运用Damon自锁托槽不拔牙矫治女性牙列拥挤患者的疗效及唇型变化的研究
朱彬 周奇 占江鄂 杨再波[摘要]目的:探究运用Damon自锁托槽不拔牙矫治女性牙列拥挤患者的疗效及唇型变化。方法:选取2015年12月-2019年12月笔者医院口腔诊疗中心收治的120例不拔牙矫正女性患者为研究对象,采用随机数字表法分为观察组(62例)和对照组(58例),对照组采用传统托槽不拔牙矫治,观察组采用Damon自锁矫治。观察矫治6个月后两组头颅侧位片、模型及牙弓变化及拆除托槽后唇部软组织变化情况。结果:治疗后,观察组上下颌尖牙、第一前磨牙、第二前磨牙及磨牙宽度、上下牙弓周長均大于治疗前,差异有统计学意义(P<0.05);治疗后,对照组上颌尖牙、上下颌第一前磨牙及上下颌第二前磨牙宽度、上下牙弓周长均大于治疗前,差异有统计学意义(P<0.05),而上下颌磨牙宽度、下颌尖牙宽度与治疗前比较,差异无统计学意义(P>0.05);治疗后,观察组与对照组上下颌尖牙、上下颌第一前磨牙、上下颌第二前磨牙及上下颌磨牙宽度,上下牙弓周长比较差异无统计意义(P>0.05)。拆除托槽后,观察组LL'-X小于治疗前(P<0.05),即治疗后LL'-X少于治疗前约1.35 mm。结论:Damon自锁矫治对不拔牙矫正女性患者有扩弓作用,一定程度上可改变下唇软组织。
