title: Chemical modification of pure titanium surfaces for oral implants.
abstract: A technique that achieves different pure titanium surfaces depending on acid concentration and exposure time is described. It is possible to obtain, with the same chemical treatment, both large pits and small rugosities. This technique may have interesting applications in oral implants.
