The Influence of Surface Roughness on the Displacement of Osteogenic Bone Particles during Placement of Titanium Screw-Type Implants

Abstract

The present study, for the first time, demonstrated that implant surface roughness can increase the amount of the translocated bone particles and thereby also have a beneficial effect on the osteogenic response of these bone particles. It is hypothesized that these bone fragments behave like miniature auto-grafts and thereby play a significant role to enhance peri-implant osteogenesis. Optimization of surface topography should be evaluated to take advantage of this additional effect of surface roughness.
