The titanium surfaces with micro-roughness have been studied to substitute machined titanium, with the focus on enhancing the bone apposition onto the implant. In this study we have followed a biomimetic strategy where human SAOS-2 osteoblasts proliferated and built their extracellular matrix on a sandblasted titanium surface modified with plastic deformation. In comparison with sandblasted titanium surface, the plastic deformation increased the cell proliferation and the surface coating with bone matrix. The superficially modified biomaterial could be used, in clinical applications, as an implant for bone repair.

Abstract
The titanium surfaces with micro-roughness have been studied to substitute machined titanium, with the focus on enhancing the bone apposition onto the implant. In this study we have followed a biomimetic strategy where human SAOS-2 osteoblasts proliferated and built their extracellular matrix on a sandblasted titanium surface modified with plastic deformation. In comparison with sandblasted titanium surface, the plastic deformation increased the cell proliferation and the surface coating with bone matrix. The superficially modified biomaterial could be used, in clinical applications, as an implant for bone repair.File in questo prodotto:
