目的:探讨滑动直丝弓矫治技术治疗上颌尖牙阻生的临床疗效。方法:选取我院2010年1月-2012年2月收治的上颌尖牙阻生患者42例,将其随机分为对照组和观察组,每组21例。对照组采用传统方法治疗,观察组采用滑动直丝弓矫治技术治疗,比较两组患者临床疗效。结果:观察组手术成功率90.5%,明显优于对照组61.9%,组间差异(P<0.05);观察组并发症发生率9.5%,明显低于对照组28.6,组间差异(P<0.05)。结论:对于上颌尖牙阻生患者,采用滑动直丝弓矫治技术治疗,具有成功率高、并发症少、疗效显著等优点,可有效保留上颌埋伏阻生尖牙,值得临床推广及应用。
Objective: To investigate the clinical effect of sliding straight wire appliance in the treatment of maxillary canine impaction. Methods: Forty-two cases of maxillary canine impacted patients admitted from January 2010 to February 2012 in our hospital were randomly divided into control group and observation group, 21 cases in each group. The control group was treated by traditional method. The observation group was treated by sliding straight wire arch technique. The clinical curative effect was compared between the two groups. Results: The success rate of operation in observation group was 90.5%, which was significantly better than that in control group (61.9%, P <0.05). The complication rate in observation group was 9.5%, which was significantly lower than that in control group (P <0.05) ). Conclusion: For maxillary canine impacted patients, the treatment of sliding straight wire arch has the advantages of high success rate, less complications and significant curative effect, which can effectively preserve the maxillary impacted canines and is worthy of clinical promotion and application.
