Surface topography

The "gold standard" for osseointegration

Many consider the sandblasted, thermal acid-etched microrough surface to be the “gold standard” for implant surface modification.1, 2, 3, 4, 5, 6, 7

The advantage for implants that feature a microrough surface is that they establish excellent functional and structural connections between the bone and the implant surface, leading to higher intrinsic implant stability.8

Specifically, the microrough surface enhances the interlocking of the implant surface with bone and has been shown to promote the differentiation of osteogenic cells in-vitro.9
