ABSTRACT:
This invention relates to a method for preparing a porous bone implant containing a calcium-based mineral. The method includes immersing a porous matrix in an acidic solution containing a calcium-based mineral; removing the matrix from the solution; and exposing the matrix to an alkali to neutralize the acidic solution, thereby causing precipitation of the calcium-based mineral to obtain a porous bone implant containing a calcium-based mineral.
