Injuries to the maxillofacial area have been on the increase primarily as a result of increased numbers of automobile accidents. A substantial number of maxillofacial injuries also occur in industry. Of all the injuries, fractures of the facial skeleton produced the greatest morbidity.
Present methods of treating jaw fractures have satisfactorily restored cosmetic and functional deformities resulting from these injuries. However, prolonged fixation, the necessity of hairline reduction, and the multitude of complications which are associated with these fractures have prompted a review of our present treatment methods and a possible new approach to therapy.
Plastic polymers,2 such as polyvinyl sponge,4,11 have been successfully used to bridge osseous defects in the maxillofacial region. Even plaster of Paris had been used in bone defects with satisfactory results.9 Ballen1 has used methyl methacrylate in orbital defects but stated that its employment in stress situations has not been evaluated.
