高速气涡轮切割手机联合专用加长裂钻对拔除下颌阻生第三磨牙的效果分析

目的:探讨牙科高速气涡轮切割手机配合阻生牙专用加长裂钻拔牙对口腔外科门诊需要拔除下颌阻生第三磨牙患者的影响。方法:选取我院收治的59例需要拔除下颌阻生第三磨牙患者,按照随机数字表法将所有患者随机分为试验组和对照组两组。其中试验组患者采用牙科高速气涡轮切割手机辅助阻生牙专用加长裂钻进行拔牙,而对照组患者则采取传统的劈骨分牙法,通过两组患者的术后复诊对患者的下唇麻木、断根等发生率以及张口受限、疼痛、肿胀等情况进行评价。结果:根据我院对两组患者的术中情况及术后并发症情况进行统计分析,结果显示试验组患者的手术时间为(25.68±6.83)min,明显低于对照组患者(35.23±14.23)min,t=3.962,P=0.000]。试验组患者中仅有1例术后出现断根情况,无其他并发症出现;而对照组患者术后则有3例断根情况和1例下唇麻木患者(后逐渐缓解)、1例下颌关节疼痛以及1例舌侧骨板骨折患者。根据我院对两组患者术后1d的临床资料进行统计分析,结果显示试验组患者术后1d面部肿胀程度明显比对照组患者轻(P0.05);试验组患者的疼痛情况明显优于对照组患者(P0.05);试验组患者的张口受限程度明显比对照组患者轻(P0.05)。结论:牙科高速气涡轮切割手机配合阻生牙专用加长裂钻拔牙对口腔外科门诊需要拔除下颌阻生第三磨牙患者具有较好的临床治疗效果,值得在临床上加以广泛推广和运用。

Dental High Speed Gas Turbine Cutting Handpiece with Impacted Teeth Special Extended Fissure Bur for Extraction of Impacted Mandibular Third Molars

ABSTRACT Objective: To investigate the effects of special extended fissure bur assisted by dental high speed air turbine cutting handpiece on the extraction of impacted mandibular third molar in patients. Methods: Selected 59 cases of patients who need extraction of impacted mandibular third molar. According to the random number table method, all patients were randomly divided into two groups, experimental group and control group. The patients in the experimental group had the mandibular third molar extracted by special extended fissure bur assisted with dental high speed air turbine cutting handpiece, while those in control group had traditional chisel method. Evaluate and compare the postoperative incidence of lower lip numbness and root broken, and limitation of mouth opening, pain, swelling, etc. The surgery situation and postoperative complications were analyzed. Results: The results showed that the operation time of the experimental group was (25.68 + 6.83) min, significantly lower than that of the control group patients (35.23+14.23) min, t=3.962, P = 0.000]. There were no complications observed in the experimental group except that one case had the root broken after operation. While in the control group, there were three cases of postoperative root broken, one case of lower lip numbness (gradually eased later), one case of mandibular joint pain and one case of lingual bone plate fracture. According to the clinical data calculated at 1d after operation, the facial swelling degree was significantly lighter in experimental group than in control group (P < 0.05). And the pain of patients in the experimental group was significantly better than in the control group (P<0.05). Patients in the experimental group also had less limitation in mouth opening than those in control group (P<0.05). Conclusion: Dental high speed air turbine cutting handpiece with impacted teeth special extended fissure bur had a better clinical therapeutic effect on extraction of mandibular impacted third molars. It is deserved to be widely popularized and applied in clinic.
