近中颌面磨除法拔除近中及水平阻生第三磨牙临床安全性分析

Clinical safety analysis of mesio-occlusalf surface grinding method in the removing of mesio and horizontal implied third molar

目的:探讨近中颌面磨除法拔除近中及水平阻生第三磨牙的临床疗效。方法:2018年5月-2020年11月收治近中及水平阻生第三磨牙患者100例,随机分为两组,各50例。对照组采用断冠法治疗;观察组采用近中颌面磨除法治疗。比较两组临床疗效。结果:观察组拔牙时间及出血量均低于对照组,差异有统计学意义(P<0.05);观察组拔牙窝损伤程度、张口受限程度及颞下颌关节不适程度均低于对照组,差异有统计学意义(P<0.05)。结论:近中颌面磨除法拔除近中及水平阻生第三磨牙,安全有效。

Objective:To investigate the clinical effect of mesio-occlusalf surface grinding method in the removing of mesio and horizontal implied third molar.Methods:From May 2018 to November 2020,100 cases of mesio and horizontal implied third molars patients were enrolled,they were randomly divided into two groups with 50 cases in each group.The control group was treated by crown breaking method.The observation group was treated by mesio-occlusalf surface grinding method.The therapeutic effects between the two groups was compared.Results:The tooth extraction time and bleeding volume in the observation group were lower than those in the control group,the differences were statistically significant(P<0.05).The severity of tooth extraction socket injury,mouth opening restriction,and mandibular joint discomfort in the observation group were significantly lower than those in the control group,the differences were statistically significant(P<0.05).Conclusion:It is safe and effective to remove the implied third molar by mesio-occlusalf surface grinding method.
