virtual planning will be done using the manual virtual reduction method and . Design of the reduction guide will be done in accordance with the virtual plan. The surgical reduction will be done with the aid of the guide.

virtual planning will be done using the mirror image technique. Design of the reduction guide will be done in accordance with the virtual plan. The surgical reduction will be done with the aid of the guide.

Mandibular fracture treatment by 3d printed guide where virtual planning will be done using the manual reduction technique.

Evaluation of accuracy of surgical guide will be done using slicer and blender software with the aid of the preoperative and postoperative CT.

Preoperative planning will be merged with the new CT data to identify the accuracy of reduction.

Landmark-Based Positional Analysis was used to quantify positional accuracy of the reduced mandibular segment. Bilateral mandibular landmarks were selected to represent the spatial position of the fractured and adjacent segments. The selected landmarks included condylion (Co), gonion (Go), and mental foramen (MF), which are distributed across the mandibular ramus, angle, and body regions. linear distances to the three reference planes were recorded in millimeters. To provide a comprehensive three-dimensional representation of positional discrepancy, an asymmetry index (AI) was calculated for each bilateral landmark.

Assessment of occlusion will be done By checking the maximal intercuspal position (centric occlusion) to ensure proper occlusal relationship including molar relation, canine relation and midline centralization.

The percentage of patients suffering from occlusal disturbances will be recorded.
