Development of Biodegradable Implants for Use in Maxillofacial Surgery.

Abstract

The objective of the project is to develop high-strength, bioabsorbable materials useful in the treatment and management of maxillofacial injuries. The specific goal for the current contract year has been the attainment of high-strength, high-modulus, biodegradable fibers for use in the reinforcement of biodegradable polymeric fracture-fixation plates. In studies conducted during the previous years of the project, composites fabricated form poly(DL-lactide) (DL-PLA) and commercially available, non-biodegradable ceramic or carbon fibers were shown to provide sufficient strength and rigidity for use in the repair of mandibular fractures in dogs. Our work during this period has been directed toward the examination of biodegradable ceramics and glasses for the production of biodegradable fibers for use in the construction of totally absorbable fixation-plate appliances.
