Cranio-maxillary fixation using supra-orbital pins.
This paper compares the forces which external frames, used for cranio-maxillary fixation, can resist. Clinically, several frames using supra-orbital pins have been proven satisfactory. By quantifying the resistance forces, a more objective assessment of their effectiveness is made. The resistance to backward displacement of the maxilla is measured and compared for 3 frames. Two frames are used for comparison of resistance to occlusal forces.
