1902年Christensen用前伸记录法首次确定髁突矢状运动的倾斜角度,1908年Gysi发明用描绘法使髁突的矢状运动成为图象。晚近的技术如电影摄影术,活动荧光摄影法和电子方法,也用于现今的研究。但更多的研究设计是有关生理性咀嚼运动方面的资料,而关于功能紊乱患者的咀嚼运动的资料却很少得到。本研究试图取得有关颞颌关节弹响的资料。目前,弹响的机制仍处于假说阶段,一般认为是关节盘起着重要的作用。当关节盘摘除后即不再发生弹响(Boman,1947)。由于关节盘是结缔组织构成,除非用关节X
In 1902, Christensen first identified the tilt angle of the sagittal sagittal motion using the extensional recording method. In 1908, Gysi invented the sagittal motion of the condyle to become an image by the tracing method. Recent techniques such as cinematography, active fluorography and electronic methods are also used in current research. However, more research designs are based on information on physiological chewing movements, whereas information on chewing movements in dysfunctional patients is rarely available. This study attempts to obtain information about the temporomandibular joint snapping. At present, the snapping mechanism is still in the hypothetical stage, it is generally believed that the disk plays an important role. Snapping no longer occurs when the disc is removed (Boman, 1947). As the articular disc is composed of connective tissue, unless the joint X
