Brief Summary:
The goal of this clinical trial is to evaluate the effectiveness of sinus floor elevation using platelet-rich fibrin (PRF) compared to a graftless approach in adult patients with atrophic posterior maxilla (residual bone height 5-7 mm) requiring dental implant rehabilitation. The main questions it aims to answer are:
Does PRF enhance bone height gain more effectively than graftless sinus elevation? Does PRF improve implant stability and reduce marginal bone loss compared to the graftless approach? Researchers will compare the outcomes of PRF-grafted implants versus non-grafted implants to see if PRF improves radiographic and clinical results in single-stage implant placement.
Participants will:
Undergo internal sinus lift via crestal drilling approach
Be randomly assigned to one of two groups:
Group I: sinus lift without graft material Group II: sinus lift with PRF as the sole grafting material Receive simultaneous dental implant placement during the sinus lift Be monitored through clinical exams and radiographic imaging over 6 months postoperatively

Detailed Description:
This randomized controlled clinical trial investigates the clinical and radiographic outcomes of crestal sinus floor elevation in the atrophic posterior maxilla, comparing two approaches: one using platelet-rich fibrin (PRF) as a sole grafting material and another performed without any grafting material. Both interventions are combined with single-stage dental implant placement. The rationale for this study is based on emerging evidence suggesting that graftless techniques, relying on blood clot stabilization and tenting of the sinus membrane, may be sufficient to induce predictable bone formation, especially when residual alveolar bone height is ≥5 mm.
The study involves adult patients presenting with edentulous posterior maxillary regions and limited vertical bone height due to sinus pneumatization and ridge resorption.
Participants are randomly allocated to either PRF or graftless groups. Both groups undergo transcrestal sinus elevation through sequential osteotomy, followed by immediate implant placement under a standardized surgical and prosthetic protocol.
Primary outcomes include radiographic bone gain and implant stability quotient (ISQ), while secondary outcomes include marginal bone loss and peri-implant clinical parameters. Radiographic evaluation is conducted using CBCT imaging at baseline and 6 months postoperatively. This study aims to provide evidence on whether PRF offers added clinical benefit over natural healing and clot formation in sinus lift procedures performed via the less invasive crestal approach.
