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.

为了在修复治疗后保持良好的口腔条件，修复体必须与口颌系统功能协调。包括咀嚼在内的口颌功能是通过咬合来实现的。因此，只要咬合接触适当，就能有效地发挥口颌功能。另一方面，咬合不协调可引起颞下颌关节紊乱病和牙周病。咬合关系的和谐对于维持咀嚼系统的健康和功能能力是极其重要的。本研究旨在建立咀嚼效能的诊断系统。我们使用运动捕获系统Vicon 512测量了咀嚼期间面部的多个参考点。用主成分分析法估计咀嚼效率是可行的。
