1. Method for predicting and designing the porosity of a biocompatible polymer-ceramic composite material, characterized by the fact that it includes the following phases:
(a′) producing a suspension of a bioceramic material in distilled water;
(b′) starting from identical volumetric quantities of initial suspension, obtaining from the suspension a series of compacts of the selected bioceramic material containing different quantities of water;
(c′) mixing each of said compacts obtained with an identical quantity of a polymeric material and/or a liquid monomer in order to obtain a porous geometric solid of pre-defined dimensions;
(d′) for each compact, calculating the porosity of the solid by obtained from it; and
(e′) correlating said porosity with the compact's residual content in water.
