The Application of Lag Screws and Digital Positioning Guide in Treating Sagittal Split Fracture of the Mandible.

ABSTRACT

Sagittal mandibular fractures are challenging to manage using traditional open reduction and internal fixation techniques due to the difficulty in manually reducing mandibular fragments and performing osteosynthesis on the lingual side. In addition, there is a risk of damaging dental roots with screws during fixation. In this case, the authors employed the lag screw technique combined with digitally guided surgery to effectively perform osteosynthesis on the fragments and avoid iatrogenic tooth and nerve injury.
