Objective: This treatment concept paper introduces a risk assessment tool, the Implant Disease Risk Assessment, (IDRA) which estimates the risk for a patient to develop peri-implantitis.
Materials And Methods: The functional risk assessment diagram was constructed incorporating eight parameters, each with documented evidence for an association with peri-implantitis.
Results: The eight vectors of the diagram include (1) assessment of a history of periodontitis (2) percentage of sites with bleeding on probing (BOP) (3) number of teeth/implants with probing depths (PD) ≥5 mm (4) the ratio of periodontal bone loss (evaluated from a radiograph) divided by the patient's age (5) periodontitis susceptibility as described by the staging and grading categories from the 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases (Journal of Periodontology, 89 Suppl 1, S159-S172, 2018) (6) the frequency/compliance with supportive periodontal therapy (7) the distance in mm from the restorative margin of the implant-supported prosthesis to the marginal bone crest and (8) prosthesis-related factors including cleanability and fit of the implant-supported prosthesis.
Objectives: To evaluate clinical outcomes of supportive peri-implant therapy (SPIT) following surgical treatment of peri-implantitis.
Materials And Methods: Twenty-four partially dentate patients with 36 dental implants diagnosed with peri-implantitis were treated by an anti-infective surgical protocol followed by regular supportive therapy. SPIT included removal of supra- and submucosal biofilm at the treated implants using titanium or carbon fibre curettes, or ultrasonic devices.
