冠部改良法减少阻生齿拔除术后并发症的临床疗效

Clinical Efficacy of Crown Improvement Method to Reduce the Complications after Impacted Tooth Extraction

目的:比较冠部改良拔牙法和常规的微创法拔除下颌水平阻生智齿的不同临床疗效。方法:将120颗下颌水平阻生智齿随机分为研究组与对照组,研究组采用改良拔牙法,对照组常规微创拔牙法拔除。比较两组拔除的手术时间,评价两组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长,但无明显统计学意义(P>0.05);两组患者术后并发症的发生差异有统计学意义(P<0.05)。结论:采用冠部改良拔牙法拔除下颌水平阻生智齿的疗效要优于常规的微创拔牙法,更能减少术后并发症,值得临床推广。

Objective To compare the clinical efficacy of crown improvement method to reduce the complications after impacted tooth extraction.Methods120impacted mandibular third molars were randomly and equally divided into two groups.Teeth in test group were extracted using the improved tooth extraction method and using the conventional minimally invasive method in control group.All statistical analysis were carried out with SPSS19.0for Windows.Results There was no differences between two groups in extraction time length(P>0.05),but there was significant differences between them in complications(P<0.05).Conclusion Clinical efficacy of crown improvement method in impacted wisdom teeth is better than the conventional minimally invasive extraction method,can reduce postoperative complications,we thought the method was recommendable.
