From Periodontitis to Periimplantitis—the Quest for the Missing Link

In this narrated review, we shall study the commonality and discord in the anatomy, bacterial flora, immune response, rate of progression, and response to therapy. Finally, we shall explore the unique, periimplantitis-related risk factors. The absence of PDL around implants, combined with poor periimplant vascularization and weaker attachment apparatus, might account for the poor cellular response to bacterial implant in periimplantitis. Using...
