Dental Implant Survival Rate

This study is a medium-term (6-9 years) follow-up of the health of the tissues surrounding the implant which was treated for peri-implantitis (peri-implant infection) in an already completed study with a 12 month follow-up. Patients who were treated in a randomised controlled trial with a 12 month follow-up will be invited to attend for examination of the implant and an x-ray to assess the bone levels at the implant. Participants will be asked to complete a questionnaire about their overall satisfaction following treatment.
