成人拔牙正畸矫治中骨密质松解术与尖牙快速移动对加速远中移动尖牙的效果分析

观察成人拔牙正畸矫治中应用骨密质松解术与尖牙快速移动装置的效果分析。方法 选取2015年9月～2017年7月本院收治错畸形患者64为研究对象，按照随机数字表法分为对照组和研究组各32例，对照组采用常规拔牙正畸矫治，研究组在拔牙正畸中采用骨密质松解术与尖牙快速移动装置进行矫治。观察两组尖牙远移到位时间、牙周情况、尖牙牙根吸收情况，比较两组并发症情况。结果 研究组尖牙远移到位时间显著短于对照组；治疗后3个月，两组牙龈指数（GI）、龈沟出血指数（SBI）和菌斑指数（PLI）均显著升高（P＜0.05），研究组与对照组比较差异无统计学意义（P＞0.05）；尖牙远移到位后，研究组尖牙牙根吸收体积显著小于对照组（P＜0.05）；两组并发症发生率比较差异无统计学意义（P＞0.05）。结论 成人拔牙矫治中应用骨密质松解术与尖牙快速移动装置能加速尖牙的远中移动，且安全性较好。

Effect Analysis of Compact Bone Substance Lysis and Rapid Movement of the Canine Teeth in the Orthodontic Treatment by Exelcymosis of Adults

Objective To observe the effect of applying osteolysis release and canine rapid movement device in orthodontic treatment of adult extraction. Methods 64 patients with malocclusion treated in our hospital from September 2015 to July 2017 were selected as the subjects. According to the random number table, they were divided into the control group and the study group, 32 cases in each group. The control group was treated with routine orthodontic treatment by exelcymosis, while the study group was treated with orthodontics and canine rapid movement device during orthodontic tooth extraction. The in-place time of the distal movement of the canine teeth, periodontal condition, and root resorption of the canine teeth were observed, and the complications of the two groups were compared. Results In the study group, the in-place time of the distal movement of the canine teeth was significantly shorter than that in the control group. 3 months after treatment, the gingival index (GI), sulcular bleeding index (SBI) and plaque index (PLI) all significantly increased in the two groups (P < 0.05), and there was no significant difference between the study group and the control group (P > 0.05). After the canine teeth were in place, the root resorption volume of the canine teeth in the study group was significantly smaller than that in the control group (P < 0.05); there was no significant difference in the incidence rate of complications between the two groups (P > 0.05). Conclusion In the orthodontic treatment by exelcymosis of adults, the application of osteolysis release and canine rapid movement device in adult tooth extraction can accelerate distal movement of the cuspid and has better safety.
