An engineered regenerative biostructure (erb) for implantation into a human body as a bone substitute, which includes an internal microstructure, mesostructure and/or macrostructure to provide improved bone in-growth, and methods for making the erb. Under one aspect of the invention, the biostructure has resorbable and nonresorbable regions. Under another aspect of the invention, the biostructure is constructed of hydroxyapatite, tricalcium phosphate and/or demineralized bone. Under yet another aspect of the invention, the porous biostructure is partially or fully infused with a resorbable, nonresorbable or dissolvable material.

La présente invention concerne une biostructure de régénération technique destinée à être implantée dans une anatomie humaine comme substitut osseux, qui comprend une microstructure interne, une mésostructure et/ou une macrostructure permettant d'améliorer l'os en croissance ainsi que des techniques de fabrication de biostructure de régénération technique. Dans un aspect de cette invention, la biostructure possède des régions résorbables et des régions non résorbables. Dans un autre aspect de cette invention, la biostructure est constituée d'hydroxyapatite, de phosphate de tricalcium et/ou d'os déminéralisé. Enfin, dans un autre aspect de cette invention, la biostructure poreuse est partiellement ou complètement infusée avec un matériau résorbable, non résorbable ou soluble.
