One of the main reasons for orthodontics and orthognathic surgery is the prevention of dental loss caused by periodontal disease. Until now there have been no published data describing the periodontal situation near interdental osteotomies after orthognatic surgery. The purpose of this study was to evaluate this situation.
Thirty patients with Class II malocclusions were studied 4 to 10 years after segmental orthognathic surgery, analyzing the periodontal condition near osteotomies with the aid of periapical and panoramic radiographs.
Fifty-one pathologic periodontal lesions were found in the 74 segmental osteotomy sites. There were 35 segmental areas with osseous periodontal defects and 16 segmental areas with missing teeth.
A high incidence of dental and periodontal trauma occurs in the region of segmental osteotomies after orthognathic surgery.
正畸和正颌外科的主要原因之一是预防牙周病导致的牙齿缺失。到目前为止，尚无已发表的数据描述正颌外科手术后牙间截骨术附近的牙周情况。本研究的目的是评估这种情况。
对30例II类错牙合患者在节段性正颌外科手术后4至10年进行研究，借助根尖片和全景片分析截骨术附近的牙周状况。
在74个节段性截骨部位发现51处病理性牙周病变。有35个节段区域存在骨性牙周缺损，16个节段区域存在牙齿缺失。
正颌外科手术后节段性截骨术区域发生牙齿和牙周创伤的发生率较高。
