A recent study has examined the efficacy of peri-implantitis treatment over a period of five years. The study analysed the results of 107 patients who received treatment for the disease.

Peri-implantitis occurs in roughly 10% of implants and 20% of patients, and is a growing concern in the field of implant dentistry. Numerous risk factors have been identified, including poor plaque control, smoking and peri-implant cement residue. The study used the following strategy for treating peri-implantitis: pre-treatment phase with professional tooth cleaning; surgical phase; post-surgical phase. This was followed by regular maintenance visits.

107 patients with 158 implants were included in the study. Each patient had received implants from the same surgeon, placed between 1993 and 2014.

Over the course of 56 months after therapy, plaque index, full-mouth bleeding and probing pocket depth were analysed. The implants which received treatment for peri-implantitis experienced a survival rate of 90.5%. The researchers suggest that regular clinical monitoring and reinforcement of oral hygiene can contribute to long-term success.

The researchers concluded that it is possible to treat peri-implantitis successfully. Favourable results depend on a treatment approach which is based on defect morphology and the enrolment of patients in a strict maintenance programme.
