牙槽骨再生正畸治疗成人中重度牙周炎错畸形远期疗效评价

Long-term effect of augmented corticotomy assisted orthodontic treatment for adult patients with moderate to severe periodontitis

目的 ：评价牙槽骨再生正畸治疗成人中重度牙周炎错畸形的远期疗效。方法 ：成人中重度牙周炎错畸形3例,伴不同程度上或下前牙区牙槽骨吸收,平均年龄31岁。经正颌-正畸联合会诊,制订综合治疗计划。系统性牙周治疗后,行牙槽骨再生正畸治疗结合定期牙周检查与维护,矫治结束后随访2~3 a。结果：3例患者均顺利完成治疗,面型及咬合关系获良好改善,牙槽骨吸收区域骨量增加明显且远期效果稳定,术区正畸牙移动到位且未见医源性牙周并发症。结论：针对成人中重度牙周炎错畸形患者,牙槽骨再生正畸是一种较为理想的技术。

PURPOSE： To investigate the long-term effect of augmented corticotomy assisted orthodontic treatment for adult patients with moderate to severe periodontitis. METHODS： A joint orthodontic and orthognathic consultation was performed on 3 adult patients diagnosed as moderate to severe periodontitis with an average age of 31 years old.Augmented corticotomy assisted orthodontic treatment and combined periodontal therapy were carried out with long-term follow-up of 2-3 years. RESULTS： Augmented corticotomy assisted orthodontic treatment resulted in normal facial appearances and occlusal relationships without the occurrences of periodontal iatrogenic sequelae. The long-term effect of alveolar augmentation were maintained at the surgical sites. CONCLUSIONS： Augmented corticotomy assisted orthodontic treatment is a promising technique for treatment of adult patients with moderate to severe periodontitis.
