The present study was done to evaluate the efficacy of platelet-rich fibrin (PRF) with bovine bone graft (Bio-Oss™) in direct sinus augmentation for simultaneously dental implant placement.
The study included 14 patients who fulfill the inclusion criteria, among them 10 were male and 4 were female with PRF with Bio-Oss™. For each patient, bone level was assessed preoperatively and postoperatively after 1, 6, and 12 months with a panoramic X-ray and radiovisiography to evaluate the vertical bone height from the shoulder of the implant to the most apical end.
The outcome of the sinus lift and the implants placed was evaluated periodically at 1, 6, and 12 months postoperatively. All the patients underwent two-stage procedures. At the end of 20 week, implants were exposed; radiological parameters were assessed again for implant integration, and prosthetic rehabilitation was started after 2 weeks and it was completed by the end of 24 weeks (6 months postoperatively). Twelve months postoperatively, the endosinus bone gain noted was 7 mm, which indicated the use of PRF with bovine bone graft as a reliable filling material during simultaneous sinus lift and implantation.
PRF with bone graft (Bio-Oss) is used as an augmentation material after direct maxillary sinus lift, and the resulting bone formation was adequate for placement of dental implant.
本研究旨在评估富含血小板纤维蛋白(PRF)联合牛骨移植材料(Bio-Oss™)在直接上颌窦提升同期植入牙种植体中的疗效。
本研究纳入14例符合纳入标准的患者,其中男性10例,女性4例,采用PRF联合Bio-Oss™。对每位患者在术前以及术后1个月、6个月和12个月时进行全景X线片和数字化X线体层摄影检查,评估种植体肩部至最根尖端的垂直骨高度。
术后1个月、6个月和12个月定期评估上颌窦提升及种植体植入的效果。所有患者均接受两阶段手术。在20周结束时,暴露种植体;再次评估放射学参数以判断种植体的整合情况,2周后开始进行修复治疗,并在24周结束时(术后6个月)完成。术后12个月,上颌窦内骨增量为7mm,这表明在同期上颌窦提升和种植术中,PRF联合牛骨移植材料是一种可靠的填充材料。
PRF联合骨移植材料(Bio-Oss)可用于直接上颌窦提升术后的骨增量,所形成的骨量足以植入牙种植体。
