Clinical, microbiological and radiographical evaluation of implant surface decontamination using air-polishing in the surgical treatment of peri-implantitis; a randomized controlled trial
- Conditions
- Peri-implantitisPeri-implantitis is diagnosed by signs of inflammation (bleeding and/or suppuration on probing) and radiographically by progressive loss of supporting bone around dental implants.

The patient is = 18 years of age;
- The patient has at least one endosseous implant in the oral cavity with remaining clinical and radiographical signs of peri-implantitis. Peri-implantitis is defined as probing pockets depths (PPD) of = 5mm in combination with bleeding and/or suppuration on probing and radiographic bone loss = 2 mm after placing the definitive restoration (Lang and Berglundh 2011).
-The implants have been in function for at least two years;
-The patient is capable of understanding and giving informed consent.
-Medical and general contra-indications for the procedures;
-A history of local radiotherapy to the head and neck region;
-Pregnancy and lactation;
-Uncontrolled diabetes mellitus (HbA1c > 7% or > 53 mmol/mol);
-Use of antibiotics during the last 3 months;
-Known allergy to chlorhexidine;
-Long-term use of anti-inflammatory drugs;
-Incapability of performing basal oral hygiene measures as a result of physical or mental disorders;
-Active periodontal disease at remaining dentition (PPD=6mm, bleeding=20%) and/or insufficient oral hygiene (plaque=20%)
-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;
-Chronic bronchitis and asthma

- Primary Outcome Measures
Name Time Method The primary objective of this controlled clinical study is to evaluate the clinical effect of decontamination of the implant surface during a resective surgical treatment of peri-implantitis using air-polishing or handinstrumentation.
- Secondary Outcome Measures
Name Time Method The secondary objectives are to assess the microbiological and radiographical effect of decontamination of the implant surface during the surgical treatment of peri-implantitis using air-polishing or hand instruments.
