Angle Class III malocclusion has been a challenge for researchers concerning diagnosis, prognosis and treatment. It has a prevalence of 5% in the Brazilian population, and may have a genetic or environmental etiology. This malocclusion can be classified as dentoalveolar, skeletal or functional, which will determine the prognosis. Considering these topics, the aim of this study was to describe and discuss a clinical case with functional Class III malocclusion treated by a two-stage approach (interceptive and corrective), with a long-term follow-up. In this case, the patient was treated with a chincup and an Eschler arch, used simultaneously during 14 months, followed by corrective orthodontics. It should be noticed that, in this case, initial diagnosis at the centric relation allowed visualizing the anterior teeth in an edge-to-edge relationship, thereby favoring the prognosis. After completion of the treatment, the patient was followed for a 10-year period, and stability was observed. The clinical treatment results showed that it is possible to achieve favorable outcomes with early management in functional Class III malocclusion patients.

“…This would work as a resistant labial crown torque. (Cancado et al, 2015;Janson et al, 2005;Janson, De Souza, Barros, Andrade Junior, & Nakamura, 2009;Valarelli et al, 2018) Some authors (Cai et al, 2014;Goldin, 1989;Janson et al, 2005;Wainwright, 1973) state that controlling the mandibular incisors lingual tipping may induce a greater alveolar bone remodeling response and additionally promoting a body movement of the mandibular incisors. Due to these, compensatory orthodontic treatment with Biofunctional prescription makes the smile more aesthetic besides causing a lower biological cost to the patient (Janson et al, 2009).…”

Introduction: Class III malocclusion has skeletal and dental components that can often impair the patient's facial appearance. Its treatment may involve orthognathic surgery or compensatory orthodontics. Case report: This case report presents a Class III malocclusion compensatory orthodontic treatment performed with the Biofunctional prescription brackets. Biofunctional prescription presents a torque value of 0° for the maxillary incisors and +10° for the mandibular incisors, which counteracts to the side effects of the use of Class III intermaxillary elastics, minimizing it, providing a more stable, aesthetic and with a healthier periodontal occlusion. Conclusion: The Class III malocclusion compensatory orthodontic treatment performed with Biofunctional prescription obtains satisfactory results, even depending on the patient collaboration with the use of intermaxillary elastics.

“…Class III malocclusion is a complex condition in terms of diagnosis and treatment planning [1,2]. In the recent years, the demand of class III patients for surgical correction of their malocclusion has greatly increased [3][4][5][6][7]. The treatment goals in correction of class III malocclusion should include achieving optimal function and esthetics, long-term stability of outcomes and selecting a surgical procedure with minimal complications.…”

Background: The primary aim of this study was to assess the esthetic profile and hard and soft tissue changes in patients with borderline class III malocclusion after maxillary advancement or mandibular setback surgery. The secondary aim was also to evaluate the patients’ face attractiveness after different surgical treatment. Materials and Methods: This observational cross-sectional study evaluated 50 patients with borderline class III malocclusion with a mean age of 29 ± 4 years treated from 2014 to 2019. They were divided into two groups based on the type of surgical treatment underwent: 13 patients were treated with mandibular setback (4 males, 9 females), and 37 patients with maxillary advancement (16 males, 21 females). Hard and soft tissue parameters were measured pre and postoperative evaluation. Frontal and profile photographs of these patients were judged by 15 orthodontists, 15 oral and maxillofacial surgeons, and 15 laypeople before and after surgery. The most and the least attractive profiles were scored 10 and 0, respectively. T-test was used to analyze normally distributed data while Mann-Whitney test for non-normally distributed data. The Kruskal-Wallis test was used to compare the esthetic judgement between the three groups of observers. Pairwise comparisons were carried out using the Mann-Whitney test. Results: Nasolabial angle, SNA, U1/NA (°), U1/NA (mm), L1/NB (°) and L1/NB (mm) were significantly different between the two groups p<0.04, p<0.001, p<0.001, p<0.005, p<0.07, p<0.08, p<0.01 respectively Orthodontists, oral and maxillofacial surgeons, and laypeople all gave a lower score to mandibular setback and higher score to maxillary advancement in terms of facial profile esthetics (P<0.001). Conclusion: Some cephalometric parameters were significantly different between the two groups. The maxillary advancement seemed to provide better results in facial profile esthetics than mandibular setback for patients with borderline class III malocclusion.
