Abstract

Background: A variety of plating techniques are employed by microsurgeons to provide rigid fixation for vascularized bone constructs of the mandible. The aim of this study was to biomechanically compare three commonly utilized plating techniques for rigid fixation of fibula bone flaps in reconstructing lateral segmental mandibular defects. Materials and Methods: Polyurethane mandibles with 3-cm segmental defects were reconstructed using polyurethane fibula models. Three fixation techniques were compared (n=5 models per group): Group 1 used two 2.0-mm miniplates at each osteotomy site, Group 2 used a single 2.3-mm plate, and Group 3 used a single 2.7-mm plate. Biomechanical testing of maximum force and displacement at failure for each plating technique was assessed and statistical comparison performed. Results: The average displacement for Group 1 was 14.08±1.42 mm, Group 2 was 5.79±0.89 mm, and Group 3 was 6.03±1.59 mm. Group 1 had significantly greater (P
