Eligibility
Inclusion criteria
Inclusion criteria: The patient is = 18 years of age; The patient has at least one endosseous implant in the oral cavity with clinical and radiographical signs of peri-implantitis. Peri-implantitis is defined as progressive loss of marginal bone = 2mm, as compared to the baseline radiograph (after placing the definitive restoration) in combination with bleeding and/or suppuration on probing; The implants have been in function for at least two years; The patient is capable of understanding and giving informed consent.
Exclusion criteria
Exclusion criteria: - Medical and general contraindications 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; - 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; - Previous non-surgical treatment of the peri-implantitis lesions during the last 3 months (scaling or curettage) - Chronic bronchitis and asthma - Presents of natural dentition (only for patients in heamatological study)
Design outcomes
Primary
| Measure | Time frame |

Secondary
| Measure | Time frame |
|---|---|
