35例成人中重度牙周炎患者牙槽骨再生正畸的疗效评价

Effectiveness of augmented corticotomy assisted orthodontics in 35 adult patients with moderate to severe periodontitis

目的:定量评估伴下前牙区中重度牙周炎成人错畸形患者的牙槽骨再生正畸疗效。方法:从上海交通大学医学院附属第九人民医院口腔颅颌面科2017年1月起就诊的连续病例中选择下前牙区中重度牙周炎且接受牙槽骨再生正畸治疗的35例成人患者的102颗下切牙作为研究对象。通过牙周专科检查及锥形束CT(cone-beam CT,CBCT)评价不同观察时间点术区的牙周软硬组织状况。采用SAS 9.1软件包对数据进行统计学处理。结果:所有患者治疗结束面型及咬合关系良好,牙周炎症得到控制,术区未见牙根吸收。根尖水平骨增量效果好,1/2与3/4根长水平的唇侧骨厚度及唇、舌侧牙槽骨高度在治疗过程中维持稳定。结论:牙槽骨再生正畸技术治疗伴中重度牙周炎成人错畸形,具有良好的临床应用前景。

PURPOSE:To quantitatively evaluate the effect of augmented corticotomy assisted orthodontics in adult patients with moderate to severe periodontitis.METHODS:The sample comprised 102 mandibular incisors of 35 adult patients with moderate to severe periodontitis in mandibular anterior region who accepted augmented corticotomy assisted orthodontic treatment selected from consecutive patients at the Department of Oral and Craniomaxillofacial Surgery,Shanghai Ninth People's Hospital since Jan.2017.Periodontal soft and hard tissue measurements were appraised with the help of periodontal clinical assessment and cone-beam CT(CBCT)examination at different time points.SAS 9.1 software package was used for data analysis.RESULTS:Facial appearance aesthetics,fine occlusal relationships,and effectively controlled periodontal inflammation were realized for all patients after treatment;moderate to severe,favorable bone augmentation on the labial side at root apex level was achieved with minimal root resorption,bone thickness on the labial side at 1/2 and 3/4 root length level was maintained as well as vertical alveolar bone level on both labial and lingual sides.CONCLUSIONS:Augmented corticotomy assisted orthodontics is a promising approach for the treatment of adult patients with moderate to severe periodontitis.
