Common Problems

Skeletal Class II malocclusion with mandibular deficiency is one of the most common problems that patients seek treatment. Adult patients with severe skeletal Class II malocclusion need orthognathic surgery for successful treatment. Bilateral sagittal split osteotomy (BSSO) is the most often preferred technique for these patients. This case report briefs about two male patient of age 24 years presented with Class II Skeletal relation, mesoprosopic facial form, horizontal growth pattern and Angle’s Class II div 1 malocclusion who were treated with Bilateral sagittal split osteotomy (BSSO) mandibular advancement. The ideal anteroposterior relation was established along with a Class I molar, incisor, canine relationship and ideal overjet, overbite and the overall facial esthetics were significantly improved. Combined surgical-orthodontic treatment aims to obtain a more harmonious facial, skeletal, dental and soft tissue relationship with an added patient self esteem.

Aim: Orthognathic surgery aims to correct facial skeletal deformities and the correct condylar positioning is very important for stable results. The aim of the present study was to verify the occurrence of changes in the postoperative condylar positioning in artificial skulls with a skeletal Class II maxillomandibular relationship submitted to bilateral sagittal split osteotomy when the method of cephalometric data transfer was used. Methods: Ten skeletal Angle class II polyurethane skulls were used with metallic markers in the articular surfaces of the temporomandibular joint and mandibular condyles. The skulls were submitted to preoperative and postoperative cone beam computed tomography before and after the bilateral sagittal split osteotomy. To verify the condylar positioning, measurements between the distances of the markers at the temporal bones and mandibular condyles were taken in the coronal and sagittal views by the DISTANCE tool of the iCat Vision software. All measurements were obtained by one examiner in the preoperative and postoperative CBCTs, tabulated and submitted to statistical analysis by the Wilcoxon test with a level of significance of 5% (p<0,05). After 15 days of the completion of the first data collection, all measurements were redone to determine the random and systematic error by the Intraclass Correlation Coefficient. Results: With the exception of the average of the lateral-medial distance (from the measurements between the medium left markers only), the averages of the anterior-posterior distances (only in the left posterior and lateral right markers) and the vertical average (only in the central markers) showed no statistically significant differences between the preoperative and postoperative distances of the metallic markers. Conclusion: Even when using the method of cephalometric data transfer, variation of the condylar positioning occurred between the preoperative and postoperative periods. This variation occurred only in a few points of the mandibular condyles.

AbstractOrthodontic-surgical treatment with the “Surgery First Approach” provides immediate facial aesthetic improvements and significantly reduces the patient's orthodontic treatment time, avoiding the transient worsening of the facial profile due to dental decompensation that occurs in surgical cases. Thus, this clinical case describes the retreatment of a 22-year-old female leukoderma patient, whose main complaint was related to the proclination of upper and lower incisors. The patient used a mio-relaxing plate for 30 days, which evidenced the skeletal mandibular deficiency and the ½ bilateral Class II malocclusion. Orthognathic surgery first approach associated with the extraction of the 4 premolars was chosen considering the patient’s aesthetic demand. The use of a mio-relaxing plate in the diagnostic stage was essential for the real diagnosis of mandibular deficiency and the technique employed made it possible to conclude the treatment avoiding aesthetic commitment, with excellent results.

ResumoO tratamento ortodôntico-cirúrgico por meio do benefício antecipado proporciona melhorias estéticas faciais imediatas e reduz de maneira significativa o tempo de tratamento ortodôntico do paciente, evitando a piora transitória do perfil facial devido à descompensação dentária que ocorre em casos cirúrgicos. Assim, este caso clínico descreve o retratamento de uma paciente com 22 anos de idade, leucoderma, sexo feminino, que apresentava queixa principal relacionada à inclinação vestibular dos dentes anteriores. Após uso de placa miorrelaxante por 30 dias, verificou-se a presença de Classe II esquelética com deficiência mandibular e ½ Classe II dentária bilateral. Considerando a demanda estética da paciente, optou-se pela abordagem ortodôntico-cirúrgica com Benefício Antecipado associada à extração de 4 pré-molares para correção da inclinação dentária anterior. O uso da placa miorrelaxante foi fundamental para o diagnóstico real da deficiência mandibular e a técnica empregada possibilitou concluir o tratamento evitando o comprometimento estético pré-cirúrgico, com obtenção de excelentes resultados.

Mandibular Retrognathism

Skeletal Class II malocclusion is attributed to maxillary prognathism, mandibular retrognathism or combination of both. In adolescent cases, the treatment includes growth modulation with headgear or myofunctional appliances. However in adults, optimum esthetic and functional efficacy can be achieved by orthodontic-surgical combination. This case report describes a 21 years old post-pubertal male with severe skeletal Class II discrepancy with normal maxilla and retrognathic mandible. The case was treated with bilateral sagittal split osteotomy (BSSO) with mandibular advancement approach. Straight profile, pleasing esthetics, bilateral Class I molar and canine relationship, normal overjet and overbite were achieved because of a combined ortho-surgical approach.

Mandibular Sagittal Split Osteotomy

Abstract Objective: To compare the treatment effects and long-term stability of the stepwise Herbst appliance and mandibular sagittal split osteotomy in skeletal Class II adult patients. Materials and Methods: Subjects comprised 16 patients in the Herbst group and another 16 patients in the surgery (mandibular sagittal split osteotomy) group. Lateral head films were taken before treatment (T0), after removal of the Herbst appliance/surgery (T1), after the fixed appliance treatment (T2), and 3 years after treatment (T3). All films were analyzed by standard cephalometrics and SO-analysis (analysis of changes in sagittal occlusion). Results: All Herbst and surgery patients were treated successfully to Class I occlusal relationships with normal overjet and overbite. Both groups showed a significant change in mandibular base advancement (SNB, SNPg, Pg/OLp), which resulted in a decrease in the ANB angle, the Wits appraisal, and facial convexity. However, the surgery group showed larger changes in the parameters mentioned above. In terms of long-term stability, both groups achieved stable results, and no significant difference occurred over time. Conclusion: Stepwise advancement Herbst appliance therapy can be used to treat borderline skeletal Class II adult patients with long-term stability.
