Biological Risks: Peri-implantitis & Healing

article
Peri-implantitis is an infection that affects the tissue and bone surrounding dental implants. While uncommon, it can occur if bacteria accumulate around the implants over time. The good news is that most cases can be prevented with good oral hygiene, regular professional care and ongoing follow-up after All-On-4 Plus® treatment.

Peri-implantitis is a recognised implant-related complication. It occurs when bacteria cause inflammation around the implant. If left untreated, the inflammation can spread into the surrounding bone and may affect implant stability in the future.
