Osseoincorporation
Osseoincorporation refers to the healing potential of bone onto an implant surface and into an implant structure. Three-dimensional, porous implantable materials used in the orthopedic and dental implant industries offer the potential for ingrowth as well as ongrowth〔Unger, AS. "Evaluation of a porous tantalum uncemented actetabular cup in revision total hip arthoplasty. Clinical and radiological results of 60 hips". J Arthroplasty, 2005, p 1002-1009〕〔Cohen R. "A porous tantalum trabedcular metal: basic science". Am J Orthrop, 2002, p. 216-217〕〔Bobyn JD. "UHMWPE: the good, bad, & ugly. Fixation and bearing surfaces for the next millennium". Orthop, 1999, p. 810-812〕 or osseoincorporation.

Conventional textured or coated implant surfaces are designed to achieve bone-to-implant contact, which is called ''ongrowth''.〔Branemark PI. "Introduction to osseointegration". In Branemark PI, Zarb GA, and Albrektsson T. eds.: Tissue-Integrated Prosthese. Osseointegration in Clinical Dentistry. Chicago, IL: Quintessence Publishing Co, Inc.: 1985, p. 11-76〕 Per-Ingvar Brånemark defined this ongrowth phenomenon, osseointegration, as "the direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant."〔Branemark PI. "Introduction to osseointegration". In Branemark PI, Zarb GA, and Albrektsson T. eds.: Tissue-Integrated Prosthese. Osseointegration in Clinical Dentistry. Chicago, IL: Quintessence Publishing Co, Inc.: 1985, p. 11-76〕 In the case of dental implants, they osseointegrate.〔Osseointegration Study, Journal of Oral Implantology, 2001—Burton E. Balkin et al.〕 Porous implantable materials are designed for bone to grow not only onto the material but also into its pores, and in some cases interconnecting within the material’s structure, in a process called ''osseoincorporation''.〔Unger, AS. "Evaluation of a porous tantalum uncemented actetabular cup in revision total hip arthoplasty. Clinical and radiological results of 60 hips". J Arthroplasty, 2005, p 1002-1009〕〔Cohen R. "A porous tantalum trabedcular metal: basic science". Am J Orthrop, 2002, p. 216-217〕〔Bobyn JD. "UHMWPE: the good, bad, & ugly. Fixation and bearing surfaces for the next millennium". Orthop, 1999, p. 810-812〕〔Tsao AK. "Biomechanical and clinical evaluations of a porous tantaluym implant for the treatment of early-stage osteonecrosis". J Bone Joint Surg, 2005, p.22-27〕〔Bobyn JD. "Clinical validation of a structural porous tantalum biomaterial for adult reconstruction". J Bone Joint Surg, 2004, p. 123-129〕
