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 ceramic fibers for use in the reinforcement of biodegradable polymeric fracture-fixation plates. To meet this goal, we have examined the spinnability and processibility of beta-tricalcium phosphate (whitlockite) and phosphate-free calcium aluminate. In studies conducted during the previous 2 years, composites fabricated from poly(DL-lactide)(DL-PLA) and commercially available, nonbiodegradable ceramic fibers were shown to provide sufficient strength and rigidity for use in the repair of mandibular fractures in dogs. Our work during the current renewal period was therefore been directed toward obtaining biodegradable ceramic fibers with mechanical properties sufficient for the fabrication of a totally biodegradable fracture-fixation appliance.
