摘要 目的:研究牙周病导致前牙漂移的患者的正畸治疗,分析错合畸形复发的病因和预防。方法:通过前牙漂移的牙周病患者20例,运用正畸方法恢复患者外观和咬合关系,术后半年随访取模,对复发的情况进行研究。结果:正畸治疗可以改善上前牙的唇倾,并且可以协调上下颌骨的矢状关系。22例(71%)出现不同程度切牙散在间隙,间隙出现位置中切牙间(50%),中切牙与侧切牙间(31.8%),尖牙近远中(18.2%)。结论:术后的调合和Hawley保持器并不足以能有效地维持牙周病患者的正畸结果。 Objective To study orthodontics treatment of patients with front teeth excursion induced by periodontal diseases and analyse etiologic factors and prevention of malocclusion recrudescence. Methods Through 20 periodontal disease patients with front teeth excursion,we applied orthodontics treatment to resume patients' appearance and occlusion relationship. We got patients' teeth models in the following half year and studied the state of excursion. Results Orthodontics treatment can mend labial gradient of superior anterior teeth and correlate maxilla--mandible arrowy relationship. 22 patients(71% )got various dispersive incisor teeth diastema. The positions of diastema are between median incisor teeth(50%), between median incisor teeth and lateral incisor teeth (3t. 8 %), mesial distal surface of canine teeth (18.2 %). Conclusions Adjustment after operation and Hawley maintainer can't effectively maintain orthodontics treatment results of patients with periodontal diseases.
