目的:研究分析采用高速涡轮手机拔除下颌阻生第三磨牙的微创术式设计及其临床效果。方法:回顾性分析2009年5月-2012年10月期间,我科收治的430例下颌阻生第三磨牙患者的临床资料,其中普通患者214例,骨埋伏阻生牙患者216例,按照患者治疗期间采用的不同临床治疗措施,将患者分为两组,对照组患者采用传统锤击术拔牙,观察组患者采用高速涡轮手机拔除,分析两组患者治疗期间的张口度、疼痛程度、断根率以及组织肿胀情况等。结果:普通阻生牙患者采用涡轮机治疗和锤击治疗的时间分别为(9.22±2.06)分钟、(10.20±1.44)分钟,(P>0.05);骨埋伏阻生组患者中采用两种治疗方式的时间分别为(19.16±2.83)分钟、(36.10±4.50)分钟,(P<0.05)。不论阻生程度如何,采用涡轮机治疗的疼痛程度明显小于锤击治疗组,且张口受限较小,术后恢复快,断根率低,(P<0.05)。结论:经规范设计采用涡轮手机治疗下颌阻生第三磨牙具有良好的临床效果,值得临床推广。
OBJECTIVE: To study and analyze the minimally invasive surgical design and clinical effect of high-speed turbine mobile extraction of mandibular impacted third molars. Methods: The clinical data of 430 patients with mandibular impacted third molars admitted in our department from May 2009 to October 2012 were retrospectively analyzed. Of them, 214 cases were common and 216 cases were implanted with impacted bone. According to the patients The patients were divided into two groups according to the different clinical treatment measures during the treatment. The patients in the control group were extracted by traditional hammering technique. The patients in observation group were removed by high-speed turbine handpiece. The mouth opening degree, pain degree, As well as tissue swelling and so on. Results: The duration of treatment with turbine and hammering treatment was (9.22 ± 2.06) minutes and (10.20 ± 1.44) minutes, respectively (P> 0.05). There were two kinds of treatment (19.16 ± 2.83) minutes, (36.10 ± 4.50) minutes, respectively (P <0.05). Regardless of the extent of impaction, the degree of pain treated with turbine was significantly less than that of hammer-treated group, with limited mouth opening, rapid recovery after operation, and low root-breaking rate (P <0.05). Conclusion: The standard design of the turbine handpiece impacted mandibular third molar has good clinical results, it is worth clinical promotion.
