前牙残根正畸牵引加牙冠延长在前牙牙体缺损修复中的应用效果

探讨前牙牙体缺损修复中应用前牙残根正畸牵引加牙冠延长治疗的临床效果。方法 选取 我院2022年3月-2023年3月收治的120例前牙牙体缺损患者为研究对象，随机分为对照组和观察组，各 60例。对照组予以牙冠延长术治疗，观察组予以前牙残根正畸牵引加牙冠延长治疗，比较两组修复效果、 牙周健康情况和并发症发生情况。结果 观察组修复优良率为96.67%，高于对照组的80.00%（P＜0.05）；两 组治疗后的牙周探诊深度、牙龈指数、牙齿松动度均低于治疗前，且观察组低于对照组（P ＜0.05）；观察 组并发症发生率为5.00%，低于对照组的20.00%（P＜0.05）。结论 前牙牙体缺损修复中应用前牙残根正畸 牵引加牙冠延长治疗可改善患者的牙周健康情况，提升修复效果，降低并发症发生风险。

Application Effect of Orthodontic Traction of Anterior Teeth Residual Root and Crown Lengthening in the Repair of Anterior Teeth Defect

To explore the clinical effect of orthodontic traction of anterior teeth residual root and crown lengthening in the repair of anterior teeth defect. Methods A total of 120 patients with anterior tooth defect admitted to our hospital from March 2022 to March 2023 were randomly divided into control group and observation group, with 60 patients in each group. The control group was treated with crown lengthening, and the observation group was treated with orthodontic traction of anterior teeth residual root and crown lengthening. The repair effect, periodontal health and complications were compared between the two groups. Results The excellent and good rate of repair in the observation group was 96.67%, which was higher than 80.00% in the control group (P <0.05). The periodontal probing depth, gingival index and tooth mobility of the two groups after treatment were lower than those before treatment, and the observation group was lower than the control group (P <0.05). The incidence of complications in the observation group was 5.00%, which was lower than 20.00% in the control group (P <0.05). Conclusion In the repair of anterior teeth defect, orthodontic traction of anterior teeth residual root and crown lengthening can improve the periodontal health of patients, improve the repair effect and reduce the risk of complications.
