In the past, the effectiveness of intraosseous fixation devices in Hydroxyapatite (HA) implanted and bone grafted areas has not been well defined. Previous definitions of the histologic meaning of osteointegration have implied that only through contact with viable calcified osseous matrix or all implant surfaces is an intraosseous fixture fully integrated or attached (1). Such a definition would preclude the use of these implants in previously bone grafted, HA implanted, or otherwise compromised sites. The purpose of this work was to study the surface interface of metallic intraosseous fixtures in HA implanted and xenogeneic bone-implanted mandibular extraction sockets of mature Macaca fascicularis monkeys and Papio anubis baboons.
