This presentation will address peri-implantitis, a plaque-associated disease around implants that leads to inflammation and progressive bone loss. The prevalence of the condition, affecting up to one in five implants, will be outlined together with the main causes, including bacterial biofilm, smoking, systemic disease, poor hygiene, and prosthetic factors. The disease process will be described, showing how the host response to microbial challenge results in pocket formation and bone resorption similar to periodontitis.
