Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 to 80 with at least one implant diagnosed with peri-implantitis or healthy implants.

Probably not a fit

Patients with implant mobility or those who smoke may not benefit from this study.

What this trial studies

This study aims to evaluate the effectiveness of two different surgical protocols for treating peri-implantitis over a one-year period. It will assess clinical, radiographic, and microbiological outcomes, as well as patient satisfaction following treatment. The study will also compare microbiological results between implants diagnosed with peri-implantitis and healthy implants. Participants will undergo either implantoplasty or treatment with an erythritol air-abrasive device as part of their intervention.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients suffering from peri-implantitis.

How similar studies have gone: Previous studies have shown varying degrees of success with surgical interventions for peri-implantitis, but this specific comparison of methods is relatively novel.
