Historically, diagnosing peri-implantitis is done based on whether the disease is present, evaluated using the arbitrary thresholds of probing depths and bone loss. Using this approach as a tool to ascertain meaningful information regarding prevalence and treatment is limited. Efforts have been made to improve upon this, but to date, only one of these classifications has provided a simple method to communicate disease severity based on the amount of bone loss. A modified version of this simplified classification is proposed here, including information regarding the implant position, as emerging information suggests that this is a crucial factor in the etiology and prognosis of peri-implantitis. This enhancement to the classification better serves both researchers and clinicians in their discussion about peri-implantitis and helps to determine and recommend the most effective methods of management.
