Summary

This study follows 34 people who had treatment for severe gum disease around dental implants (peri-implantitis). Researchers want to see if the disease comes back or gets worse over 3 years. Participants will have a dental exam and X-ray at one follow-up visit. The goal is to learn how well the treatments hold up long-term.
