临床弹响消失位作为调位垫治疗位的研究

To probe into the practicability of using the jaw position of eliminating TMJ clicks as the therapeutic position of repositioning splint

目的 研究临床以弹响消失位作为调位垫治疗位的可行性 ,进一步探讨调位垫的治疗机理。方法 2 5名接受调位垫治疗的可复性盘前移位患者 ,以弹响消失位制作调位垫 ,在关节造影下验证盘 /突位置改变 ,观察临床治疗效果。结果 2 5名患者中 ,19人盘 突完全复位 ,5人复位不全 ,1人未复位 ,治疗过程中盘 突复合体运动协调。治疗后关节区舒适 ,开口型改变 ,关节弹响减轻。结论 以临床弹响消失位作为调位垫的治疗位是可行的。调位垫通过改变盘 突位置关系 ,改善盘 突复合体运动的协调性 ,有利于盘后区的机化和盘后带改建 。

Objective To evaluate that it was practicable to use the jaw position of eliminating TMJ clicks as the therapeutic position of repositioning splint and to probe into the therapeutic mechanism of repositioning splint. Methods 25 patients with reducible disc displacement were treated with repositioning splint. The therapeutic jaw position was the position without TMJ clicking, then verified by Arthrography. The treatment effect was observed.Results Among 25 cases, 19 discs were completely recaptured, 5 incompletely recaptured, 1 not recaptured. Once the splints inserted, the movements of disc condyle complex were smooth. After treatment finished, the opening types were improved, the clicks were lessened. Conclusions It's practicable to use the jaw position of eliminating clicks as the treatment jaw position of repositioning splint. The therapeutic mechanism of repositioning splint may be that it altered the relationship of disc and condyle and improved their movement. That was favorable to fibrize the retrodiscal tissue and to strengthen the posterior band of disc.
