To assess the radiographic outcomes, complications, and implant survival rates of advanced platelet-rich fibrin versus xenografts in hydraulic sinus floor elevation.
In this randomized trial, 40 patients with 46 implants were divided into two groups: a test group (advanced platelet-rich fibrin alone) and a control group (xenograft alone). The key outcome measures included bone regeneration, implant survival, and complications.
Both groups achieved 100% implant survival. One case of maxillary sinus infection occurred in the control group after surgery. There was no significant difference in bone regeneration between the two groups at 6 months post-surgery and 12 months post-load (P > 0.05). The residual bone height and sinus width at the apex of the implant were significant negative predictors of bone regeneration (P < 0.05), whereas the presence of adjacent teeth was a significant positive predictor (P < 0.05).
Both advanced platelet-rich fibrin and xenografts effectively enhanced bone growth at sinus floor elevation, achieving high implant survival rates over one year. Advanced platelet-rich fibrin alone may be a viable xenograft alternative, necessitating further long-term studies to confirm its efficacy. The study was registered in the Chinese Clinical Trial Registry (http://www.chictr.org.cn/) with the registration number ChiCTR2100042060. This clinical trial was not registered before participant recruitment or randomization.
