采用250帧/S和500帧/S的高速摄影技术，对5例有点击和4例无点击的颞颌关节尸检标本进行了高速摄影。通过摘除关节囊和关节盘的外侧部分来显示关节间隙。在无卡爪的关节中，观察到髁突和关节盘运动均匀、光滑。在有点击的关节中，勾画出与点击相关的关节盘和髁突的快速运动。在4个相互点击的关节中，在关节突滑过椎间盘后脊后击中颞部的瞬间记录了点击。在有点击的第5个关节中，与点击相关的是髁突与关节盘之间的协调运动。在解剖时，所有关节都显示出颞骨和下颌骨的形态偏离。
High-speed cinematography using 250 frames/s and 500 frames/s was performed on five temporomandibular joint (TMJ) autopsy specimens with clicking, and four without. The joint compartments were visualized by removal of the lateral part of the capsule and disc. In joints without clicking, even and smooth movement of condyle and disc was observed. In joints with clicking the rapid movement of disc and condyle in association with clicking was delineated. In four joints with reciprocal clicking, the clicking was registered at the instant the condyle hit the temporal component after having slipped over the posterior ridge of the disc. In the fifth joint with clicking, movement between condyle and disc was coordinated in association with clicking. At dissection all joints demonstrated deviation in form of both the temporal and mandibular components.
