Computer-guided mandibular fracture treatment

Purpose: This study aimed at evaluating the accuracy of computer guided mandibular fracture reduction.

Patients and method: Ten patients were included in this study. A preoperative radiographic assessment cone beam computed tomography (CBCT) scan was performed to all patients. The digital imaging and communications in medicine (DICOM) files of the CBCT were imported by the MIMICS software then a 3D construction and virtual reduction of the fracture segments was performed. A virtual bone borne surgical guide was designed exported by the software as a standard tessellation language STL file. The STL file was imported by a 3D printing machine and a physical guide was constructed. ORIF was done for all patients and the fracture segments were anatomically reduced by the aid of the computer surgical guide. A post operative CBCT was obtained 7 days post operatively.

Results: There was no statistically significant difference between the virtual reduction and the actual reduction.

Conclusion: The usage of the computer based surgical guide was found to be beneficial for the edentulous patients, and partially edentulous patients with insufficient teeth to act as an occlusal guide.
