摘要: 目的 评估上颌窦解剖因素(窦腔宽度、窦腔角度和窦底形态)对穿牙槽嵴上颌窦底提升骨增量材料改建的影响。方法 纳入23名患者共36个种植位点,分析术后6个月和术后即刻种植体根端骨高度和种植体周围骨密度变化,评估上颌窦解剖因素对上颌窦内骨增量材料改建的影响。结果 窦腔宽度、窦腔角度和窦底形态(突入角度)与种植体根端骨高度变化存在正相关,P<0.01。窦底形态(突入角度)与种植体周围骨密度变化存在负相关,P<0.05。剩余垂直骨高度(residual bone height,RBH)与骨增量材料改建不具有统计学显著性,不同颊腭侧骨壁接触数对骨增量材料改建的影响不具有统计学显著性。结论 上颌窦解剖因素与上颌窦内骨增量材料改建存在相关性,术前应仔细评估上颌窦的解剖形态。

Abstract: Objective To evaluate the effects of anatomical factors (sinus cavity width, sinus cavity angle, and sinus floor morphology) on the reconstruction of bone graft materials for transalveolar technique for sinus floor elevation. Methods A total of 36 implant sites in 23 patients were included to analyze the changes in bone height and bone density at 6 months and immediately after surgery, and to evaluate the effect of anatomical factors of maxillary sinus on bone graft material modification in the maxillary sinus. Results The sinus cavity width, sinus cavity angle, and sinus floor morphology (intruding angle) were significantly positively correlated with bone height changes, P<0.01. Sinus floor morphology (intruding angle) was negatively correlated with changes in bone density around the implant, P<0.05. There was no significant correlation between RBH and bone graft material reconstruction, and different contact numbers of the bone walls had no significant effect on bone graft material reconstruction. Conclusion There was a correlation between the anatomical factors of the maxillary sinus and the reconstruction of bone graft materials in the maxillary sinus, and the anatomical morphology of the maxillary sinus should be carefully evaluated before surgery.
