To compare minimally invasive extraction and traditional method in the extraction of impacted mandibular third molar.
One hundred and sixty patients with impacted mandibular third molar were equally divided into two groups. Patients in the experimental group were treated with minimally invasive extraction, using implant machine and luxator, while patients in the control group were treated with traditional methods including use of orthodox chisel. The operation time, intraoperative and postoperative complications including deformation of extraction sockets, dry socket, limitation of mouth opening, pain and swelling, and fear were observed and compared between the two groups. The data were analyzed with SPSS18.0 software package.
The operation time was (17.32±1.01) min in the experimental group, significantly shorter than the control group which was (33.46±1.12）min (P<0.05); significant difference was found in the incidence of root fracture, medium or severe tooth sockets deformation and incidence of psychological fear during operation between the control group and experimental group(P<0.05); the degree of mouth opening after surgery, the incidence of moderate or severe pain after surgery was significantly lower in the experimental than in the control group(P<0.05).
Minimally invasive extraction of mandibular impacted wisdom tooth is better than traditional method, with shorter operation time and less intraoperative and postoperative complications, which should be widely applied in clinic.
比较微创拔牙术与传统方法拔除下颌阻生第三磨牙的效果。
将160例下颌阻生第三磨牙患者平均分为两组。实验组采用微创拔牙术，使用种植机和牙挺，而对照组采用传统方法，包括使用传统凿子。观察并比较两组的手术时间、术中及术后并发症，包括拔牙窝变形、干槽症、张口受限、疼痛和肿胀以及恐惧情况。数据采用SPSS18.0软件包进行分析。
实验组手术时间为（17.32±1.01）分钟，显著短于对照组的（33.46±1.12）分钟（P<0.05）；对照组与实验组在牙根折断发生率、中重度牙槽窝变形发生率及术中心理恐惧发生率方面存在显著差异（P<0.05）；实验组术后张口度、术后中重度疼痛发生率显著低于对照组（P<0.05）。
下颌阻生智齿的微创拔牙术优于传统方法，手术时间短，术中及术后并发症少，应在临床上广泛应用。
