PURPOSE
Platelet-rich fibrin (PRF) has been recently used as the sole grafting material in sinus floor elevation procedures. The aim of this prospective study was to measure the bone gain around the dental implant after using the crestal approach to sinus floor elevation using platelet-rich fibrin as the only grafting material in atrophic posterior maxillae with residual bone height <5 mm.
MATERIALS AND METHODS
Two different types of implants were used: hydroxyapatite (HA) and sandblasted acid-etched (SA) implants. Panoramic radiography and computed tomography were used to measure the endosinus bone gain.
RESULTS
Twenty-seven patients with 39 implants (19 HA and 20 SA) were included in this study. The mean residual bone measurements before surgery in the SA and HA groups were 2.85 and 2.68 mm, respectively. The mean average bone gains for 1 year in the SA and HA groups were 4.38 and 4.00 mm, respectively.
CONCLUSION
This prospective study showed that platelet-rich fibrin promoted endosinus bone gain when used as the grafting material in the crestal approach to sinus floor elevation.
目的
富血小板纤维蛋白（PRF）最近已被用作窦底提升手术中的唯一移植材料。本前瞻性研究的目的是在萎缩性上颌后牙区剩余骨高度<5mm的情况下，使用富血小板纤维蛋白作为唯一移植材料，采用嵴顶入路进行窦底提升后，测量牙种植体周围的骨增量。
材料与方法
使用两种不同类型的种植体：羟基磷灰石（HA）种植体和喷砂酸蚀（SA）种植体。采用全景X线摄影和计算机断层扫描测量窦内骨增量。
结果
本研究纳入了27例患者的39枚种植体（19枚HA种植体和20枚SA种植体）。SA组和HA组术前的平均剩余骨测量值分别为2.85mm和2.68mm。SA组和HA组1年的平均骨增量分别为4.38mm和4.00mm。
结论
这项前瞻性研究表明，在嵴顶入路的窦底提升术中，富血小板纤维蛋白作为移植材料可促进窦内骨增量。
