Clinical and radiographic evaluation of peri-implantitis treatment: case series 

The aim of this case series was to describe the clinical and radiographic follow-up of four patients with treated peri-implantitis.

Method:

Four patients treated for peri-implantitis involving a total of 6 implants, were followed-up for a 46 months to 6,5 years period. All cases presented suppuration, bleeding-on-probing and peri-implant bone loss. After diagnostic, the first non-surgical treatment phase comprised hygiene individual procedures, mechanical debridement and local application of antiseptics (chlorhexidine gel 0,2%, Elugel®, Pierre Fabre) and antibiotics (mincocycline). In case of persistence of clinical signs and/or pocket depth ≥ 5 mm a second phase, surgical, with mechanical debridement, surface decontamination with antiseptics and antibiotics and xenograft (Bio-Oss®. Geistlich, Switezerland) bone regeneration was performed. In the subsequent clinical and radiographic follow-up period, all cases showed improvement in the clinical evaluation parameters and none implant was lost.

Result:

There is little reliable evidence about the most effective intervention for peri-implantitis therapy. According to some authors , the adjunctive use of local antiseptics,

antibiotics and bone-substitutes can improve clinical parameters. Our results, based on clorohexidine/minocycline applications and, when needed, on bone regeneration with xenografts are in agreement with these conclusions.

Conclusion:

Within the limitations of this limited case series, we conclude that it seems possible to successfully treat periimplantitis disease on a medium and long term basis.
