Perpendicular positioned screw to the bevel of the fracture

Lag screw insertion

Depending on the fracture plane orientation, lag screw alignment will vary. For sagittal fractures through the anterior mandible, lag screws placed through the outer cortices from one side to the other within the substance of the mandible (buccal cortex to buccal cortex) provide extremely stable fixation.

Note that the screws and the resultant compression are directed perpendicular to the bevel of the fracture.
