abstract = "Background: Several studies proved that anodic oxidation improves
osseointegration. This study aimed to optimize osseointegration
through anodization in dental implants, obtaining anatase phase
and controlled nanotopography. Methods: The division of the groups
with 60 titanium implants was: control (CG); sandblasted (SG);
anodized (AG): anodized pulsed current (duty cycle 30\%, 30 V,
0.2 A and 1000 Hz). Before surgery, surface characterization was
performed using Atomic Force Microscopy (AFM), Scanning Electron
Microscopy (SEM), X-ray Dispersive Energy Spectroscopy (EDS) and
Raman Spectroscopy. For in vivo tests, 10 New Zealand white
rabbits received an implant from each group. The sacrifice period
was 2 and 6 weeks (n = 5) and the specimens were subjected to
computed microtomography (mu CT) and reverse torque test. Results:
AFM and SEM demonstrated a particular nanotopography on the
surface in AG; the anatase phase was proved by Raman spectroscopy.
In the mu CT and in the reverse torque test, the AG group
presented better results than the other groups. Conclusion: The
chemical composition and structure of the TiO2 film were
positively affected by the anodizing technique, intensifying the
biological characteristics in osseointegration.",
