本研究的目的是评估，使用临床和放射学评估，牙种植体的稳定性5年后上颌窦底提升与磷酸八钙-胶原复合物（OCP/Col）。上颌窦底提升是通过侧窗入路进行的。根据宿主骨的高度，采用同步入路（≥5 mm）或分期入路（小于5 mm）。主要结局是评价临床牙种植体状况，如感染、牙种植体炎、牙种植体稳定性、疼痛和感觉异常。次要结果是评估增加的骨体积、增加的骨体积变化率、垂直骨高度和牙种植体固定装置周围的边缘骨丢失。在整个随访期间，所有牙种植体的情况均无异常。OCP/Col衍生新骨成熟后，增强骨体积和增强骨体积的变化率基本不变。术后1年和5年，模拟入路的新骨体积变化率为21.9%，分期入路的新骨体积变化率为16.8%。术后1 ~ 5年，同期入路的垂直骨高度降低率为7.1%，分期入路为7.5%。术后5年，同期入路的平均边缘骨丢失为1.76 mm，分期入路为0.50 mm。总之，通过临床和影像学评价，明确了OCP/Col种植术进行窦底提升后5年的牙科种植体成功率。
The purpose of this study was to evaluate, using clinical and radiological assessments, the stability of dental implants 5 years after maxillary sinus floor augmentation with octacalcium phosphate–collagen composite (OCP/Col). Maxillary sinus floor augmentation was performed through a lateral window approach. Depending on the height of the host bone, a simultaneous approach (≥5 mm) or a staged approach (less than 5 mm) was employed. The primary outcome was the evaluation of clinical dental implant conditions such as infection, peri‐implantitis, dental implant stability, pain, and paresthesia. Secondary outcomes were the evaluation of the augmented bone volume, change rate of augmented bone volume, vertical bone height, and marginal bone loss around dental implant fixture. The conditions of all dental implants were uneventful throughout the follow‐up period. Augmented bone volume and changing rate of augmented bone volume were essentially unchanged following maturation of the OCP/Col‐derived new bone. The change rate of new bone volume was 21.9% in the simulated approach and 16.8% in the staged approach at 1 year and 5 years postoperatively. The reduction rate in vertical bone height was 7.1% in the simultaneous approach and 7.5% in the staged approach between 1 year and 5 years postoperatively. Mean marginal bone loss was 1.76 mm with the simultaneous approach, and 0.50 mm with the staged approach at 5 years postoperatively. In conclusion, the success of dental implants 5 years after sinus floor augmentation by OCP/Col implantation was clarified by both clinical and radiological evaluations.
