- Public TitleHow to treat peri-implantitis?
- Scientific TitleClinical and microbiological evaluation of implant surface decontamination using 35% phosphoric etching gel during surgical treatment of peri-implantitis – a randomized clinical pilot study
- ACRONYM
- hypothesisDecontamination of the implant surface with 35% phosphoric acid during the surgical treatment of peri-implantitis does result in better clinical and microbiological outcome compared to sterile saline
- Healt Condition(s) or Problem(s) studiedPeri-implantitis
- Inclusion criteriaInclusion criteria were:
•≥ 18 years of age;
•at least one endosseous implant with clinical and radiographical signs of peri-implantitis;
•implants were in function for at least two years;
•capable of understanding and providing informed consent.
- Exclusion criteria•Contraindications for the surgical procedures;
•A history of local radiotherapy to the head and neck region;
•Pregnancy and lactation;
•Insuline-dependent diabetes;
•Systemic use of antibiotics during the last 3 months;
•Long-term use of anti-inflammatory drugs;
•Incapability of performing basal oral hygiene measures as a result of physical or mental disorders;
•Uncontrolled periodontitis (PPD > 5mm);
•Implants placed in skin grafted areas;
•Implants with bone loss due to other reasons than bacterial infection (e.g. loose screw, inadequate positioning of the implant);
•Implants with bone loss exceeding 2/3 of the length of the implant or implants with bone loss beyond the transverse openings in hollow implants;
•Implant mobility;
•Implants at which no position can be identified where proper probing measurements can be performed;
•Previous surgical treatment of the peri-implantitis lesions.

- Target number of participants27
- InterventionsPeri-implant lesions were treated with resective surgical treatment consisting of apically repositioned flap, bone recontouring and surface debridement and decontamination. After mechanically cleaning, the implant surfaces were treated with 35% phosphoric etching gel
- Primary outcomePercentage of sites with bleeding on probing (% sites BoP) was used as primary clinical outcome variable
- Secondary outcomeSecondary clinical outcome variables were presence of plaque (% sites plaque), suppuration on probing (% sites SoP), mean PPD and radio-graphical marginal bone loss at baseline. Next to this microbiolical parameters were recorded.

- Brief summaryAn effective intervention protocol for treatment of peri-implantitis is not yet available. The objective of this randomized, double-blinded controlled clinical trial was to assess the clinical, microbiological and radiographical effect of decontamination of the implant surface during surgical treatment of peri-implantitis using 35% phosphoric acid or sterile saline.
