摘要
作者采用钛合金人工关节凹治疗颞颌关节强直。该方法解决了其它方法所产生的因去骨过多而致下颌偏位、开合、以及填隔物固定不佳而致脱位等缺点,具有手术简单,对机体创伤小,有良好的固定装置,又可免除切取自体移植料而给病人造成痛苦的优点。通过对一例双侧颞颌关节骨性强直病人行钛合金人工关节凹置换治疗,经1.5年的观察随访,开口度为2.5cm,达到理想效果。
A patient with bilateral temporo-mandibular joint ankylosis was treated with Ti-alloy artifical articular concavity. One year after the treatment it was found that the patient's open mouth width was. 2.5 centimeter, with satisfactory result. This method is easy to operate and to fix, with less damage, and furthermore it's unnecessary to cut autografting materials. At same time,it avoid mandibular deviation or open bite caused by cutting too much bone by other methods and dislocation resulting from bad fixing of interposed foreign material.
