Development of the diagnostic system for occlusion in prosthetic treatment

为了在义齿治疗后保持良好的口腔状态，义齿必须在功能上与口腔颌面系统相协调。口腔功能，包括咀嚼，是通过咬合来完成的。因此，如果咬合接触适当，我们可以有效地发挥口腔颌面功能。另一方面，咬合不协调会导致颞下颌关节紊乱病和牙周病。咬合和谐对于维持咀嚼系统的健康和功能能力是极其重要的。本研究旨在开发咀嚼效能诊断系统。我们使用Mortion Capture System Vicon512测量了咀嚼过程中面部的多个参考点。可以使用主成分分析来估计咀嚼效率。

In order to maintain good oral conditions following prosthetic treatment, the prosthesis must be functionally harmonized with the stomatognathic system. Stomatognathic function, including mastication, is performed by occlusion. Therefore, if the occlusal contact is suitable, we can perform stomatognathic function efficiently. On the otherhand, occlusal disharmony can give rise to temporomandibular disorders and periodontal disease. Occlusal harmony is extremely important for maintaining the health and functional capacity of the masticatory system. The purpose of this study was to develop the diagnostic system for masticatory efficiency. We measured multiple reference points on the face during mastication using mortion capture system Vicon 512. It is possible to estimate of masticatory efficiency using the principal component analysis.
