The aim of this study was to evaluate the 5 year clinical results of maxillary sinus floor augmentation using bovine bone grafts with simultaneous implant placement.
A total of 28 patients were enrolled in the study, and a total of 84 implants were placed into the grafted sites. Unilateral or bilateral sinus augmentation was performed, and implants were inserted into the augmented sinuses. After osseointegration and insertion of the prosthesis, the implants were evaluated by clinical and radiographic parameters.
The cumulative implant survival rate after 60 months of loading was 100%. Periimplant bone loss was at clinically acceptable levels (0.146 and 0.34 mm after 1 and 5 years, respectively).
Bovine bone grafts used in 1-stage sinus augmentation yields sufficient quality and volume of bone for predictable simultaneous implant placement.
本研究旨在评估同期植入种植体的牛骨移植上颌窦底提升术的 5 年临床效果。
共纳入 28 例患者，共植入 84 枚种植体。行单侧或双侧窦底提升术，将种植体植入提升的窦腔。在骨整合和植入修复体后，通过临床和影像学参数对种植体进行评估。
加载 60 个月后，累计种植体存活率为 100%。种植体周骨丢失处于临床可接受水平（分别为 1 年和 5 年时的 0.146 和 0.34 毫米）。
在 1 期窦底提升术中使用牛骨移植物可获得足够的骨质量和体积，从而实现可预测的同期种植体植入。
