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