Particular aspects provide bioresorbable and biocompatible compositions for bioengineering, restoring or regenerating tissue or bone, comprising a three-dimensional porous or non-porous scaffold material comprising a calcium phosphate-based ceramic having at least one dopant therein selected from metal ion or ion dopants and metal oxide dopants, wherein the composition is sufficiently biocompatible to provide for a cell or tissue scaffold, and resorbable at a controlled resorption rate for controlled strength loss, depending on dopant composition, under body, body fluid or simulated body fluid conditions. Preferably, the at least one dopant is selected from the group consisting of Zn, Mg, Si, Na, K, Sr, Cu, Fe/Fe, Ag, Ti, CO, F, MgO, ZnO, NaF, KF, FeO/FeO, SrO, CuO, SiO, TiO, AgO and CaCO, present in an amount between 0 and about 10 w %, from about 0.5 to about 5 w %, or from about 1 to about 3 w %, and methods of using same.
