Implant Disease Risk Assessment IDRA – a tool for preventing peri-implant disease

Heitz –Mayfield LJA, Heitz F, Lang NP. Clin Oral Impl Res. 2020;31:397–403. 

Compiled by Dr Aaron Martin and Dr Sarah Chin


A number of periodontal risk assessment tools for periodontitis have been developed and validated. One such tool, the Periodontal Risk Assessment (PRA) (Lang and Tonetti 2003), has been used in nine studies. These studies showed high-risk patients in maintenance or supporting periodontal therapy (SPT) were identified by the criteria of PRA for having re-infection and progression. The PRA is available online and is used widely by the profession, with more than 500 hits per day.

The Implant Disease Risk Assessment (IDRA) has been developed for the purpose of decreasing peri-implantitis risk. An understanding of the main aetiological factors documented in the literature may be used to improve the outcomes of implant therapy. The IDRA can be used as a risk-evaluation tool for partially dentate patients and, with limitations, for edentulous patients.

Eight factors were identified from recent studies addressing the risk factors for implant biological complications. These factors may contribute to the development of peri-implantitis. Control of these factors may also reduce the development of biological complications.
