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.

“…According to (Janson et al, 2008;Kumar and Sneha, 2016), in a case of skeletal class III malocclusion with temporomandibular pain, a segmental LeFort I Osteotomy procedure gave good results with relief of TMD pain. (Arpornmaeklong et al, 2003;Patturaja and Pradeep, 2016), recommends segmental osteotomy procedures to enhance the occlusal results postoperatively.…”

Maxillary skeletal deformities can occur in all three planes and are corrected by orthognathic surgery. Osteotomies form the basis for orthognathic surgeries. One of the most commonly used osteotomy techniques for maxillary skeletal deformities is the LeFort osteotomy. The aim of this study was to compare the application of One Piece LeFort Osteotomy and Segmental Osteotomy procedures in the treatment of maxillary skeletal deformities. The institutional study involved analysis of case sheets of patients who underwent surgical correction of maxillary skeletal deformities in the stipulated time frame and assessment based on the parameters: Demographic data, type of cephalometric analysis, cephalometric values, type of skeletal deformity, and technique of Osteotomy. Statistical analysis was calculated by chi-square test. A p-value<0.05 was considered significant. Maxillary skeletal deformities were more prevalent among females (60%) than males (40%). Anterior maxillary segmental osteotomies were more commonly performed (60%), followed by LeFort 1 osteotomy (26.7%). The prevalence of posterior osteotomy technique was 13.3%. A statistically significant association was revealed between the type of skeletal malocclusion and technique of Osteotomy used, with a p-value of 0.008<0.05. The type of malocclusion dictates the technique of Osteotomy is used. In a skeletal Class II, segmental malocclusion procedure was more preferred for maxillary deformities.

“…Furthermore, because the dental alveolus is expanded by the tipping movement of the teeth orthodontically, there are risks such as relapse after surgery, root exposure, and retraction of the buccal gingiva. 1 , 2 In the expansion of the maxillary bones, however, the surgical stress and patient burden is obviously greater than in simple 1-jaw surgery when a combination of procedures, such as segmental Le Fort I osteotomy 3 and mandibular surgery, is performed. 4 , 5 …”

Background:The aim of the present study was to evaluate the treatment of patients developing a transverse jaw width discrepancy who exhibited class III malocclusion and/or facial asymmetry by a combination of mandibular constriction (MC) and intraoral vertical ramus osteotomies (IVROs).Subjects and methods:In a retrospective study, functional results, postoperative complications, and skeletal stability were analyzed for all the patients who had undergone MC and IVRO, with more than 2 years of follow-up. A mandibular midline osteotomy for constriction with lag screw technique and IVROs was used for MC and setback.Results:Sixteen patients were included in the present study. The average degree of MC was 6.34 mm. Both the occlusal relationship and facial appearance in all patients were significantly improved by the surgical orthodontic treatment, with no harmful clinical symptoms. In addition, our original MC using lag screw technique provided the most reliable results in terms of skeletal stability.Conclusions:This study showed that MC using lag screw technique gives a very stable mandibular width constriction, and the combination of MC and IVROs offers a promising treatment alternative for patients with mandibular prognathism developing a transverse jaw width discrepancy.
