目的探讨稳定型咬合板治疗颞下颌关节盘前移位的临床疗效。方法颞下颌关节盘前移位患者42例,均采用稳定型咬合板治疗,观察治疗前及治疗后2、4、6周及3个月患者张口度、关节弹响及视觉模拟评分(visual analogue scale,VAS)和Helkimo指数变化。结果经稳定型咬合板治疗后,患者张口度、VAS评分及Helkimo指数均较治疗前改善(P<0.05);20例合并关节弹响者,治疗后13例弹响完全消失。结论采用稳定型咬合板治疗颞下颌关节盘前移位可明显减轻患者关节区疼痛及弹响,改善张口度。
Objective To investigate the clinical effect of stable occlusal plate in the treatment of temporomandibular joint anterior disc displacement. Methods Forty-two patients with anterior disk displacement of temporomandibular joint were treated with stable bite plates. The mouth opening, joint snapping and visual analogue scores were observed before treatment and at 2, 4, 6 and 3 months after treatment scale, VAS) and Helkimo index changes. Results After treatment with stable bite plates, the mouth opening degree, VAS score and Helkimo index were all improved compared with before treatment (P <0.05). Twenty patients with joint snapping disappeared completely after treatment. Conclusion The treatment of temporomandibular joint anterior disc displacement with stable bite plates can significantly reduce the pain and snapping of the joint area and improve the mouth opening.
