Abstract
A bioresorbable material is incorporated with bioactive agents to form an implant used for treatment against hard tissue or soft tissue defects and diseases. Antibiotics or anti-cancer agents are incorporated to treat hard or soft tissue infections or cancers. Sustained release of the bioactive agents or drug molecules may be achieved after implantation at the targeted sites. The dosage of the active agents or molecules, the microstructure, morphology, and composition of the bioresorbable material allow control of the release profile. The invented implant may be used for drug delivery, chemotherapy, or gene therapy. Various microstructure and the morphologies of the implants are injectable like putty or shaped with multilayers.
