The aim was to evaluate bone-implant contact (BIC) of implants from different brands and different surface treatments. 24 implants were divided into four groups: Group IO Intraoss implants with doubly acid-etched surface, NEO group Neodent implants with sandblasted and acid-etched surface, NB group Nobel Biocare implants with anodized surface and TF group TitaniumFix implants with sandblasted and etched surface. Six adult male New Zealand rabbits received two implants in each tibia. After 45 days of implant placement all animals were sacrificed. The bone blocks removed were analyzed histomorphometrically for quantification of the bone-implant contact area. Qualitative analysis was performed on the topographical aspects of implant surface from groups IO, NEO, NB and TF through using scanning electron microscopy (SEM). The BIC percentage for groups IO, NEO, NB and TF were 53.8 ± 11.2% 59.5 ± 14.3% 61.2 ± 2.9% and 42.8 ± 2.9%, respectively. Qualitative analysis of SEM images showed that the implant surfaces from the four groups had different topographical features, which conformed to their respective surface treatment methods. NB group showed a higher percentage of BIC area, followed by NEO, IO and TF, respectively. Qualitative analysis of topographic morphology by SEM showed characteristics compatible with increased surface roughnesst.
