Abstract

Implants with surface chemical or biomechanical qualities that should encourage bone formation have been developed over the last 30 years. Few systematic investigations have been conducted on surface topography despite the widespread recognition that it is a significant factor influencing bone-implant contact. Four white New Zealand mature rabbits were used in the present investigation. Each rabbit received 2 implants, specially made with 2 surfaces on it (one sandblasted and acid etched and one machined) into each tibia. A total of 16 implants were inserted. All animals were killed 21 days after implant placement. Osteoblast in contact with the implant surface was statistically evaluated. The sandblasted and acid-etched surfaces showed a greater osteoblast contact than the machined, which was statistically significant. The sandblasted and acid-etched surface improves osteoblast adhesion on the implant surface.
