Development of an integrated analyzing system using six-degree of freedom jaw tracking device and non-cont three-dimensional shape measuring system

以圆柱形和二次多项式曲线为数学模型，对JKN-1咬合离合器进行了改进，建立了JKN-1咀嚼运动与非CONT三维形状测量系统的综合分析系统。最初设计的离合器(OrthoClutch-2)被开发出来，并与正畸粘合剂(FujiOrthoLC，GC)一起使用。用新型离合器帮助闭合嘴唇，可以自然地记录咀嚼运动。用于定量分析咀嚼过程中咬合相附近的颌骨运动。综上所述，利用六自由度颌骨跟踪器和非接触式三维形状测量系统开发了一套咀嚼运动自动分析系统，用于临床正畸领域的诊断。

The purpose of this study was to develop an integrated analyzing system chewing movement with six-degree of freedom jaw tracking device (JKN -1, Tokyo Shizaisha) and non-cont three-dimensional shape measuring system (VMS-250R, UNISN Co.).To analyze the occlusal shape in three-dimensional space, cylindrical and quadratic polynomial curve were used as mathematical models.Commercially available clutch of the JKN-1 was improved for subjects with malocclusions. Originally designed clutch (OrthoClutch-2) was developed, and used with orthodontic adhesive (FujiOrthoLC, GC). Chewing movement can be naturally recorded with the new clutch that helps closure of the lips.Original software program was developed by software language (Microsoft Visual Basic 6, Microsoft Co.) for quantitative analysis of jaw movement near the occlusion phase during mastication.In conclusion, by chewing movement automatic analyzing system was developed with the six-degree of freedom jaw tracking device and non-contact three-dimensional shape measuring system for diagnosis in the field of clinical orthodontics.
