下顎限界運動と最大下顎開閉口運動による顎機能診断

Abstract

The purpose of this study was to investigate useful parameters and establish an evaluation standard for diagnosis of stomatognathic function.The details for a total of 21 patients are as follows:1. Persons having neither subjective nor objective symptoms but having individual normal occlusion for stomatognathic (12 subjects).2. Persons who could be classified according to disease type classification of TMD of the Japanese Society for Temporomandibular Joint and judged as type I and type II (9 subjects).Mandibular border movement and maximal opening and closing movement of these subjects were examined.As a result, form-like resemblance of speed curve changed with the elapse of time during maximal opening and closing movement, that is, Kendall's coefficient of concordance suggested that several levels of reproducibility can be quantitatively expressed because 3-repetition movement may become a useful index to make proper diagnosis of abnormality stomatognathic function (type I and type II of disease type classification of TMD of the Japanese Society for Temporomandibular Joint).
