Polyacrylic acid-alumina composites have been developed in this laboratory and were found to be biocompatible and resistant to biodegradation. These composites can be designed to apply a predetermined pressure on the bone interface which was found beneficial for stimulation of new bone formation and increased bone densification at the implant interface. Optimization of the physical and mechanical properties is presented, and a brief summary of the subcutaneous and oral implantation is reported.
