title: Universal polycarbonate fracture splint and its direct bonding potential.
abstract: A polycarbonate splint has been presented which offers the advantage of the ability of being bonded and/or wired into place. This new type of splint offers several advantages over traditional steel splints. The splint can be bonded and/or wired to the dental arch; the bonding method can be a time-saver. The polycarbonate material is readily malleable and does not possess an intrinsic tension or spring usually found in plastics when they are bent or shaped. The splint is highly esthetic when compared to steel splints. Polycarbonate splints are more economical than steel splints. Molded plastic surfaces are smoother and are more compatible with the oral mucosal than the stamped steel surfaces. Finally, and most importantly, the patient acceptance of polycarbonate splints appears to be very good in comparison with steel splints. The above advantages seem to indicate that the future acceptance of this type of splint for maxillofacial injuries will be good, although, it should be understood that plastic splints are not as strong as steel splints and may occasionally break after several weeks of use. Breakage, however, may not cause the splint to become unusable and usually does not occur until after the 4th week of use, if at all.
