This study proposes a mandibular fixation technique based on mortise-and-tenon construction. Mandibular defect models with varying interlocking angles were established using the fibula and iliac as grafting materials, and comparative analyses of static stress distribution, displacement control, and fatigue life were conducted. Optimal performance was achieved with a fibular tenon width of 0.8 cm, a length of 1 cm, and an angle of 75°. Fatigue analyses indicated that the system satisfied clinical requirements. The proposed method shows potential for clinical application in mandibular reconstruction.
