The mechanical characteristics of the mandible after bilateral sagittal split osteotomy through the use of 2 different plates to stabilize the osteotomy were compared by using three-dimensional finite element method. Three dimensional models were developed based on the geometry reconstructed from computed tomography. Straight(I-type) and L-type plates with 4 cortical screws were used to stabilize the osteotomy. A 41.6N univertical compressive load was applied above left first molar in downward direction. To evaluate the mechanical characteristics of these 2 plates, following two items were compared: 1) the resulting deflections at the central incisor of left side, 2) the mechanical stresses developed at the 4 screws of the stabilizing plates. The smaller deflection was found at the central incisor of L-type plate and the plate suggested higher mechanical stability. The lower mechanical stresses were acting on the L-type plate, whereas I-type plate is associated with higher values.
