Influence of Implant Surface Decontamination on the Reconstructive Outcomes of Peri-implantitis

Influence of Implant Surface Decontamination on the Reconstructive Outcomes of Peri-implantitis: A Randomized Clinical Trial

Two groups are aimed at being investigated in three centers (CICOM, Clinica Branemark and Clinica Joan Pi) Test group: Group electrolytic approach (EA): Mechanical detoxification using curettes + NiTi brushes + EA (GalvoSurge) during 2 minutes Control group: Group hydrogen peroxide (HP): Mechanical detoxification using curettes + NiTi brushes + hydrogen peroxide 5% for 2 minutes soaked in a gauze Patients´ group selection will be randomly allocated. For patients whom their personal clinical record # ends in a number from 0 to 4 will be included in the test group, while for patients whom their personal clinical record # ends from 5-9 will be included in the control group. The infra-osseous component will be regenerated using xenograft (Creos, NB) + autogenous bone in a ratio 1:1 harvested from the adjacent area. A resorbable membrane (Creos, NB) will be placed to compartmentalize the infra-osseous component following a poncho-like approach.

Surface decontamination of infected implants followed by reconstructive therapy to manage peri-implantitis

Inclusion: Screw-retained or cement-retained fixed or removable implant-supported prosthesis for a minimum of 36 months. All patients in age of 18 to 80 non-smokers no presence of systemic disease or medication known to alter bone metabolism partial or complete edentulous patients that have no active periodontal disease. Exclusion criteria: pregnancy or lactation history of or current smokers uncontrolled medical conditions, lacking keratinized mucosa (≤2mm) on the lingual or buccal implant sites, advanced(A) peri-implantitis (>50% of the implant length).
