下颌有阻生倾向智牙胚与阻生智牙拔除术的比较研究

Extraction of Impacted Mandibular Third Molar Germs and Impacted Mandibular Third Molar:a Comparative Study

目的:比较下颌有阻生倾向的智牙胚拔除术与下颌阻生智牙拔除术的手术难度及术后并发症。方法:研究组选取有阻生倾向的下颌智牙胚拔除术病例41例,并随机收集成年下颌埋伏阻生智牙拔除病例40例作对照。收集两组拔牙手术操作时间、术后疼痛、局部肿胀、张口度改变情况的数据,并进行对比分析。结果:下颌有阻生倾向的智牙胚拔除术操作时间短,术后的肿胀、疼痛及开口改变情况,均较对照组轻。结论:下颌有阻生倾向的智牙胚拔除术,操作简单,术后不良反应较轻,恢复快。

Objective： To compare the difficulty and complications of the extraction of impacted mandibular third molar germs and impacted mandibular third molar. Methods： 41 patients with impacted mandibular third molar germs （Group A） and 40 patients with impacted mandibular third molar （Group B） were randomly selected. Param- eters evaluated included the mean operation time, pain response, local swelling, and mouth opening change after tooth extraction. Results： Compared with Group B, the mean operation time of Group A was shorter. Moreover, pain response, local swelling and opening degree change of Group A were less severe. Conclusion： Extraction of the impacted mandibular third molar germs is simple and yielded less resultant complications.
