Accuracy of a CAD/CAM surgical template for mandibular distraction: a preliminary study

We have assessed the accuracy and clinical validation of virtual planning using a surgical template in 16 patients with hemifacial microsomia being treated by mandibular distraction osteogenesis. Virtual planning and simulation were first done on three-dimensional models. Distraction was simulated on the virtual model and the new morphology of the mandible was previewed. Both the position and direction of the distractor were calculated to achieve the optimal morphology. The templates were designed based on the virtual planning, and manufactured using a 3-dimensional printing technique. (Source: The British Journal of Oral and Maxillofacial Surgery)
