治疗性全口义齿矫正不良颌位的研究

目的　评价一种治疗性全口义齿矫正全口义齿患者不正确颌位关系的效果。方法　让11例有不良颌位的无牙颌患者戴用笔者制作的一种上颌后牙为瓷人工牙,下颌后牙区似导板的治疗性全口义齿。采用下颌运动轨迹描记仪,记录患者戴用治疗性全口义齿矫正前后颌位的改变情况。结果　矫正后闭口轨迹末端位的集中性明显提高;下颌运动轨迹的对称显著改善;CRO-ICO三维滑动幅度减少,滑动中牙齿能均匀稳定的接触。结论　治疗性临时全口义齿,对矫正前伸、偏斜等无牙颌患者具有一定的作用。

Correction of Malmaxillomandibular Relation with Therapeutic Complete Denture

Objective The purpose of this study is to evaluate the effect of therapeutic complete denture in rectifying malmaxillomandibular relation of complete.Methods 11 patients were treated with therapeutic complete denture, of which the maxillary premolars and molars were artificial ceramic teeth and mandibular premolar and molar region was just like a splint. The changes before and after the treatment were recorded by mandibular kinesiograph(MKG). The effect was evaluated by seft_control comparison.Results After rectifying, the concentration of the closing locus end position evidently increased, the symmetry of mandible motion significantly improved, CRO_ICO three_dimensional slide range decreased and moreover, the teeth had even and stable contact during sliding.Conclusion The temporary therapeutic complete denture had a fair effect in rectifying malmaxillomandibular relation of edentulous patients.
