摘要 目的设计研制双排沟托槽固定矫正装置,并应用模拟(牙合)架进行力学性能测试,分析该矫治系统对正畸牙移动的调控能力.方法①设计并制造双排沟托槽及颊管.托槽设置龈端与切端双排槽沟,规格为0.022×0.028英寸(0.56mm×0.71mm),相距0.8mm.配置相应的双排颊管;②用经典(牙合)架模拟方法进行牙齿反扭转、竖直、整体远中牵引等正畸牙移动形式,与标准方丝弓矫治方法相比较,定量评价双排沟托槽的牙齿移动及调控效率;③应用经典力学原理,结合(牙合)架模拟数据,分析双排沟托槽装置提高正畸牙移动及调控效率的机制.结果(1)成功设计出双排沟矫正装置的三维模拟图形并制造出实际产品;(2)在(牙合)架模拟状况下,双排沟托槽矫正装置对尖牙的反扭转及竖直移动效率均高于对照组(P＜0.01);对尖牙远中牵引的整体移动效率高于对照组(P＜0.01).结论双排弓丝与双排沟托槽翼突底部四点接触所形成的受力平面可能是导致双排沟托槽有效调控正畸牙各种移动的主要机制.
