微创拔牙法拔除下颌近中阻生牙生理微创的观察

Survey on the physiological minimally invasive effect of minimally invasive surgery in the removal of impacted mesial mandibular molars

目的研究微创拔牙法拔除下颌近中阻生牙生的生理微创效果。方法选择2016年3月～2018年1月来我院拔除下颌近中阻生牙的324例患者作为研究对象,按照随机数字表法分为研究组与对照组,每组各162例,研究组采取微创拔牙法,对照组采取常规拔牙,比较两组临床效果。结果经过观察两组患者治疗效果看出,研究组优良率94.44%较对照组81.48%提高(P <0.05);研究组并发症发生率15.43%比对照组56.17%低,结果具有统计学意义(P <0.05)。结论微创拔牙法在下颌近中阻生牙拔除中具有重要意义,进一步增强生理微创效果,减少并发症发病率,安全性较高,为预后提供保障。

Objective To observe the physiological minimally invasive effect of minimally invasive surgery in the removal of impacted mesial mandibular molars. Methods Three hundred and twenty-four patients underwent the removal of impacted mesial mandibular molars who treated from March 2016 to January 2018 in our hospital were selected as research object. The subjects were randomly divided into study group and control group, 162 cases in each group. The study group received the minimally invasive surgery, the control group received the conventional tooth extraction. The clinical effect of the two groups were compared. Results The good rate in the study group（94.44%） was significanlly higher than that in control group（81.48%）, the difference was statistically significant（P 〈 0.05）; The incidence rate of complications in the study group（15.43%） was significanlly lower than that of control group（56.17%）, the difference was statistically signifieant（P 〈 0.05）. Conclusion The minimally invasive surgery in the removal of impacted mesial mandibular molars is of great importance, which can increase the physiological minimally invasive effect, reduce the incidence rate of complications and improve the clinical safety and prognosis.
