The aim of this study was to retrospectively determine the effects of applying different treatment methods to the bony access window on the healing outcomes in lateral sinus floor elevation (SFE). Lateral SFE with implant placement was performed in 131 sinuses of 105 patients. The following three treatment methods were applied to the bony access window: application of a collagen barrier (group CB), repositioning the bone fragment (group RW) and untreated (group UT). Radiographic healing in the window area, augmented bone height changes and marginal bone level changes were examined. Mixed logistic and mixed linear models were analyzed. Over 4.3 ± 1.4 years of follow-up, the implant survival rate was 100% in groups CB and UT, and 96.9% in group RW. The treatment applied to the window did not significantly influence the radiographic healing in the window area, augmented bone height changes or marginal bone level changes (p > 0.05). The healed window areas had generally flat morphologies and were fully corticalized. The mean changes in the augmented bone were less than 1.5 mm in all groups. Marginal bone level changes were minimal. In conclusion, Healing outcomes were not different among three different methods to treat the bony access window in lateral SFE.
本研究的目的是回顾性确定在外侧窦底提升术（SFE）中对骨窗应用不同治疗方法对愈合结果的影响。对105例患者的131个鼻窦进行了外侧窦底提升并植入种植体。对骨窗应用以下三种治疗方法：应用胶原屏障（CB组）、复位骨块（RW组）和不治疗（UT组）。检查窗区的影像学愈合情况、增高骨高度变化和边缘骨水平变化。分析了混合逻辑模型和混合线性模型。在4.3±1.4年的随访中，CB组和UT组的种植体存活率为100%，RW组为96.9%。应用于骨窗的治疗方法对窗区的影像学愈合、增高骨高度变化或边缘骨水平变化没有显著影响（p>0.05）。愈合的窗区形态通常较为平坦，且完全皮质化。所有组增高骨的平均变化小于1.5毫米。边缘骨水平变化极小。总之，在外侧窦底提升术中，三种不同的骨窗治疗方法的愈合结果没有差异。
