Abstract

A bone replacement and repair material prepared from a biocompatible polyester resin, a liquid linking agent capable of cross-linking the resin and a filler is moldable and formable and cures in vivo. The resulting cured putty also degrades in vivo to provide interstices in the polyester matrix for new tissue growth. The polyester resin can also be used as an implantable matrix containing a pharmaceutical agent therein for sustained release of said pharmaceutical from said matrix in a physiological environment.
