摘要/Abstract

摘要： 摘要：目的：探讨PASS生理支抗矫治技术治疗低位尖牙伴重度拥挤错牙合的特点.方法选取上颌尖牙低位造成的牙列重度拥挤的患者２0例, 其中男性８例，女性１２例，年龄１１－2０岁，平均１4.5岁。拔除4颗第一双尖牙后使用PASS矫治器进行治疗,矫治前后拍摄头颅定位侧位片，对矫治前后头影测量结果进行比较。结果：２0例患者平均治疗时间为16.4±5.1月，矫治结束后上下前牙中线一致，覆牙合覆盖正常，尖窝关系良好。上颌第一磨牙失状向前移1.56±1.1mm，与矫治前相比，无统计学意义(p>0.05)。结论PASS矫治器能够高效矫治低位尖牙造成的重度牙列拥挤。

Abstract: [Abstract] Objective ：To observe the clinical effects of Physiologic Anchorage Control technique in the treatment of maxillary lip-opposite low canine and severely crowding . Methods: 20 patients with maxillary lip-opposite low canine and severely crowed teeth were included, their average years were 14.5. They were extracted 4 first premolars and treated with PASS appliance .Analysis was carried out before and after treatment．Results: After treatment，normal overbite ,overjet and good occlusal relationship were achieved. The upper first molar showed mesial displacement of 1.56±1.1mm, no significant change was found after treatment． Conclusions ：Physiclogic Anchorage Control technique could be effectively and conveniently used in the treatment of patients with severely crowed malocclusion
