目的:评价再定位咬合板治疗深覆伴颞下颌关节盘可复性前移位的临床疗效。方法:选择25例深覆伴颞下颌关节盘可复性前移位患者戴用再定位咬合板治疗,治疗期限为6个月,治疗完成后随访6个月,行关节常规检查并拍X线片,并行颞下颌关节核磁检查,评价治疗效果。结果:经过治疗,23例弹响患者中16例(69.56%)弹响完全消失,2例(8.70%)弹响减轻,总有效率78.24%,11例疼痛患者中6例(54.55%)疼痛消失,3例(28.18%)疼痛明显减轻,总体有效率为82.72%,4例张口受限患者中2例(有效率50.00%)转为正常,1例(有效率25%)即张口度改善大于0.5cm,总体有效率75.00%。结论:再定位咬合板对治疗深覆伴颞下颌关节盘前移位患者具有较好的疗效。
OBJECTIVE: To evaluate the clinical effect of repositioning occlusal plate in the treatment of deep overburden accompanied by the anterior displacement of temporomandibular joint disc. Methods: Twenty-five patients with deep superficial ridges and temporomandibular joint disc reconstruction were retrospectively treated with repositioning bite plates. The treatment period was 6 months. After the treatment was completed, the patients were followed up for 6 months. The joints were routinely examined and X Line, parallel to the TMJ MRI examination to evaluate the therapeutic effect. Results: After treatment, 16 cases (69.56%) of 23 cases snapping completely disappeared, 2 cases (8.70%) snapping reduced, the total effective rate was 78.24%, and 6 cases (54.55%) of the 11 cases were painful 3 cases (28.18%) were relieved pain, the overall effective rate was 82.72%, 2 cases (effective rate 50.00%) of 4 cases of limited mouth opening were changed to normal, 1 case (effective rate 25% Greater than 0.5cm, the overall efficiency of 75.00%. Conclusion: Repositioning occlusal plate has a good curative effect in the treatment of deep discordance with temporomandibular joint disc displacement.
