文摘目的 :探讨上颌窦底内提升后植骨与不植骨术后6个月上颌窦成骨效果及种植体稳定性的差异。方法 :选择2019年12月—2021年12月于丽水市人民医院行上颌窦底内提升及同期种植的患者150例,按植骨与否分为A组(上颌窦底内提升+植骨)与B组(上颌窦底内提升+不植骨),测量分析患者术前、术后CBCT资料及种植体稳定性,比较2组患者临床疗效是否存在差异。采用SPSS 25.0软件包对数据进行统计学分析。结果:共植入199颗种植体。术后1年,A组种植体存留率为97.6%,B组为95.7%,2组之间无显著差异(P>0.05)。术前剩余牙槽骨高度(residual bone height,RBH)及灰度值(HU)在A组与B组之间无显著差异(P>0.05),术后6个月上颌窦内成骨高度(sinus bone gain,SBG)及HU在2组之间无显著差异(P>0.05)。术后即刻及术后6个月的ISQ值2组之间无显著差异(P>0.05)。结论:在RBH为3~8 mm且计划提升高度为3~4 mm的病例中,植骨与否在上颌窦底内提升术同期种植患者中对种植体的存留率及稳定性影响不大。
