To begin with, we applied an additive manufacturing (AM) concept to produce an acrylonitrile butadiene styrene (ABS) three-dimensional (3D) life-size surgical model by using her DICOM computed tomography (CT) data (Figure 1).
Fracture reduction performed following angle mandible osteotomy and then waxing-up to allow adaptation of the reconstruction plate. Note that there is loss of left posterior facial height secondary to condylar neck fracture.

Next, fracture reduction and correction of occlusion were carried out, followed by waxing-up of the multiple defect areas to allow good bending and adaptation of the reconstruction plate (Figure 2).
Intraoperative condylar positioning device on right maxilla. This procedure was completed bilaterally prior to the surgery on the mandible in stabilizing the proximal segments bilaterally.

This was the first step undertaken to prevent any unnecessary change in the condylar position before carrying out further surgical procedures (Figure 3).
Postoperative panoramic showing good fracture reduction and occlusion achieved.

Postoperative follow-up and orthopantomogram showed good healing with restoration of her preinjury states of occlusion (Figure 4).
