Treatment of peri-implantitis using platelet-rich fibrin

Surgical Treatment of Peri-implantitis With Adjunctive Application of Platelet Rich Fibrin (PRF) Compared With Open Flap Debridement (OFD) Alone: A 12-month Randomised Clinical Trial

NA · University of Bern · NCT06679283

This study is testing whether adding platelet-rich fibrin to surgery can help people with peri-implantitis heal better and improve bone growth around their dental implants.

What this trial studies

This study investigates the effectiveness of platelet-rich fibrin (PRF) in enhancing the surgical treatment of peri-implantitis, a condition characterized by inflammation and bone loss around dental implants. Participants will undergo open flap debridement either with the adjunctive application of PRF or without it, allowing for a comparison of outcomes. The study aims to assess improvements in bone regeneration and healing in patients with peri-implantitis defects. By evaluating the impact of PRF on treatment outcomes, the research seeks to provide evidence for its use in clinical practice.

Who should consider this trial

Good fit: Ideal candidates include adults with peri-implantitis characterized by specific clinical and radiographic criteria.

Not a fit: Patients with severe systemic diseases, chronic inflammatory conditions, or those who smoke more than five cigarettes may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved healing and regeneration in patients suffering from peri-implantitis, potentially reducing the need for more invasive treatments.

How similar studies have performed: While some studies have shown positive effects of PRF in bone regeneration, evidence specifically for its use in peri-implantitis remains limited, making this approach somewhat novel.
