摘要
目的:探讨咬合垂直距离改变对无牙颌TMD患者治疗前后面部形态影响。方法:对无牙颌TMD垂直距离减低的48例患者恢复垂直距离前后,拍头颅侧位X线片并进行测量。结果:咬合垂直距离改变对无牙颌TMD患者治疗前后面部形态主要发生在面下1/3,YA角,MPA角N-Me距离均增加,并有显著性差异,说明恢复垂直距离后,下颌颏部向下向后顺时针移位,TMD症状缓解。结论:恢复无牙颌咬合垂直距离后,下颌颏部向下向后顺时针移位,TMD症状缓解,面部形态相应改变。
Objective:To observe the effect of the facial contour changes before and after vertical dimension restorations of complete dentures in edentulous TMD patients. Methods:Lateral cephalometric radiographs were exposed on the centric occlusion of all 48 patients, and measured before and after vertical dimension restoration. Results:YA, MPA values, and the distance of N-Me was increased respectively. Conclusion:The TMD symptoms and facial contours can be recovered by the changes of vertical dimension in edentulous patients.
