This retrospective study is aimed at (I) assessment of tooth loss and related parameters after jaw curettage of benign lesions and (II) assessment of the outcome of jaw curettage supported by splint insertion after at least six months of follow-up. For (I), patients who had jaw curettage surgery in the Department of Oral and Maxillofacial Surgery, Sun Yat-sen Memorial Hospital, Sun Yat-sen University (Guangzhou, China) from July 2015 to June 2019 were included. For part (II), consecutive patients who came to the department from July to December 2019 that were additionally treated with dental splinting were involved in this study. Based on the patient records, age, gender, initial tooth mobility, follow-up outcome, and potential tooth loss (intra- or postoperatively) were recorded. Based on available radiographs, alveolar crest bone loss and root surface area supported by bone (RSA) were determined.
(I) 128 patients with 305 teeth were included, of which 40 teeth were lost (success rate 86.9%), without statistical difference in gender, age, or tooth type ( > 0.05). Tooth mobility, RSA, and the presence of alveolar crest bone defects were associated to tooth loss ( < 0.001). (II) 17 patients with a medium follow-up period of 11 months (range 9 to 13 months) were enrolled. All lesion-involving teeth supported by splint treatment at risks of loss were preserved, showing an effective tooth retention rate in 17/17 cases (74/74 teeth, success rate: 100%).
Tooth mobility and bone loss (lesion-related and/or periodontal) are potential risk predictors for tooth loss in the first year after jaw curettage surgery. Dental splints could be recommendable for teeth involved by jaw benign lesions with little bone support.
本回顾性研究旨在：（I）评估颌骨良性病变刮除术后的牙齿缺失及相关参数；（II）评估颌骨良性病变刮除术后至少 6 个月采用夹板固定治疗的结果。对于（I），我们纳入了中山大学孙逸仙纪念医院口腔颌面外科 2015 年 7 月至 2019 年 6 月行颌骨刮治术的患者。对于（II），我们纳入了 2019 年 7 月至 12 月就诊于该科室且另外采用牙夹板固定治疗的连续患者。根据患者病历记录了年龄、性别、初始牙齿松动度、随访结果和潜在的牙齿缺失（术中或术后）。根据现有的 X 线片，确定牙槽嵴骨丧失和骨支持的根面面积（RSA）。
（I）共纳入 128 例患者的 305 颗牙，其中 40 颗牙（成功率 86.9%）丢失，性别、年龄或牙位无统计学差异（>0.05）。牙齿松动度、RSA 和牙槽嵴骨缺损的存在与牙齿缺失相关（<0.001）。（II）共纳入 17 例患者，平均随访时间为 11 个月（9 至 13 个月）。所有存在牙体缺失且有发生牙体缺失风险的病变累及牙在夹板治疗后均保留，17/17 例（74/74 颗牙，成功率：100%）有效保留了病变累及牙。
颌骨良性病变刮除术后第 1 年，牙齿松动度和牙槽骨丧失（与病变相关和/或牙周相关）是牙齿缺失的潜在风险预测因素。对于骨支持较少的颌骨良性病变累及牙，可推荐采用牙夹板固定治疗。
