正畸与导萌手术协同矫治上颌埋伏阻生前牙的临床应用

Effect of orthodontic uprighting and edgewise technique on impacted anterior maxillary teeth

目的:探讨利用方丝弓矫治技术与导萌术协同矫治上颌前牙埋伏阻生的临床疗效。方法:选取我科2009年12月～2010年12月收治的54例上颌前牙埋伏阻生病例应用方丝弓矫治技术结合导萌手术进行矫治为治疗组。设立同期收治的54例上颌埋伏阻生前牙患者,应用活动矫治器治疗为对照组。两组患者一般情况差异无统计学意义(P>0.05),具有可比性。结果:治疗组患者均达到矫治的目标,即前牙覆合覆盖Ⅰ度,后牙尖窝交错,上下牙弓无拥挤及间隙,牙槽排列整齐,被牵引牙齿无松动,牙根无吸收,牙周健康,随访两年,疗效稳定。治疗组治疗时间明显短于对照组,差异有统计学意义,P<0.05。结论:应用方丝弓矫治技术与导萌手术可快速有效地矫治上颌前牙埋伏阻生病例。

Objective. To explore the effect of orthodontic impacted anterior maxillary teeth. Methods： A total of 57 cases with impacted anterior maxillary teeth, who were admitted from Dec 2009 to Dec 2010 were selected as treatment group edgewise technique and orthodontic uprighting, Another 54 cases with impacted a served as control group, and were treated with removable appliance. General clini were similar, without significant difference （P〈0.05）. Results. All patients were group. The degree of anterior overjet was Ⅰ°. The cuspis and crypt of anterior teeth were interlaced with each other. The upper and lower dental arch were not crowded nor of interspace. Dental alveoli were lined up in order. The tracted teeth were not loosened, and showed healthy periodontal tissues, and stable efficacy. treatment group （P〈0.05）. Conclusions： Orthodontic impacted anterior maxillary teeth.
