Condyle fractures are the most common type of mandibular fracture. This study aims to evaluate the biomechanical performance of four proposed designs and ensure the optimum plate design. Four models were constructed using CAD software (Plates A, B, C, and D). A normal chewing force (100 N) was applied to the first molar location of the non-fractured site. Stresses in plates and reaction forces at the left and right mandibular necks were evaluated using finite element method. Results showed that the lowest peak von Mises stress was in plate D (217 MPa), while the highest stress was with plate A (351 MPa), followed by plate C (250 MPa), then plate B (287 MPa). Higher reaction forces were on the left side non-fracture side. Plate B showed the highest reaction force in the fracture side (33 N), while the lowest value was with plate A, followed by plate C and D (20 N). For the mandibular movement, plate B showed less displacement. It was concluded that among the four designs, plate D demonstrated lower stress distribution and lowest micromotion at the fracture gap compared to the other plates.
