目的：研究不良修复体导致颞下颌关节紊乱病（TMD）的因素。方法选择199例佩戴不良修复体并导致 TMD 的患者，根据不良修复体引起的症状分为3组：咬合垂直距离改变组、咬合紊乱组、基牙损伤组。治疗后随访12个月，通过分析 TMD 治疗的有效性，探讨不良修复体引起 TMD 的因素。结果咬合垂直距离改变、咬合紊乱、基牙损伤3组治疗有效率分别为89．55％、89．06％、32．35％，基牙损伤组治疗有效率与其他2组比较，差异均有统计学意义（P＜0．05），提示咬合垂直距离改变和咬合紊乱更容易导致 TMD 。结论不良修复体所导致的上下颌垂直距离改变、咬合关系紊乱与基牙损伤与颞下颌关节滑膜炎、关节盘移位及骨关节病存在相关性。

Objective To investigate the factors of temporomandibular disorders(TMD) caused by the improp‐er dental prosthetic restoration .Methods 199 cases of improper dental prosthetic restoration and TMD were selected and divided into 3 groups according to the symptoms caused by improper dental prosthetic restoration :occlusion ver‐tical distance change ,occlusion disorders and abutment tooth injury .The follow up after treatment lasted for 12 months .The factors of improper dental prosthetic restoration caused TMD were investigated by analyzing the TMD treatment effectiveness .Results The treatment effective rates in the occlusion vertical distance change group ,occlu‐sion disorders group and abutment tooth injury group were 89 .55% ,89 .06% and 32 .35% respectively ,the effective rate had statistical difference between the abutment tooth injury group with the other two groups(P< 0 .05) ,which prompting that occlusion vertical distance change and occlusion disorders could more easily lead to TMD .Conclusion The occlusion vertical distance change ,occlusion disorders and abutment tooth injury caused by improper dental prosthetic restoration have the correlation with temporomandibular joint synovitis ,disc displacement and osteoarthro‐sis .
