一、概述研究髁突运动的规律具有多方面的意义,如设计(牙合)架的髁导结构,测定下颌的正中关系位,制订咬合治疗计划,诊断颞颌关节及有关组织的某些病症等。1737年,Monro等率先以解剖学方法探讨了下颌运动问题。此后的150年中,主要是通过尸解积累了许多形态学方面的数据资料,其中一些(如“Bonwill三角学说”等)至今仍有一定意义。1889年,Luce首次在人体实测下颌运动,用照相方法从矢状面记录了髁突、下颌角、下切牙三个标志点在开闭口运动时的轨迹。近百年来,除用普通摄影法
I. Overview The study of the law of condylar movement has many meanings, such as design (occlusal) the condyle guide structure, determine the median mandibular position, the development of bite treatment plan to diagnose the temporomandibular joint and related tissues of certain diseases Wait. In 1737, Monro et al first explored the issue of mandibular motion anatomically. For the next 150 years, many morphological data have been accumulated mainly through autopsy. Some of them (such as the “Bonwill Triangle Theory”) still have some significance to date. In 1889, Luce first measured mandibular movement in the human body and recorded the trajectory of the three landmark points of mandibular condyle, mandibular angle and inferior incisor during the movement of mouth opening and closing by the method of photography from the sagittal plane. In the past century, except for ordinary photography
