上颌窦底骨分隔对内提升术后成骨效果的影响

目的　上颌窦骨分隔被认为是上颌窦内提术的相对禁忌症，文中旨在探讨上颌窦底骨分隔对内提升术后成骨效果的影响。 方法　收集上颌窦底骨分隔需内提升进行种植的患者7例（有分隔组），另随机选取上颌窦无分隔需进行内提升的患者8例（无分隔组），共15例，利用CBCT(Cone Beam Computed Tomography)和Simplant软件对植体周围骨高度及骨密度进行测量，采用SPSS19.0软件对数据进行统计分析。 结果　有分隔组及无分隔组的提升高度，植体根尖高度差，颊侧高度差，根尖区骨密度，颊侧骨密度的对比，P值均大于0.05，两组结果差异无统计学意义。 结论　上颌窦底骨分隔内提升术后的成骨效果无明显影响。

The effect of maxillary sinus septa on osteogenesis after localized management of sinus floor

Objective　To investigate the effect of maxillary sinus septa on osteogenesis after maxillary sinus floor separation.　Methods　7 cases who got maxillary sinus floor separation with maxillary sinus septa (septum group), another 8 cases who got maxillary sinus floor separation without maxillary sinus septa were collected (non-septum group), total 15 cases. The bone height and density were measured by Cone Beam Computed Tomography(CBCT) and Simplant, and the data was statistically analyzed by SPSS19.0. Results　There was no significant difference between the two groups in the lifting height, the height difference between the apical and root, the height difference of the buccal side, the ratio of the bone density of the apical area to the bone density of the buccal bone（P>0.05）.　Conclusions　The maxillary sinus septa has no significant effect on the osteogenesis after localized management of sinus floor.
