An individualized technique for radiography of the temporomandibular joint utilizing oblique lateral transcranial projection is described. The patient is fixed in a cephalostat and the central ray directed through the horizontal long axis of the condyle. The information yielded when applying the individualized technique has been compared with that yielded from a standard technique and tomography. The plane of sectioning for tomography was oriented perpendicular to the horizontal long axis of the condyle. The material comprised radiographs from 30 joints. The condyle to fossa relation was studied as well as the occurence of structural changes. Neither the individualized technique nor the standardized technique gave an accurate picture of the condyle to fossa relation when compared to tomography. However, the individualized technique tended to give the same result as tomography more often. Tomography revealed the greatest number of structural changes (66) followed by individualized technique (47) and standard technique (19). Most changes were noted exclusively in one projection. A combination of individualized technique and tomography revealed more changes than a combination of tomography and standard technique.
本文描述了一种利用斜侧经颅投影进行颞下颌关节X线摄影的个体化技术。患者固定于头颅固定架上，中心线通过髁突的水平长轴。将应用个体化技术所获得的信息与标准技术及体层摄影所获得的信息进行了比较。体层摄影的断层平面垂直于髁突的水平长轴。材料包括30个关节的X线片。研究了髁突与关节窝的关系以及结构变化的发生率。与体层摄影相比，个体化技术和标准化技术均未准确显示髁突与关节窝的关系。然而，个体化技术更倾向于与体层摄影给出相同的结果。体层摄影显示的结构变化数量最多（66处），其次是个体化技术（47处）和标准技术（19处）。大多数变化仅在一种投影中被发现。个体化技术与体层摄影相结合所显示的变化比体层摄影与标准技术相结合更多。
