ORAL SURGERY: Jaw surgery simulation - Dr. Hera Kim-Berman

So currently in orthodontic residency education orthognathic or jaw surgery treatment is taught in a very two-dimensional way. 

Basically we use a two-dimensional film a radiograph and then we trace our outlines of the profile we cut them into sections of the jaws upper jaw lower jaw maybe the chin and then move them around on a tabletop to predict possible movements in a two-dimensional way.
