Essential Domains, Core Outcome Sets, and Measurements to Capture the Benefits and Harms of Implant Dentistry Interventions: The ID-COSM Initiative

Consensus on a valid and comprehensive set of outcomes to capture the full benefits and harms of implant dentistry interventions is key for progressing toward better clinical guidelines and policy. In this field, research remains fragmented and uses too many different outcomes. Studies are unable to cover the full breadth necessary to properly evaluate benefits, harms, and costs. Best-practice examples inspired the Implant Dentistry Core Outcome Set and Measurements (ID-COSM) initiative that identified four core outcome domain areas (pathophysiology, implant/prosthesis lifespan, life impact, and access to care), five essential outcomes mandatory for all trials, and six outcomes mandatory in specific circumstances. This innovative multistep approach combined input from scientific evidence, patients from multiple countries, methodologists, and industry representatives. The ID-COSM consensus aspires to contribute to better adoption of relevant and valid outcomes in trials and enable their results to be combined in high-quality meta-analyses to support better-informed care and policy.
