Mandibular fractures mostly occur at the angulus mandibula with a concurrent symphysis or corpus fracture on the opposite side. Misapplication can damage the nerves, adjacent teeth, soft tissues, and result in permanent tooth germs. In children, growth centers can be damaged, and this may result in asymmetry and retardation in growth and development. The aim of this study was to compare the mechanical stabilization after different techniques were used to create the mandibular angle fracture fixation and to create oblique fractures at mandible angles. This study included 32 hemi-mandibles that were divided into 4 groups with 8 units per group. All of the hemi-mandibles were fixated using different techniques; titanium mini plates and screws, resorbable mini plate and screws, and resorbable mini plates and cyanoacrylate bone adhesive only. The fixated mandibles were tested under molar masticatory forces, and their stabilization endurance was assessed. There were no significant differences in titanium mini plaque screw and resorbable plaque screw techniques under 40 N force. Resorbable and titanium plates and screws did not have any advantage over each other in terms of biomechanical behaviors. It is suitable to use adhesives in the reduction of complicated but nonload-bearing areas. The adhesive used in this study can adhere to the bone but should be further evolved for clinical use.
