Imaging data from 5 patients with Pruzansky-Kaban type II (IIa: 4; IIb: 1) mandibular deformities were used to print 3D models for simulated mandibular distraction osteogenesis. In the experimental group, a robot-assisted surgical navigation system was used to perform the surgery under robotic guidance following registration, according to the preoperative design. Conventional surgery was performed in the control group, in which the operation was based on intraoperative estimations of the preoperative design by experienced surgeons. The accuracies of the osteotomy and distractor placement were assessed based on distance and angular error. Osteotomy accuracy was higher in the experimental group than in the control group, and the distance error (\n                    <jats:italic toggle=\"yes\">t<\/jats:italic>\n                    =9.311,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt;0.001) and angular error (\n                    <jats:italic toggle=\"yes\">t<\/jats:italic>\n                    =5.385,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    =0.001) were significantly reduced.
