伴慢性上颌窦炎上颌窦底提升的临床研究

Clinical research of the osteotome sinus floor elevation in patients with chronic maxillary sinusitis

目的分析伴有慢性上颌窦炎的患者行冲压法上颌窦底提升后种植体周围的骨改建情况。方法回顾性选择2015年1月至2016年6月在本院就诊的患者60例,根据黏骨膜厚度分为炎症组和对照组,在术后不同时期观察骨量的变化。结果通过独立t检验,术后6个月、3年时分别对两组病历的种植体根尖骨高度、边缘骨吸收进行对比,差异均无统计学意义(P>0.05)。在术后3年时,炎症组的垂直骨增量明显低于对照组,差异具有统计学意义(P<0.05)。结论伴有慢性上颌窦炎的患者行冲压法上颌窦底提升安全可靠,患者预后良好。

Objective To analyze the bone remodeling around the implant in patients with chronic maxillary sinusitis after the osteotome sinus floor elevation(OSFE).Methods 60 patients with implant restoration in the posterior maxilla area by OSFE from January,2015 to June,2016 in our department were selected retrospectively in this study.They were divided into two groups according to the mucosal thickness.Changes in marginal bone level over time were observed.Results By the Independent sample t test,the apical bone height(ABH)and marginal bone loss(MBL)was compared between the two groups at 6 months and 3 years after surgery.There was no statistically significant difference in ABH and MBL between the two groups(P>0.05).3 years after surgery,the VBG in the inflammation group was significantly lower than that of the control group,and the difference was statistically significant(P<0.05).Conclusion For patients with chronic maxillary sinusitis,it is feasible to use the Osteotome sinus floor elevation,and the prognosis is good.
