Peri-implantitis
Conditions
Interventions
All patients receive extensive oral hygiene instructions (using an electric toothbrush, interdental brushes and floss (Oral-B® superfloss or Meridol® floss, at implants in the esthetic zone only) and

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 (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 contraindications for the procedures; - A history of local radiotherapy to the head and neck region; - Uncontrolled diabetes (HbA1c 5 mm); - 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 treatment of the peri-implantitis lesions during the last 3 months (scaling or curettage)
