Abstract：
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

摘要：
■种植牙的康复已成为最广泛接受的修复天然牙齿的治疗方案。直接鼻窦提升是增加不足的上颌后脊的最可预测的程序之一。
■该研究是针对骨骼不足的患者设计的，用于上颌后脊的植入物。试验组仅接受富血小板纤维蛋白作为填充剂,对照组接受同种异体骨移植。残余骨高度（RBH），植入物的移动性，对比分析组间及组内软组织特征。
■两组在RBH上都有相当大的收获，组内分析显示两组的临床骨高度增加，测试组表现出统计学上的显着增益，从z=-3.477的6个月和0.001至9个月的p值，z=-3.531和0.027的p值。
■结果表明，单独使用富血小板纤维蛋白可改善骨骼再生，从而实现植入物治疗成功所需的窦底的可预测和稳定的增大。
