摘　　要：目的观察颞下颌关节盘可复性前移位患者的咬合接触特征并比较其与正常人的差异。方法采用T-ScanⅡ咬合分析系统记录30名颞下颌关节盘可复性前移位患者和30名正常人于牙尖交错位和后退接触位时的咬合接触信息并进行统计分析。结果颞下颌关节盘可复性前移位患者在牙尖交错位可出现力中心较大的偏移、两侧接触点不平衡、两侧力不对称、弹响侧接触点数目多于非弹响侧;在后退接触位颞下颌关节盘可复性前移位患者双侧接触点数目有显著差异,单侧接触者显著增多。结论颞下颌关节盘可复性前移位患者咬合接触情况与正常人有显著的差异,提示咬合因素与颞下颌关节盘可复性前移位有密切的关系。Objective To investigate and compare the occlusal contact of of anterior disc displacement with reduction of temporomandibular joint （ADDR） patients with that of normal people. Methods The information of ocelusal contact of intercuspal position and retruded contact position was analyzed using T-Scan II system, including 30 of normal people and 30 cases of ADDR patients. Results The patients of ADDR had ocelusal force centre excursion, bilateral occlusion imbalance and asymmetry of bilateral ocelusal force in ICP. And data showed more contact points appeared in the side of clicking. In RCP a significant difference was found between the numbers of contact points of two sides and more unilateral occlusal contact had been found in patients of ADDR. Conclusion There was signifcant difference between the occlusal contact of ADDR patients and that of normal people, which indicated the occlusal factor plays an important role in the development of ADDR.
