Peri-implantitis Peri-implantitis is diagnosed by signs of inflammation (bleeding and/or suppuration on probing) and radiographically by progressive loss of supporting bone around dental implants.
Conditions
Interventions
All patients with peri-implantitis will be treated in a surgical way. Before surgical exposure of the affected implants suprastructures will be removed if reasonably possible. Granulation tissue will

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 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.
Exclusion criteria
Exclusion criteria: - 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
