“…And these results were conformed to the overload of right TMJ in this study. Moreover, long‐time right chewing preference would cause facial asymmetry and defects of esthetics, even leading to asymmetry of human bodies 45 . Therefore, it is suggested to correct unilateral chewing side preference for the patients with mandibular retraction.…”

The purpose of this study is to investigate the biomechanical effect of bimaxillary osteotomies on patients with mandibular retraction. Mandibular retraction, as a typical maxillofacial deformity, and has great adverse effects on TMJ. Bimaxillary osteotomies are widely used to correct symptoms of mandibular retraction. It is necessary to understand the effect of surgery on temporomandibular disc (TMJ). Five patients with mandibular retraction and 10 asymptomatic subjects were involved in this study. Finite element models of preoperative, postoperative and control group were constructed based on the CT data. Nine sets of concentrated forces were used to simulate the muscle effect and contact method was used to simulate the interaction within the TMJs and dentitions. The results showed that bimaxillary osteotomies could effectively improve the maxillofacial morphology and alleviate the overload in TMJ. The facial asymmetry and right chewing side preference could cause imbalanced stress distributions in the TMJs and interfere the surgical treatment.

Background: Patients with mandible deviation often have idiopathic scoliosis, which might affect the result of orthodontic and orthopaedic treatment. Orthodontic treatment not only focuses on aesthetic and functional but also orthopaedic stability. A thorough examination is needed to obtain orthopaedic stability by evaluating the occlusion and posture to establish the best strategy of treatment and interdisciplinary approach. Purpose: This study was conducted to assess the correlation between mandible deviation and idiopathic scoliosis. Methods: This is a descriptive-analytic study with a cross-sectional approach. From 60 samples, 35 patients were chosen based on the inclusion criteria of the total sampling technique. Patients were referred to have skull posteroanterior (PA) and a thoracolumbar PA radiograph taken. Skull PA radiographs were analysed with Grummon’s method using the Orthovision program. Cobb’s angle analysis was used by the radiologist to analyse the thoracolumbar PA radiographs. The data gathered was then further analysed using the Spearman test and the Crosstabs test, using SPSS 23.0. Results: Correlation between mandible deviation and the severity of idiopathic scoliosis is not significant (p=0.866). The direction prevalence of mandible deviation towards Cobb’s angle is 54.3% to the right and 45.7% to the left. All patients with mandible deviation have Cobb’s angle. Conclusion: There is no correlation between mandible deviation and the severity of idiopathic scoliosis. However, many cases showed that the direction of mandible deviation and of idiopathic scoliosis is the same.
