目的：本研究的目的是评估使用富血小板纤维蛋白（PRF）作为唯一移植材料同时植入种植体的窦底增强术。材料和方法：本研究纳入了 2009 年 7 月至 2011 年 1 月期间在长崎大学医院口腔颌面外科接受上颌窦底提升术并同时植入种植体并使用 PRF 作为唯一填充材料的患者。对每位患者进行术前和术后（术后 6 个月）放射线照相和计算机断层扫描，以评估植入部位的骨形成。使用种植规划软件（Simplant、Materialise Dental）测量新形成骨的密度（以亨斯菲尔德单位 [HU] 为单位）以及从窦底到插入种植体的牙槽嵴的骨高度。结果：进行了 9 次窦底增强术，并在 6 名患者体内植入了 17 个种植体。手术前窦底和牙槽嵴之间的平均残余骨高度为 4.28 +/- 1.00 mm（范围，1.9 至 6.1 mm），术后为 11.8 +/- 1.67 mm（范围，9.1 至 14.1 mm）。在所有情况下，牙槽骨脊都足够宽，可以进行种植体植入。种植体周围新生长骨的平均密度为 323 +/- 156.2 HU（范围：185 至 713 HU）。所有种植体在插入基台时（即上颌窦提升后 6 个月）均处于临床稳定状态。结论：上颌窦抬高同时使用 PRF 作为唯一填充材料进行种植体植入可能会促进自然骨再生。
Purpose: The objective of this study was to evaluate sinus floor augmentation with simultaneous implant placement using platelet-rich fibrin (PRF) as the only grafting material. Materials and Methods: This study included patients who underwent sinus floor augmentation with simultaneous implant placement using PRF as the sole filling material between July 2009 and January 2011 at the Department of Oral and Maxillofacial Surgery, Nagasaki University Hospital. For each patient, presurgical and postsurgical (6 months after the surgery) radiography and computed tomographic scanning were performed to assess bone formation at the implant sites. The density (in Hounsfield units [HU]) of the newly formed bone and the bone height from the sinus floor to the alveolar crest where implants were inserted were measured using implant planning software (Simplant, Materialise Dental). Results: Nine sinus floor augmentations were performed, and 17 implants were placed in six patients. The mean residual bone height between the sinus floor and alveolar crest was 4.28 +/- 1.00 mm (range, 1.9 to 6.1 mm) prior to surgery and 11.8 +/- 1.67 mm (range, 9.1 to 14.1 mm) after surgery. The alveolar bone ridge was wide enough for implant placement in all cases. The mean density of the newly gained bone around the implants was 323 +/- 156.2 HU (range, 185 to 713 HU). All implants were clinically stable at the time of abutment insertion, 6 months after sinus augmentation. Conclusion: Sinus elevation with simultaneous implant placement using PRF as the only filling material may promote natural bone regeneration.
