Resumen

Purpose: To compare 3 types of intermaxillary fixation (IMF) and their behavior when subjected to tension forces in 3 study models with a palatine fracture feature. Materials and Methods: An experimental study of 3 identical acrylic models was performed. All had the same palatine fracture pattern on the maxillary midline. All were reduced with different IMF methods (ie, direct interdental wiring, Erich arch bars, and self-tapping screws). Tension forces were applied to the study models to observe the fracture line behavior. Results: IMF with direct interdental wiring did not cause significant separation of the fracture feature in the anterior or posterior sector. IMF with the Erich arch bars caused a 2-mm separation in the anterior sector and 0 mm in the posterior sector. The IMF with self-tapping screws caused a 3-mm separation in the anterior sector and 1 mm in the posterior sector. Conclusions: IMF using self-tapping screws resulted in the greatest separation of the fracture compared with the results with Erich arch bars and direct interdental wiring. IMF with self-tapping screws tended to displace the fracture lines by application of the vector furthest from the center of resistance.
