Surface Coatings of Implants
Ø Titanium plasma spray
Ø Abrasions using TiO2 blasting
Ø Blasting & etching using alumina & sulfuric or hydrochloric acid
Ø Anodizing
Ø Cold working (dimpling)
Ø Sintering
Ø Magnetron sputtering using calcium sulfate apatites
Ø Bead compaction methods
Advantages of Surface Coatings
Surface Design of Implants
Surface Roughness of Implants
Speeds up bone apposition Any grooves in the surface guide cell migration along their direction thereby allowing bone to adhere to even the tiniest irregularity Better interlock & biomechanical response Accentuates ability of Ti to integrate without inflammation.
