Abstract : The U. S. Army Institute of Dental Research was supplied with fabricated devices of biodegradable polyesters for use in evaluation as materials for implant devices. High purity monomers, glycolide and d,l- lactide, were prepared, polymerized, and copolymerized. The polymers and copolymers were evaluated and found to be of high purity with excellent physical properties, such as flexural strengths were 10,000 to 20,000 psi. The polymers were fabricated into approximately 6 kg of plates, rods, and pellets, and sheets for use by USAIDR in clinical studies as indicated by the report title. (Author, modified-PL)
