In 40 temporomandibular disorders (TMD) patients and 12 healthy subjects, who had nearly complete natural dentition, numbers and distribution of occlusal contact areas were examined at intercuspal position (ICP) and at the extremely light tooth-tapping position with the aid of electromyographic biofeedback, which called as the physiologic centric position (PCP). The distribution was expressed as an asymmetry index (AI) : the difference between the number of occlusal contact areas on the right side and those on the left side divided by the total number of contact areas on dental arch. The mean number of occlusal contact areas at PCP in the patients before treatment was significantly less than that in the healthy subjects and the patients after treatment by means of selective occlusal adjustment. The mean AI in the patients before treatment was significantly larger than that in the healthy subjects and the patients after treatment, although AIs at ICP were not different significantly among them. In conclusion, conventional methods of occlusal examination at ICP defined with mechanical property of occlusion were not suitable for evaluation of occlusion in TMD patients. Balanced distribution of occlusal contact areas on dental arches can be a key of occlusion concerned with TMD.

应用肌电生物反馈技术，对40例颞下颌关节紊乱病（TMD）患者和12例正常人在牙尖交错位（ICP）和极轻叩齿位（PCP）时的咬合接触区数目和分布进行了研究。结果显示，治疗前PCP患者的平均接触面积明显小于健康对照组和选择性调牙合治疗后患者的平均接触面积，差异有统计学意义。治疗前患者的平均AI显著大于健康人和治疗后患者，但ICP时的AI在他们之间无显著差异。因此，传统的以咬合力学性质为标准的ICP咬合检查方法不适合于TMD患者的咬合评估。牙弓上咬合接触面积的平衡分布可能是TMD患者咬合关系的关键。
