Multi-scale surface modification of Ti for orthopedic implant application

摘要

The multi-scaled surface roughness on Ti has been successfully created via combined SLA and SPE process. The superimposed nanoscale roughness onto the micro-roughened SLA was found to significantly improve cell attachment and differentiation with in vivo bone regeneration. The multi-scale roughened surface by the SLA-SPE process shows great potential for surface treatment of various orthopaedic implants.
