Abstract

A REVIEW: PERI-IMPLANTITIS – MANAGEMENT

Krishna Mohana Reddy

Dental implants have 89% above survival rate at 10 to 15 yrs, but periimplantitis or dental implant infections may be as high as 14%. Periimplantitis can limit clinical success and impose health and financial burdens to patients and health providers. Pathogenic bacterial species of periodontitis (e.g.: fusobacterium ssp, A.A.comitans, P.gingivalis,) are also associated with peroimplantitis. Incidence of periimplantitis is higher in patient who smokes or poor oral health as well as with calcium phosphate coated or surface roughened implants. Antibiotics have been used in the treatment of periimplantitis as fibers, gels, and beads to deliver the drug. Guided tissue regeneration membranes loaded with anti bacterial preparations are used in osseoreintegration at periimplantitis zone. Experimental approaches include the development of anti-bio-adhesion coatings,(e.g.,vancomycin, ag, zn,) coating surfaces with antimicrobial agents(e.g., calcium phosphate, polylactic acid) or antimicrobial releasing coatings(e.g., calcium phosphate,poly lactic acid, chitosan). Future strategies include the development of surfaces that become antimicrobial in response to infection, and improvements in the per mucosal seal. Research still needed to identify strategies to prevent bacterial attachment and enhance normal cell / tissue attachment to implant surface.
