Risk for peri-implant diseases and defects: Report of workgroup 1 of the joint AO/AAP consensus conference on prevention and management of peri-implant diseases

Background

A consensus meeting on peri-implant diseases and treatment was initiated by the American Academy of Periodontology (AAP) and the Academy of Osseointegration (AO) with the goal of developing subject- and site-level risk profiles for peri-implant diseases and defects, and risk-informed treatment recommendations. This report summarizes the conclusions of Working Group 1.

Methods

Working Group 1 evaluated the risk for peri-implant diseases and defects based on four commissioned systematic reviews, followed by an in-person workshop to discuss the reviews and the inferences.

Results

Several factors emerged as risk markers for peri-implant mucositis, peri-implantitis, as well as for soft and hard tissue discrepancies and defects in the absence of disease.

Conclusion

Patient- and site-level factors can increase the odds of developing peri-implant disease or defects in soft tissue and marginal bone surrounding clinically healthy implants. Risk-informed treatment recommendations were made by the panel of experts.

Key points

• This consensus estimates risk based on both patient and site-level factors.
• Consideration must be given to modifiable and non-modifiable risk factors, and treatment modified accordingly.
• There is a lack of primary research on several topics that were considered by the consensus panel, and several gaps in knowledge still continue to exist.
