Abstract

Increased peri-implantitis was identified in patients who had lost teeth through periodontitis, but the evidence is limited.

Studies have yielded inconsistent answers to the question of whether susceptibility to periodontitis affects implant treatment outcome. In this systematic review, from an initial list of 2,116 papers, 547 abstracts were examined, 49 full-text articles were studied, and 2 were finally included in the review.

One study of 346 implants in 97 partially-dentate patients identified definite periodontitis and non-periodontitis groups, each of 25 subjects with respectively 100 and 92 implants. The other study, of 112 implants in 53 patients, yielded respective groups of 8 and 45 patients. At 5 yrs in the first study, 7 patients lost 8 implants in the periodontitis group, and 3 control patients lost 3 implants. In the second study, just one implant was lost, in the control group. These differences were not statistically significant. The only significant differences were that more periodontitis patients had peri-implantitis and greater peri-implant bone loss.
