上颌埋伏阻生第三磨牙78例微创拔除的临床总结

目的评价微创拔除较为困难上颌埋伏阻生第三磨牙的临床效果。 方法2012年1月至2017年3月期间就诊广州市海珠区口腔医院口腔颌面外科诊断为上颌埋伏阻生第三磨牙共计78例，排除拔牙禁忌证，锥形束CT（CBCT）检查评估患牙位置与毗邻重要解剖结构的位置关系，利用微创拔牙器械与方法拔除患牙。术后1周评估微创拔牙方法的效果以及其并发症发生率等。 结果78例微创拔牙手术时间为3~ 45 min，平均13 min。手术期间患者感觉无明显不适，微创拔牙术后不良反应较低，78例均未出现严重并发症的情况。 结论微创拔牙在拔除较为困难的上颌埋伏阻生第三磨牙中具有一定优势，值得临床推广使用。

Clinical summary on minimally invasive extraction of 78 maxillary impacted third molars

ObjectiveTo evaluate the clinical effect of minimally invasive extraction of difficult maxillary impacted third molars. MethodsSeventy-eight maxillary impacted third molars were involved in this study from January 2012 to March 2017 from the Department of Oral and Maxillofacial Surgery, Stomatology Hospital of Haizhu district. Cone beam CT was executed to find out the location between impacted third molars and adjacent anatomical structures. Excluding extraction contraindications, impacted third molars were extracted using minimally invasive apparatus. Evaluation of effect and complication incidences were made in 1 week after operation. ResultsOperation time lasted from 3 minutes to 45 minutes, with an average of 13 minutes. Patients maintained good comfort and less postoperative discomfort in minimally invasive extraction. None had serious complications. ConclusionIt was practicable and preponderant to adopt minimally invasive extraction for difficult maxillary impacted third molars.
