目的:比较“T”形截断法与单纯锤凿劈冠法拔除下颌中位近中水平阻生智牙的疗效。方法:138例需要拔除单侧下颌中位近中水平阻生智牙的患者,随机分为A、B2组,A组70例,B组68例。A组采用“T”形截断法,B组采用传统锤凿冠劈法,去除阻力后拔除。对拔牙术中、术后并发症进行观察,采用SPSS13.0软件包对数据进行统计学分析。结果:A组术中、术后并发症显著少于B组(P<0.05)。结论:“T”形截断法在下颌中位近中水平阻生智牙拔除术中创伤小、并发症少,值得临床推广。
Objective: To compare the curative effect of “T” truncation method and simple hammer chisel splitting method in removing mandibular mid-level impacted wisdom tooth. Methods: One hundred and thirty-eight patients with unilateral mandibular mid-level impaired wisdom teeth were randomly divided into A and B2 groups, 70 cases in group A and 68 cases in group B. A group using “T ” shape truncation method, B group using the traditional hammer chisel crown split method, remove the resistance after removal. The extraction of teeth surgery, postoperative complications were observed using SPSS13.0 software package for statistical analysis. Results: The intraoperative and postoperative complications in group A were significantly less than those in group B (P <0.05). Conclusion: The T-shaped truncation method has less trauma and less complications in mandibular mid-level impacted wisdom tooth extraction, which is worthy of clinical promotion.
