ABSTRACT

Current literature reports that surface acid-etching can improve osteointegration. The aim of the present pilot investigation was to evaluate the bone-implant contact of sandblasted/acid-etched surface implants through micro-CT. Two white New Zealand mature rabbits were treated in the present study, while each rabbit received 2 implants. A total of 4 implants were positioned. The animals were euthanised at 30 days from the implant positioning. The micro-CT sandblasted/acid-etched showed a mature bone appearing in close contact with sandblasted/acid-etched surface of the implant. The sandblasted/acid-etched surface appears to improve bone-implant contact at a later stage of healing.
