The purpose of this study was to evaluate the predictability of new bone formation in the maxillary sinus using an autologous fibrin-rich blocks with concentrated growth factors (CGFs) alone as an alternative to graft material.
A total of sixty-one sinus grafts were consecutively performed using the lateral window approach. After making replaceable bony window, the sinus membrane was elevated to make a new compartment. After 113 implants (average 13 mm high) with 11 different systems were placed simultaneously, the collected fibrin-rich blocks with CGFs alone were inserted in the sinus. To seal the lateral window, the bony window was repositioned. Radiographic, clinical, and histologic evaluation was performed to verify sinus augmentation.
No significant postoperative complications developed. New bone consolidation in all augmented maxillary sinus was observed along the implants on plain radiographs and on cone-beam computed tomograms. The success rate of implant was 98.2% after an average of 10 months loading.
Fibrin-rich blocks with CGFs act as an alternative to bone grafting and can be a predictable procedure for sinus augmentation.
本研究旨在评估单独使用富含纤维蛋白的自体浓缩生长因子（CGF）块在替代移植物材料方面预测上颌窦新骨形成的能力。
共连续进行了 61 例鼻窦植骨术，采用外侧开窗法。制作可替换骨窗后，抬起窦膜以形成新的隔室。同时放置 11 种不同系统的 113 个种植体（平均高度为 13mm）后，单独将收集的富含纤维蛋白的 CGF 块插入窦内。为了密封外侧窗口，重新定位骨窗。进行影像学、临床和组织学评估以验证鼻窦增骨。
无明显术后并发症。在普通放射片和锥形束计算机断层扫描上，所有增强的上颌窦中都观察到沿种植体的新骨整合。在平均 10 个月的负重后，种植体的成功率为 98.2%。
富含纤维蛋白的 CGF 块可替代骨移植，是一种可预测的鼻窦增大术。
