What this trial studies

An international consortium will recruit 100 adults with advanced peri-implantitis (20 per partner site) to collect clinical data and blood samples at five European university centers. Eligible participants must have pocket depths >6 mm, positive bleeding on probing, and bone loss exceeding 66% on at least one implant surface. Collected blood will be analyzed for immunological markers and levels of titanium or other metal ions to compare two leading theories of peri-implantitis origin: bacterial invasion versus an immune reaction to metallic particles. Each partner site will obtain local ethics approval and perform procedures at its clinical facility.

Who should consider this trial

Good fit: Adults with active, advanced peri-implantitis (pocket depth >6 mm, positive BoP, and >66% bone loss at an implant) who can attend one of the participating European centers and are not pregnant or taking antiresorptive medications are ideal candidates.

Not a fit: People with mild or stable peri-implant conditions, pregnant individuals, or those with a history of bisphosphonate or other antiresorptive use or surgical contraindications are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the project could identify blood markers or metal signals that help guide diagnosis, prevention, or personalized treatment for peri-implantitis.

How similar studies have performed: Prior research has reported local immune responses and titanium particle associations with peri-implantitis, but clinical evidence from blood-based multicenter studies is limited, making this consortium approach relatively novel.
