The aim of this retrospective study was to evaluate the long-term performance of the supercritical CO (Supercrit, BIOBank) viral-inactivated bone allografts in maxillary sinus augmentation. Thirty-four consecutive patients underwent 50 maxillary sinus augmentation procedures, and 103 implants were placed. At a mean of 8.8 years after graft surgery, 95 implants were well osseointegrated and functioning. Eight implants failed, and the overall implant survival rate at 10 years was 92.2%. The marginal bone loss averaged 1.2 ± 1.3 mm. Within the limitations of this study, the supercritical CO viral-inactivated bone allograft is a valuable bone graft material, achieving long-term satisfying outcomes when used alone.
本回顾性研究旨在评估超临界 CO（Supercrit，BIOBank）病毒灭活骨同种异体移植物在上颌窦提升中的长期性能。34 例连续患者接受了 50 例上颌窦提升手术，共植入 103 枚种植体。在移植物手术后平均 8.8 年时，95 枚种植体具有良好的骨整合和功能。8 枚种植体失败，10 年时的总体种植体存活率为 92.2%。平均边缘骨吸收量为 1.2±1.3mm。在本研究的限制范围内，超临界 CO 病毒灭活骨同种异体移植物是一种有价值的骨移植材料，单独使用时可获得长期满意的效果。
