目的：探讨连续分冠在下颌水平阻生智齿拔除术中的临床应用效果。方法选择双侧基本对称、临床均需要拔除的下颌Ⅱ类、中低位、水平阻生智齿患者30例。同一患者双侧分别随机采取连续分冠法或传统一次性分冠法拔除阻生智齿，记录手术时间及术后患者张口度、肿胀度、疼痛、拔牙窝完整性，比较2组手术效果。结果连续分冠组患者的平均手术时间与一次性分冠组无明显差别(P>0．05)，但变异系数明显小于一次性分冠组(P<0．05)，手术效果明显优于一次性分冠组，二者的差异具有统计学意义(P<0．05)。结论连续分冠法拔除下颌水平阻生智齿可以减少术后反应，具有临床使用价值。

Objective To investigate the clinical application of continual crown division in extraction of horizontal impacted mandibular wisdom tooth. Methods Thirty patients with symmetrically horizontal, Class II, low impacted third molars of both sides were included in this study. The wisdom tooth was extracted by continual crown division in one side and by traditional once crown division in the other side. The operation time and postoperative complications were recorded and the effect was statistically evaluated. Results The extraction time was not significantly different between the two methods ( P >0. 05 ) . The operation effect was better in continual crown division group than in traditional once crown division group (P<0. 05). Conclusion Continual crown division could reduce the postoperative reaction in extraction of mandibular horizontal impacted wisdom teeth.
