Abstract
An implant material for hard tissue comprising a porous matrix of a mass of biologically-compatible polymeric particles, the particles bonded together to form a unitary prosthetic implant, the prosthetic implant having interstices between the bonded particles forming pores into which bone tissue can grow and having a quantity of calcium hydroxide distributed in the pores of the matrix. Also disclosed is a packing material for forming in vivo prosthetic implants for hard tissue, the packing material comprising a mass of disjoint polymeric particles having an inner core and an outer coating and a quantity of calcium hydroxide distributed in the mass of polymeric particles effective to induce hard tissue growth.
