Abstract
This study investigated the effect of SSRO on TMJ biomechanics in mandibular deformity patients. Using 3D models with anterior incisal muscle forces and condyle-disc-fossa contact simulation, TMJ stress in 10 patients before and after SSRO was compared to that in 10 controls. Both pre- and postoperative condylar principal stresses (max/min) were significantly higher than those in controls (p<.05). Preoperative TMJ contact stress showed asymmetric distribution in patients with mandibular deviation, which was alleviated postoperatively. SSRO alleviates abnormal TMJ stress in mandibular deformities, and temporomandibular disorders correlate with TMJ stress distributions.
期刊介绍:
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
