A bone fixation implant is provided that includes a bone fixation plate and a plurality of fasteners. The bone fixation plate corresponds generally to stress lines (A, B, C, D) imparted onto the mandible during anatomical function of the mandible. Thus, the bone fixation plate includes a primary leg (54) and an auxiliary leg (56) extending obliquely out from the primary leg. The primary leg generally corresponds in shape to a posterior border (25) of a mandible, and the auxiliary leg generally corresponds in shape to a sigmoid notch (31) of a mandible.
