Evaluation of the Role of Distal Bone Removal or Increased Gap in the Extraction of Lower Mesial Impacted Wisdom Teeth in Lower Mandibular Position

目的研究分析在下颌低位近中阻生智齿拔除时其远中去骨或增隙的作用。方法将我院于2015年7月—2016年5月诊治的下颌低位近中阻生智齿患者200例视为研究对象,平均分为对照组和观察组,每组各100例。对照组患者采取骨凿劈冠、去骨拔出方式,观察组患者采取先行涡轮牙钻对牙冠切割后剔除远中部分骨质,于颊侧远中增隙将智齿拔出。记录并比较两组患者手术时间、术后肿胀程度。结果观察组患者智齿手术时间、术后肿胀程度均低于对照组(P<0.05)。结论下颌低位近中阻生智齿拔除时,远中去骨或增隙能够起到积极作用,提高临床效果,减少并发症发生。

Objective To analyze the role of the distal bone removal or increased gap in the extraction of the lower mesial impacted mandibular wisdom teeth. Methods 200 cases of lower and middle impacted wisdom teeth in lower mandibular position from July 2015 to May 2016 in our hospital were considered as the subjects, they were divided into the control group and the observation group, 100 cases in each group. The control group was taken with chisel chisel, to pull out the way of bone, the observation group was taken on the part of turbine drill crown after cutting in far removed, would pull out the teeth to the buccal distal increase gap. The time of operation and the degree of postoperative swelling were recorded and compared between the two groups. Results The time of the operation and the degree of swelling after the operation were lower in the observation group than in the control group （P 〈 0.05）. Conclusion When the mandibular lower mesial impacted wisdom teeth are removed, the distal bone or the increase of the gap can play a positive role in improving the clinical efect and reducing the complications.
