Comparative Evaluation of the Effect of UV Photofunctionalization and i-PRF Biofunctionalization on Osseointegration of Dental Implants: A Clinical and Radiographic Study | Dental implants have become a reliable solution for restoring missing teeth, with long-term success largely dependent on achieving and maintaining osseointegration. Despite the high success rates reported, implant failures are still observed, commonly due to inadequate osseointegration or peri-implant infections. To improve outcomes, various surface modification strategies have been developed. UV treatment enhances protein adsorption, osteoblast attachment, and bone formation, thereby accelerating and improving osseointegration. On the other hand, biological approaches such as injectable platelet-rich fibrin (i-PRF) provide a biofunctionalization method that delivers autologous growth factors, including platelet-derived growth factor and vascular endothelial growth factor, which promote angiogenesis and osteogenesis. | Completed |
