Resum
The surface modifications of titanium dental implants play important roles in the
enhancement of osseointegration. The objective of the present study was to test two di erent
implant surface treatments on a rabbit model to investigate the osseointegration. The tested surfaces
were: a) acid-etched surface with sandblasting treatment (SA) and b) an oxidized implant surface
(OS). The roughness was measured by an interferometeric microscope with white light and the
residual stress of the surfaces was measured with X-ray residual stress Bragg–Bentano di raction.
Six New Zealand white rabbits were used for the in vivo study. Implants with the two di erent
surfaces (SA and OS) were inserted in the femoral bone. After 12 weeks of implantation, histological
and histomorphometric analyses of the blocks containing the implants and the surrounding bone
were performed. All the implants were correctly implanted and no signs of infection were observed.
SA and OS surfaces were both surrounded by newly formed trabeculae. Histomorphometric analysis
revealed that the bone–implant contact % (BIC) was higher around the SA implants (53.49 8.46)
than around the OS implants (50.94 16.42), although there were no significant statistical di erences
among them. Both implant surfaces (SA and OS) demonstrated a good bone response with significant
amounts of newly formed bone along the implant surface after 12 weeks of implantation. These results
confirmed the importance of the topography and physico–chemical properties of dental implants in
the osseointegration.
