摘要
目的 分析正畸治疗过程中快速移动尖牙术后对牙根吸收和改建的影响.方法 选取我院2013年12月~2015年12月收治的安氏Ⅱ类错成年患者16例作为研究对象,拔除双侧上颌第一前磨牙,牙周膜牵引成骨术快速远中移动尖牙30颗,术前及术后3个月分别拍摄CBCT,测量牙根长度及牙槽骨的改建情况.结果 30颗尖牙在3星期内快速远中移动到位,CBCT显示尖牙快速远中移动术后3个月无明显的牙根吸收,远移尖牙的近中已经逐渐改建为正常的骨组织,密度和正常牙槽骨无差异.结论 在正畸治疗过程中,快速移动尖牙具有一定的高效性以及安全性,可缩短疗程.
Objective To analyze the orthodontic treatment process move quickly after the impactof the canine root resorption and remodeling. Methods In our hospital from December 2013 to December2015 were class II malocclusion adult patients 16 cases as the research object, extracted the bilateral maxillaryfirst premolar periodontal ligament distraction osteogenesis rapid canine distal movement 30, preoperativeand postoperative 3 months were taken CBCT, remodeling of alveolar bone and root length measurement.Results 30 canines in 3 weeks of rapid distalize in place, CBCT shows mobile operation fast far in caninesafter 3 months without obvious root resorption, canine distalization through has been gradually converted intonear normal bone tissue, no difference in density and normal alveolar bone. Conclusion In the course oforthodontic treatment, the rapid movement of canines with a certain effi ciency and security, can shorten thecourse of treatment.
