Effects of occlusal forces on the peri‐implant‐bone interface stability

Abstract The occlusal forces and their influence on the initiation of peri‐implant bone loss or their relationship with peri‐implantitis have created discussion during the past 30 years given the discrepancies observed in clinical, animal, and finite element analysis studies. Beyond these contradictions, in the case of an osseointegrated implant, the occlusal forces can influence the implant‐bone interface and the cells responsible for the bone remodeling in different ways that may result in the maintenance or loss of the osseointegration. This comprehensive review focuses on the information available about the forces transmitted through the implant‐crown system to the implant‐bone interface and the mechano‐transduction phenomena responsible for the bone cells’ behavior and their interactions. Knowledge of the basic molecular biology of the peri‐implant bone would help clinicians to understand the complex phenomenon of occlusal forces and their effects on the implant‐bone interface, and would allow better control of the negative effects of mechanical stresses, leading to therapy with fewer risks and complications.
