Purpose:
To evaluate the clinical results of cortical (lag) screws in internal fixation of mental fractures.
Methods:
12 patients with single linear mental fracture underwent internal fixation using cortical screws. The patients were followed up for 6 to 9 months after fixation.
Results:
Of 12 cases, 1 cortical screw was used in 10 cases, and 2 cortical screws were used in 2 cases. The wound healed primarily postoperatively. The patients had normal occlusion and mouth opening.
Conclusion:
Fixation of mental fracture using cortical screw can achieve good stability and appropriate compression. The technique is simple and easily performed, which avoids the bending of the reconstruction plate to adapt to the complex configuration of the mandible, reduce the surgical time, and promote the healing process by producing stress in the fracture lines.
