摘要
目的:观察固定桥治疗重度磨损颞颌关节紊乱病(TMD)患者后髁状突位置的改变。方法:对12例重度磨损伴颞下颌紊乱病的患者行固定桥修复,恢复其正常的垂直距离,于治疗前后行双侧闭口薛氏位拍片,进行关节间隙测量。对治疗后的患者进行至少3年的随访。结果:固定桥治疗前关节前,上,后间隙分别为1.94mm,3.07mm,2.56mm;固定桥治疗后关节前,上,后间隙分别为1.88mm,2.22mm,2.48mm。其中关节前间隙,后间隙改变有统计学意义(P<0.05,P<0.01)。结论:固定桥修复重度磨损伴颞下颌紊乱病的患者,恢复了其正常的垂直距离,恢复了髁状突在关节凹中的正常位置。
Objective： To observe the changes of mandibular condyle position before and after fixed bridges in heavy abrison and TMD patients. Methods： Fixed bridges were used to treat 12 patients with heavy abrison and TMD when normal vertical dimension were restoration. The Schuller＇s positional radiographs were taken before and after treatment. Joint spaces between the glenoid fossa were measured on the centric occlusion. Results： The mandibular condyle position were displaced 1.94mm, 3.07mm, 2.56mm before treatment. And after treatment were 1.88mm, 2.22mm, 2.48mm. There was statistical differences in the changes of anterior and postern spaces. （ P 〈 0.05, P 〈 0.01 ）. Conclusion： The patients with heavy abrison and TMD treated with fixed bridges could obtain normal vertical dimension. The mandibular condyle positions could be moved into suitable position.
