摘　　要：目的·评价正畸压入联合牙周再生性手术治疗上切牙病理性移位(pathologic tooth migration,PTM)的有效性。方法·选取9例发生上切牙PTM的慢性牙周炎患者,在牙周基础治疗后,对11颗患牙邻面的垂直骨缺损进行牙周再生性手术,术后3个月进行正畸压入。分析比较基线(T_0)和正畸治疗结束后(T_1)各项牙周临床参数变化和骨缺损情况。结果·所有患者在治疗结束后牙周临床参数和骨缺损均获得明显改善。平均牙周袋探诊深度减少2.81 mm,平均附着获得为3.38 mm,平均牙龈退缩减少0.56 mm,根方角化龈宽度没有减少。X线片上测量所得邻面骨缺损深度平均减少2.20 mm,骨缺损宽度平均减少0.55 mm。结论·正畸压入联合牙周再生性手术能够有效治疗存在严重骨下袋缺损的PTM患牙,治疗后能够获得良好的牙周软硬组织再生。Objective To evaluate the effectiveness of orthodontic intrusion combined with periodontal regenerative surgery in the treatment of pathologic migration of upper incisors. Methods Nine patients with chronic periodontitis who had pathologic migration of upper incisors were selected. After periodontal initial therapy, periodontal regenerative surgery was performed on the vertical defect around 11 displaced teeth, and then orthodontic intrusion was performed 3 months after the surgery. The differences between baseline（T0） and end of orthodontic treatment（T1） of the periodontal clinical parameters and bone defects were analyzed. Results For all patients, the periodontal clinical parameters and bone defects were significantly improved. The average pocket probing depth reduction was 2.81 mm, the average attachment gain was 3.38 mm, the average gingival recession was reduced by 0.56 mm, and the width of keratinized gingival tissue was not decreased. As measured on the X-ray, the depth and width of the vertical bone defect were reduced by an average of 2.20 mm and 0.55 mm, respectively. Conclusion Orthodontic intrusion combined with periodontal regenerative surgery can effectively treat pathologic migration of the upper incisors with vertical bone defects, and obtain good periodontal soft and hard tissue regeneration.
