisal length, −0.5 mm was ranked highest by laypersons, in contrast to −1 mm by orthodontists and GDPs.

ABSTRACT Aim This case report aimed to present an orthodontic mechanic alternative for space opening in a patient missing maxillary lateral incisors, using miniplates as anchorage, associated with self-ligating brackets. Background Dental agenesis affects the population causing esthetic and functional damages. The prevalence of missing maxillary lateral incisors should be considered for its significant rate and negative impact on smile esthetics. Case report This treatment was chosen based on the presence of balanced facial pattern, large canine anatomy, the need to improve dental occlusion to prevent further wear, and patient's esthetic complaint. To obtain the results, upper third molars were extracted, and two miniplates were installed to distalize the upper arch with no need for patient compliance or auxiliary devices. Self-ligating brackets were used to reduce friction on posterior teeth, thus facilitating movement with light force application. At the end of 19 months, the patient presented with class I good overbite and overjet, and adequate space for implant and prosthetics; also, good facial esthetic was maintained. Conclusion When indicated, space opening may provide excellent esthetics and functional results, and even more predictable results when skeletal anchorage miniplates are used to distalize all posterior teeth. Clinical significance Considering the high level of esthetic and functional compromise caused by dental agenesis, the technique hereby described represents a viable mechanic alternative within orthodontic possibilities.

Congenitally Missing

The congenital absence of one or more maxillary lateral incisors poses a challenge to effective treatment planning for general dentists and dental specialists. An evaluation of anterior smile esthetics must include both static and dynamic evaluations of frontal and profile views to optimize both dental and facial appearance. This article presents a case with canine substitution treatment to replace a missing maxillary lateral incisor combined with the extraction of two mandibular lateral incisors and a small maxillary lateral incisor. Both the patient's occlusion and facial appearance were significantly improved after orthodontic treatment.

Maxillary Lateral Incisor

Summary Background The maxillary lateral incisor is one of the teeth most likely to suffer agenesis, resulting in spacing between the central incisor and the canine. Objective To compare maxillary lateral incisor agenesis with space closure treatment versus non-treatment based on measurements of the self-perceived oral-health-related quality of life (OHRQoL) and self-esteem of the participants. Subjects and methods A total of 44 people, aged 17–49 years, with missing lateral incisors were randomly assigned to two groups (n = 22 in each)—a treated group in which the space was orthodontically closed (TG) and a control group that remained untreated (CG). Randomization was performed by a researcher who was not involved in the clinical part of the study. The outcomes were assessed using the Oral Health Impact Profile and Rosenberg’s Self-Esteem Scale, which were applied before (phase 1) and after (phase 2) the orthodontic treatment in the TG, and at baseline (phase 1) and 12 months after (phase 2) in the CG. All the data were blindly evaluated, supporting the single-blinded design of the study. Results All participants finished the randomized controlled trial, and the demographic characteristics were similar between the groups. In phase 1, the levels of self-esteem and OHRQoL at baseline were similar (P = 0.079, P = 0.693, respectively). In phase 2, the self-esteem scores of the CG decreased and the OHRQoL increased (P = 0.005, P < 0.001, respectively), while self-esteem increased in the TG and the OHRQoL decreased (P < 0.001). The CG had lower scores than the TG for self-esteem, but the opposite was observed for OHRQoL (P < 0.001). Limitations Information bias may have occurred. Since the questionnaires could not have been applied at the same time in both groups, the time difference between the two assessments may have led to random and systematic error. Conclusions The spacing resulting from missing maxillary lateral incisors had a negative impact on the OHRQoL and self-esteem of the participants, while orthodontically closing those spaces had a positive impact on those aspects. Clinical trial registration This study was not registered. Protocol The protocol was not published before trial commencement.

Research Analysis

Introduction:Cleft lip and palate are craniofacial anomalies highly prevalent in the overall population. In oral clefts involving the alveolar ridge, variations of number, shape, size and position are observed in maxillary lateral incisors. The objective of this manuscript is to elucidate the embryonic origin of maxillary lateral incisors in order to understand the etiology of these variations.Contextualization: The hypothesis that orofacial clefts would split maxillary lateral incisor buds has been previously reported. However, recent studies showed that maxillary lateral incisors have dual embryonic origin, being partially formed by both the medial nasal process and the maxillary process. In other words, the mesial half of the lateral incisor seems to come from the medial nasal process while the distal half of the lateral incisor originates from the maxillary process. In cleft patients, these processes do not fuse, which results in different numerical and positional patterns for lateral incisors relating to the alveolar cleft. In addition to these considerations, this study proposes a nomenclature for maxillary lateral incisors in patients with cleft lip and palate, based on embryology and lateral incisors position in relation to the alveolar cleft.Conclusion:Embryological knowledge on the dual origin of maxillary lateral incisors and the use of a proper nomenclature for their numerical and positional variations renders appropriate communication among professionals and treatment planning easier, in addition to standardizing research analysis.
