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 aug-mentation 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.
