目的探讨唇颊侧骨密质松解术配合尖牙远移装置快速远中移动尖牙的可行性和可靠性。方法将30例成人患者纳入治疗计划,采用随机分组法将患者分为两组,每组15例患者。试验组采用骨密质松解术辅助尖牙快速远中移动对患者进行矫治,对照组采用常规拔牙方法对患者进行矫治,观察尖牙远中移动到位的时间。结果试验组患者尖牙远中移动到位平均需46 d,而对照组尖则需165 d,试验组明显缩短尖牙远中移动的时间,缩短了疗程。结论唇颊侧骨密质松解术明显缩短了远中移动尖牙的时间,为成人患者拔牙矫治提供了一种快速、可靠的治疗方法。
Objective To investigate the feasibility and reliability of lip and buccal mass lysis combined with distal canine distal fossa movement. Methods Thirty adult patients were included in the treatment plan. Patients were divided into two groups with 15 patients in each group. In the test group, the patients were treated by assisted bone decollarization to assist the canine to move rapidly and quickly. The control group was treated by conventional extraction method and the canine was moved in the distance. Results In the experimental group, the canines were moved for a median time of 46 days, while those of the control group needed 165 days. The test group significantly shortened the time for distal canines to move and shorten the course of treatment. Conclusion Occluganeous buccal mass lysis significantly shortens the time of distal canine movement and provides a rapid and reliable treatment for tooth extraction in adult patients.
