CBCT结合微创技术与传统技术拔除埋伏多生牙的临床比较

Contrastive research of clinical effects of the minimally invasive surgery techniques combined with CBCT examination and traditional technologies on the extraction of embedded supernumerary teeth

目的比较CBCT结合微创技术与传统技术拔除埋伏多生牙的临床效果。方法收集2013年至2016年门诊需要拔除的埋伏多生牙患者28例(共52颗埋伏牙),随机分为微创治疗组(12例,23颗)和传统治疗组(16例,29颗)。采用两种不同方法检查并拔除患牙,记录手术时间、术后疼痛及肿胀度和手术并发症情况。结果微创治疗组手术时间(24.7±7.2)min少于传统治疗组(33.4±8.1)min,微创治疗组术后疼痛和肿胀度也低于传统治疗组,这些差异均有统计学意义(P<0.005);在术后并发症上(邻牙损伤、上颌窦或鼻腔交通、干槽症、张口受限),微创治疗组的发生率都低于传统治疗组。结论 CBCT结合微创技术应用于埋伏多生牙的检查和拔除可以有效缩短手术时间,减少术后疼痛和肿胀,同时也可降低术后并发症的发生。

Objective To evaluate different clinical effects of the minimally invasive surgery techniques combined with CBCT examination and conventional technologies on the extraction of embedded supernumerary teeth. Methods Totally 28 patients with 52 embedded supernumerary teeth were selected from 2013 to 2016 and were randomly divided into the minimally invasive group and the conventional group. Respectively two different methods were used to examine and remove the embedded supernumerary teeth. Information of two groups of patients was recorded,including operative time,postoperative pain,postoperative swelling and postoperative complications. Result The operative time of the minimally invasive group（ 24.7±7.2） min was shorter than that of the conventional group（ 33.4± 8.1） min; the rates of postoperative pain and postoperative swelling were lower than those of the conventional group,the differences being statistically significant（ P〈0.005）. The occurrence rates of postoperative complications（ adjacent teeth damage,leakage of maxillary sinus or nasal cavity,dry socket and limitation of mouth opening） in the minimally invasive group were lower than those in the conventional group. Conclusion Minimally invasive techniques combined with CBCT examination used in the extraction of embedded supernumerary teeth can shorten the operation time,reduce the incidence of postoperative pain and postoperative swelling; meanwhile,it can reduce the occurrence of surgical compliance.
