A biomechanical model utilizing polystyrene mandibles was devised to evaluate the fixation efficacy of various plating techniques for repair of mandibular angle fractures. A simple angle fracture was created in the mandible models at a standardized location and was repaired using five different plating techniques. Each experimental group consisted of 15 mandibles, with fracture site, plate placement, load application, and fracture displacement measurement standardized to ensure consistency among experimental groups. Measurement of fracture distraction under load application generated a load deformation curve and corresponding slope for each technique. Comparison of load deformation slopes allowed assessment of fixation stability. When applied with a subapical, medially placed monocortical tension band, bicortical compression plating demonstrated the most stable fracture fixation. The data show that biplanar plate placement in both monocortical noncompression and bicortical compression techniques yields a stronger fixation than monoplanar placement.
