Abstract
Titanium surface is an important factor in achieving osseointegration during the early wound healing of dental implants in alveolar bone. The purpose of this study was to evaluate sandblasted-etched surface implants to investigate the osseointegration. In the present study, we used two different types of sandblasted-etched surface implants, an SLA™ surface and a Nanoblast Plus™ surface. Roughness and chemical composition were evaluated by a white light interferometer microscope and X-ray photoelectron spectroscopy, respectively. The SLA™ surface exhibited the higher values (Ra 3.05 μm) of rugosity compared to the Nanoblast Plus™ surface (Ra 1.78 μm). Both types of implants were inserted in the femoral condyles of ten New Zealand white rabbits. After 12 weeks, histological and histomorphometric analysis was performed. All the implants were osseointegrated and no signs of infection were observed. Histomorphometric analysis revealed that the bone–implant contact % (BIC) ratio was similar around the SLA™ implants (63.74 ± 13.61) than around the Nanoblast Plus™ implants (62.83 ± 9.91). Both implant surfaces demonstrated a favorable bone response, confirming the relevance of the sandblasted-etched surface on implant osseointegration.

Summary
Titanium surface is an important factor in achieving osseointegration during the early wound healing of dental implants in alveolar bone. Histomorphometric analysis revealed that the bone–implant contact % (BIC) ratio was similar around the SLATM implants (63.74 ± 13.61) than around the Nanoblast PlusTM implants (62.83 ± 9.91) Both implant surfaces demonstrated a favorable bone response, confirming the relevance of the sandblasted-etched surface on implant osseointegration. Introduction with regard to jurisdictional claims in Currently, dental implants are considered as a successful alternative to replace missing teeth with a predictable prognosis and are widely used in oral implantology for prosthodontic restorations [1,2,3,4] Experimental studies in this field demonstrated that titanium is an excellent material due to its characteristics of biocompatibility, stability and resistance [5,6,7]
