目的:比较45°仰角冲击式气动手机拔牙法和传统骨凿拔牙法拔除下颌低位阻生智齿的不同临床疗效。方法:将240颗下颌低位阻生智齿随机分为研究组与对照组,分别采用冲击式气动手机拔牙法(研究组)和传统骨凿去骨拔牙法(对照组)拔除。比较两组拔除的手术时间,评价两组术中、术后并发症的发生情况,并进行统计学分析。结果:研究组手术时间比对照组手术时间短(P<0.05)。两组患者术后并发症的发生差异均有统计学意义(P<0.05)。结论:采用45°仰角冲击式气动手机拔牙法拔除下颌低位阻生智齿的临床效果要优于传统骨凿拔牙法,值得临床推荐。
OBJECTIVE: To compare the different clinical effects of 45 ° elevation impact pneumatic handpiece extraction and conventional osteotomy extraction on low mandibular impacted wisdom teeth. Methods: A total of 240 mandibular lower occlusion wisdom teeth were randomly divided into study group and control group, and were implanted with impact pneumatic handpiece extraction (study group) and traditional bone chisel extraction and extraction (control group) respectively. The operation time of the two groups were compared, the incidence of intraoperative and postoperative complications were evaluated, and statistical analysis was performed. Results: The operation time of the study group was shorter than that of the control group (P <0.05). There were significant differences in postoperative complications between the two groups (P <0.05). Conclusion: The 45 ° elevation impact pneumatic handpiece removal of lower jaw impacted wisdom teeth clinical effect is superior to the traditional osteotomy extraction method, it is clinically recommended.
