对颞下颌关节的研究方法进行了综述。为这项研究设计了一种特殊的头部保持器，它允许关节的真实侧向曝光，连续的X线照片易于精确测量，并曝光足够大的区域，包括关节，牙齿和某些定向参考平面。观察到窝大小和髁突大小之间的关系存在相当大的变化。在颞下颌关节的研究中，如果不能找到一种既能反映下颌骨在静止位又能反映其在闭合位的真实位置的方法，就不能对颞下颌关节及其功能进行全面而正确的分析。这项研究的证据表明，太多的重点放在过去的髁突窝关系的力学。罗宾逊（Robinson，1946）认为肌肉是唯一负责下颌复杂运动的因素，这一观点似乎得到了这项研究的证实。
Previous methods of study of the temporomandibular joint are reviewed. A special head holder was devised for this study which permits true lateral exposures of the joint, successive X-ray photographs susceptible to accurate mensuration, and exposure of a field large enough to include joint, teeth, and certain orienting planes of reference. Considerable variation in the relation between size of the fossa and size of condyle was noted. It seems that a complete and correct analysis of the temporomandibular joint and its functions can not be made unless a method is employed in its study which reveals the true position of the mandible in both its resting and closed positions. The evidence of this study indicates that too much emphasis has been placed in the past upon the mechanics of condyle-fossa relationship. The opinions expressed by Robinson (1946) that the muscles are solely responsible for the intricate movements of the jaw seem to be proven by this study.
