An ABCD of Peri-implantitis

The scientific literature is increasingly reporting long-term, severe, destructive peri-implant bone loss in as many as 65% of cases after several years. Widely accepted aetiology includes factors such as poor oral hygiene, flossing, superstructure material, implant connection, poor mechanical loading and medical comorbidities such as diabetes mellitus, long term treatment with corticosteriods, radiation and chemotherapy. This presentation considers new factors in the aetiology of peri-implant bone destruction and implicates the surface characteristics of implants and the knowledge that human jaw bone is not sterile and, in fact, hosts permanent, resident biofilm communities that range from healthy, diverse, stable, resistant and resilient communities to communities that are highly pathogenic.
