Rehabilitation with dental implants has become the most widely accepted treatment protocol for rehabilitation of lost natural teeth. Direct sinus lift is one of the most predictable procedures for augmenting the deficient posterior maxillary ridges.
The study was designed in patients with insufficient bone for implants in the maxillary posterior ridges. The test group received platelet-rich fibrin alone as filler, and the control group received a bone allograft. The residual bone height (RBH), implant mobility, and soft tissue characteristics between and within the groups were compared and analyzed.
Both the groups had considerable gain in RBH, and the intragroup analysis revealed clinical gain in bone height in both the groups, with the test group exhibiting statistically significant gain which kept on improving from 6 months with z= -3.477 and a p value of 0.001 to 9 months with z=-3.531 and a p value of 0.027.
The results suggest that the use of platelet-rich fibrin alone improves the bone regeneration, thereby achieving predictable and stable augmentation of the sinus floor required for the success of implant therapy.
牙种植体修复已成为修复缺失天然牙最广泛接受的治疗方案。直接上颌窦提升术是增加上颌后牙区骨量不足最可预测的手术之一。
该研究针对上颌后牙区骨量不足以植入种植体的患者进行设计。试验组仅接受富血小板纤维蛋白作为填充材料,对照组接受同种异体骨移植。对两组之间及组内的剩余骨高度(RBH)、种植体松动度和软组织特征进行比较和分析。
两组的RBH均有显著增加,组内分析显示两组的骨高度均有临床增加,试验组表现出统计学上的显著增加,从6个月时z = -3.477,p值为0.001到9个月时z = -3.531,p值为0.027,且持续改善。
结果表明,单独使用富血小板纤维蛋白可改善骨再生,从而实现种植治疗成功所需的上颌窦底可预测且稳定的增高。
