Surface Analysis of an Original Brånemark Implant and Three Related Clones

Selected surface characteristics of screw-type titanium dental implants from four different manufacturers were evaluated. Considerable differences in surface and near-surface contaminants were demonstrated. The fixture treated with radiofrequency glow discharge (plasma) demonstrated the thinnest titanium oxide layer and the cleanest surface.
