【摘要】：目的 :研究微种植体支抗结合改良骨皮质切开术压低内收上前牙的效果。方法 :实验组18例,对照组22例,实验组采用微种植体结合骨皮质切开压低内收上前牙,对照组单纯使用种植体压低内收压低前牙。分别于矫正开始和结束时拍摄CBCT并测量SNA角、上前牙暴露程度(UICE)、上前牙切端到上腭平面(UIPP)距离和角度、鼻唇角、牙根吸收量,计算两组从开始内收压低到内收压低结束的平均时间。单因素方差分析两组间差异。结果:实验组SNA角、UICE、UIPP距离和角度、鼻唇角变化值和牙根吸收量均显著优于对照组,压低内收平均时间亦显著低于对照组。结论:采用微种植体支抗结合骨皮质切开术压低内收上前牙可以获得更好的矫正效果,减少牙根吸收,并显著缩短治疗时间。
[Abstract]:Objective: to study the effect of microImplant Anchorage combined with modified cortical osteotomy on the reduction of adductive anterior teeth. Methods: there were 18 cases in the experimental group and 22 cases in the control group. The experimental group was treated with microimplantation combined with cortical incision to reduce the adductive anterior teeth, while the control group was treated with low adductive anterior teeth. CBCT was taken at the beginning and end of correction and SNA angle was measured, the distance and angle from upper anterior tooth incision to upper palatal plane (UIPP), nasal lip angle and root resorption were measured at the beginning and end of correction, respectively. The average time from the beginning of adductive depression to the end of adductive depression was calculated. The difference between the two groups was analyzed by single factor variance analysis. Results: the changes of SNA angle, UICE,UIPP distance and angle, nasal lip angle and root resorption in the experimental group were significantly better than those in the control group, and the average time of depressed adduction was also significantly lower than that in the control group. Conclusion: microImplant Anchorage combined with cortical incision can achieve better correction effect, reduce root resorption and significantly shorten the treatment time of adductive anterior teeth.
