Development of Repair Materials for Avulsive Combat-Type Maxillofacial Injuries.
Abstract
The progress in the current program to produce a biodegradable material for maxillofacial reconstruction based on poly(propylene fumarate) is essentially on schedule. The various organic components required, liquid and solid poly (propylene fumarate) and solid polylactic acid have been prepared. These have been formulated, along with inorganic fillers, into pastes which have handling properties suitable for maxillofacial reconstruction, similar to modeling clay. These pastes have been crosslinked into solid materials which appear to have sufficient rigidity and strength for the intended application. Leaching studies suggest that the biodegradability of these materials has been preserved after cross-linking and that the se of an inorganic filler which is leached from the composite fairly rapidly will provide channels for bone regeneration.
