An xray 2 years after placement then 7 years later in a heavy smoker. Shows progression of peri-implantitis
Peri-implantitis is the destructive inflammatory process affecting the soft and hard tissues surrounding dental implants. The array of periodontal pathogens found around failing implants (those affected by peri-implantitis) are very similar to those found in association with various forms of periodontal disease. In compound implants (two stage implants), between the actual implant and the superstructure (abutment) are gaps and cavities into which germs can penetrate from the oral cavity. Later these germs will return into the adjacent tissue and can cause periimplantitis. As prophylaxis these implant interior spaces should be sealed.
