Influence of surface roughness of dental zirconia implants on their mechanical stability, cell behavior and osseointegration

Abstract

AbstractIt is generally accepted that a micrometer scale roughness supports the osseointegration of titanium implants. While abrasive technologies can easily be employed to create a micro-topography on titanium surfaces, the preparation of rough ceramic surfaces is more challenging. Typically, abrasive treatments of yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) surfaces result in rather smooth topographies (R
