错矫治治疗颞下颌关节紊乱病临床疗效分析

Clinical Study of Temporomandibular Disorder with Malocclusion by Orthodontic Treatment.

目的 分析并评价矫治错(牙合)同时治疗颞下颌关节紊乱病(TMD)的临床效果。方法 采用直丝弓技术矫治各种错(牙合)畸形伴TMD患者42例,详细记录治疗前、治疗6个月、治疗结束、治疗结束后2年的牙(牙合)情况及TMD症状、体征变化、颞下颌关节(TMJ)X线片情况。结果 30例患者TMD症状及体征基本痊愈,占71.4％;好转7例,占16.7％;无效或加重5例,占11.9％。结论 错(牙合)畸形伴TMD的年轻患者经正畸矫治可以恢复咬合或作(牙合)重建,建立(牙合)平衡,使颞下颌关节、下颌回复到正常解剖位置。但已经发生器质性损害或TMJ解剖结构不对称的患者,治疗效果有待于进一步观察。

Objective To evaluate predictability and treatment outcome of temporomandibular disorder with malocclusion by orthodontic treatment. Methods 42 subjects with temporomandibular disorder and malocclusion were treated by straightwires appliance. The occlusional models, TMD symptoms, TMJ X-ray were analyzed before and after treatment. Results 30 subjects (73.8 percent) completely recovered from TMD, 7 subjects (16.7 percent) partly recovered, and 5 subjects (11.9 percent) had not clinical changes. Conclusion It is useful to some malocclusion with TMD by orthodontic treatment.
