부정교합에 의한 비정상 저작운동 시 턱관절에서의 생체역학적 특성 변화

다국어 초록 (Multilingual Abstract)

The surgical intervention for temporomandibular joint is required to patients who suffer an inflammation and pain by malocclusion. However, it had not sufficient the information of muscular motion and were not considered for biomechanical variables. The aim of this study was to identify the change of biomechanical characteristic in the temporomandibular joint during masticatory movements by normal occlusion and malocclusion. To measure the biomechanical characteristic of temporomandibular joint for masticatory movements (Open-Close, Protrusion, Slide-to-Slide) at malocclusion, a three-dimensional(3D) motion capture system (Vicon Motion Systems Ltd.;) and multibody dynamic (Anybody 7.3) was used. In this study, we had confirmed that the reaction force, moment, and motion for temporomandibular joint are more relatively higher in all of the masticatory movement when it is malocclusion. This result may be meaning that the surgical intervention needs to consider biomechanical variables.
