摘　　要：目的分析复杂牙患者120例微创拔牙治疗的疗效及预后。方法选取2015年2月至2016年2月来我科室下颌阻生牙(MIT)拔除患者120例为研究对象,随机分为对照组60例采用传统拔牙术,对照组60例采取微创拔牙术。分别记录2组患者的手术时间、术中出血量、断根、牙龈撕裂及牙窝完整率等情况。结果观察组患者在平均手术时间(27±3)min,平均出血量(7.1±2.8)ml,视觉模拟评分(VAS)(8.3±1.4)分等方面明显优于对照组[(32±4)min,(10.1±2.4)ml,(9.9±1.3)分],差异有统计学意义(P<0.01)。在术后,观察组患者的断根率83%,牙龈撕裂率13%及牙窝完整率90%分别优于对照组(55%,40%,70%),差异有统计学意义(P<0.01)。在治疗后,观察组MIT拔除患者出现2例创面感染、2例出血肿胀,1例张口受限,总并发症率为8%,而对照组各类并发症例数明显较多,总并发症率为25%,2组差异有统计学意义(χ2=6.000 0,P=0.014 3)。治疗后,观察组患者给予高度认可率为83%,总认可率为97%,明显优于对照组患者的65%与80%,2组差异有统计学意义(P<0.01)。结论采用微创拔牙术治疗复杂牙患者,术中情况较优,术后并发症率低,认可度高,疗效突出。Objective To analyze the therapeutic efficacy and prognosis of 120 cases of mandibular impacted tooth（MIT） following minimally invasive extraction. Methods One hundred and twenty patients with MIT removal in our department between February 2015 and February 2016 were enrolled in this study. The patients were randomly di-vided into the control group（n=60） to undergo traditional tooth extraction or the study group（n=60） to undergo minimally invasive tooth extraction. The two groups were recorded for operation time, blood loss, root debridement, gingival tear and the completeness of tooth socket. Results The mean operative time [（27±3） min], mean blood loss [（7.1±2.8）ml] and VAS [（8.3±1.4）] in the study group were significantly better than those in the control group [（32±4）min,（10.1±2.4）ml,（9.9±1.3）, P〈0.01], suggesting that minimally invasive tooth extraction may be associated with less pain and trauma. After operation, the rates of root debridement（83%）, gingival tear（13%） and complete tooth socket（90%）in the study group were significantly better than those in the control group（55%,40%,70%）, suggesting the prominent efficacy of minimally invasive tooth extraction. After treatment, there were two cases of wound infection, two of hemor-rhage and swelling, and one of difficulty opening mouth in the study group（total rate of complications： 8%）; in con-trast, there were more cases of these complications in the control group（total rate of complications： 25%）, with signifi-cant difference between the two groups（ χ^2= 6.000 0, P =0.014 3）. After treatment, 50（83%） patients in the study group rated high satisfaction with the outcomes, and the overall rate of satisfaction was 97%, which were significantly better than 65% and 80%, respectively, from the control group（ χ^2=11.009 1, P=0.000 9; χ^2=8.086 35, P=0.004 5）.Conclusion Minimally invasive extraction of MIT may offer better intra-operative process, less postoperative complications,
