MACROPHAGE POLARIZATION IN ASEPTIC BONE RESORPTION AROUND DENTAL IMPLANTS INDUCED BY TI PARTICLES IN A MURINE MODEL
Bone loss around dental implants leads to implant failure
Is bone loss triggered by leakage of titanium (Ti) particles from the implant, and if so, what is the mechanism?
Bone loss
Ti particles + clodronate
Ti particles + empty liposomes
Ti particles + PBS
PBS control
Ti implanted in Sprague Dawley rats
Analysis of implants
Ti increases inflammatory M1 macrophages, pro-inflammatory cytokines, and bone loss
Inflammatory cytokines and bone loss induced by Ti particles were reduced upon depletion of macrophages by clodronate
