咬合板矫正下颌偏位的临床研究

目的:探讨咬合板在矫正下颌偏位与颞下颌关节紊乱病及全身姿势的作用。方法:记录、分析、比较伴有下颌偏位的健康有牙颌者及颞下颌关节紊乱病者在戴用矫正颌位的咬合板前后,其正、侧面照片中头部、肩部、腰部的姿势变化。结果:下颌偏位的健康有牙颌者中,在颌位矫正前后头部、肩部、腰部姿势变化者约有50%;在侧面照片中矫正前后表现有80%的被测试者都有头部或脊柱弯曲的姿势变化。矫正颞下颌关节紊乱病者的下颌偏位,可使其临床症状得以改善。结论:下颌偏位与姿势异常及颞下颌关节紊乱病者的全身伴随症状有一定的关联。

Clinical Study of Occlusal Splint in the Treatment of Mandibular Deviation

Objective: To investigate the effect on human body posture in the treatment of mandibular deviation with occlusal splint.Methods: Thirty normal adults or patients with temporomandibular disorders concomitance with mandibular derivation were chosen randomly.The lateral and frontal cephalograms were taken and the changes of postures of head,shoulder and vertebra were recorded before and after treatment of occlusal splint.Results: In frontal cephalograms,50% of subjects were found the changes of postures of head,shoulder and waist after treatment.In lateral cephalograms,postures of the head and vertebra changed in 80% of subjects.After treatment of occlusal splint,the symptoms of patients with temporomandibular disorders were released.Conclusion: Mandibular deviation possibly influenced postures of head,neck and vertebra.Patients with mandibular deviation should be treated as early as possible.
