涡轮机联合微创拔牙器械在拔除低位阻生智齿中的临床应用

Clinical application of turbine combined with minimally invasive apparatus on the extraction of lower impacted wisdom teeth

目的比较涡轮机联合微创拔牙器械法与传统拔牙法在下颌低位阻生智齿拔除术中的临床应用,比较分析其优缺点。方法选择需要拔除的下颌低位阻生智齿82例,按照随机分配原则分为实验组与对照组,每组41例。实验组为微创拔牙器械结合高速涡轮牙钻拔牙法,对照组为传统拔牙器械拔牙法。比较两组的断根率、拔牙窝不完整率、牙科畏惧症发生率、手术时间以及术后张口受限度方面的差异。结果实验组均为一期愈合,而对照组有4例因感染致延期愈合;实验组的断根率为7.3%,而对照组为22%;实验组拔牙窝不完整0例,对照组拔牙窝不完整18例;实验组的牙科畏惧症发生2例,对照组发生5例。与对照组相比,实验组的手术时间明显缩短,术后张口受限度更轻,差异具有统计学意义(P<0.05)。结论与传统拔牙法相比,涡轮机联合微创拔牙器械法在下颌低位阻生智齿拔除术中可达到无痛、安全以及微创的目的,具有较好的临床应用前景。

Objective To compare the clinical application of extraction of mandibular impacted wisdom teeth under turbine combined minimally invasive extraction instrument method and traditional method of tooth extraction. The advantages and disadvantages were compared. Methods Eighty-two cases with low mandibular impacted wisdom teeth were selected. They were randomly divided into experimental and control group, with 41 cases in each group. Experimental group was performed with minimally invasive tooth extraction knife tooth extraction in combining with the high speed turbine dental drill tooth extraction. Control group was performed with traditional tooth extraction equipment. Increased rate, rate of incomplete tooth extraction sockets, dental fear of disease incidence rate, operation time and postoperative mouth by the limit of differences were compared. Results The experimental group was healed in primary, whereas the control group had 4 cases with delayed healing caused by infection. The rate of root fracture in experimental group was 7.3~ while the control group was 22%. None of experimental group had incompleted of tooth extraction socket, while the control group had 18 cases with incomplete tooth extraction socket. Two cases in experimental group had dental fear of disease, while 5 cases in the control group. Compared with control group, operation time decreased significantly and postoperative mouth was lighter in experimental group （P〈0.05）. Conclusion Compared to traditional method of tooth extraction, the minimally invasive tooth extraction technology in the mandibular impacted wisdom teeth low urethral surgery are painless, safe and minimally invasive. It has a good clinical application prospects.
