摘　　要：目的:通过分析比较不同方案治疗前后髁状突旋转角度与疗效的相关性,探讨将髁状突的旋转角度作为不同治疗方案选择标准的可行性。方法:将咬合重建患者18例随机分为两组,分别采取过渡性修复后永久性修复和直接永久性修复两种治疗方案,测量治疗前后髁状突的旋转角度、颞下颌关节紊乱指数及肌电活动变化,分析髁状突旋转角度与疗效的相关性。结果:采取过渡性修复后永久性修复方案和髁状突旋转角度不超过3°采取直接永久性修复治疗方案时,治疗后各项指标均较治疗前相比有明显改善(P<0.05);而当髁状突旋转角度超过3°采取直接永久性修复治疗方案时,治疗前后差别无统计学意义(P>0.05)。结论:髁状突的旋转角度与咬合重建不同治疗方案的疗效存在相关性。当髁状突旋转超过3°时,建议永久性修复前先进行过渡性修复。Objective： To discuss the possibility of using the condyle rotation angle as a inclusion criteria to choose dif- ferent treatment plans by analyzing the dependability of condyle rotation angles and different curative effects by different therapeutive regimens. Methods： 18 patients wfio need occlusal reconstruction were divided into two groups randomly, one group got treatment including a transitional therapy before the permanent therapy, and another got only a permanent thera- py. Every patient was got examinations of the condyle rotation angles, CMI and myoelectricity changes before and after therapies. Finally the datas were made statistics analyzing. Results： The dates got from the patients who got treatment including a transitional therapy before the permanent therapy and a !Sermanent therapy only （condyle rotation angles≤3°） before and after therapies were different,and the differences possessed statistical significance （P〈0.05）, while there were no statistical significance of the dates got from the patients who got a permanent therapy only （condyle rotation angles 〉 3°） before and after therapies（P〉0.05）. Conclusions： There are correlations of condyle rotation angles and different curative effects of occlusal reconstruction by different therapeutic regimens, a transitional therapy before the permanent therapy is necessary when the condyle rotation angle exceeds 3°.
