Six rabbits with unilateral occlusal splints on the mandibular left molars for one month, three months or five months were examined to study the ultrastructure of the surface of the temporomandibular joint. Four rabbits were used as control. The results showed that the surface layer of the disk and articular cartilage were damaged. Severe fibrillation with sheets of fibers, collagen fibrils and collagen bundles inside fissures and craters were observed. These changes were seen in all rabbits with occlusal trauma and also in control rabbits for five months. The findings suggested that occlusal trauma could result in degenerative changes of the temporomandibular joint.
对六只下颌左磨牙佩戴单侧咬合夹板一个月、三个月或五个月的兔子进行检查，以研究颞下颌关节表面的超微结构。以四只兔子作为对照。结果显示，关节盘和关节软骨的表层受损。观察到严重的纤维性变，裂隙和凹坑内有片状纤维、胶原原纤维和胶原束。在所有有咬合创伤的兔子以及作为对照的五只兔子中均观察到这些变化。研究结果表明，咬合创伤可导致颞下颌关节的退行性改变。
