Mandibular fractures with sagittal splitting and splaying of both the near and far cortices pose a challenge in their fixation as screws may push the far cortex during screw tightening, resulting in more widening. Screw lagging inside the lower mandibular plate technique may help approximation of the near and far cortices during screw tightening, and this was applied for 4 cases with mandibular fractures. The splaying improved using this technique. Using the screw lagging inside the plate technique may be a safe technique used in mandibular fractures that have cortical splaying.
