A method of pre-operatively forming a surgical splint configured to receive a patients dentition can include combining a 3-D facial computer model and a 3-D dental computer model. The method includes the step of obtaining a 3-D facial computer model of at least the patients maxilla, mandible, and dentition from a CT scanner and the step of obtaining a 3-D dental computer model of the patients dentition with an optical scanner. The 3-D dental computer model is then combined with the 3-D facial computer model to form a composite virtual model. The composite virtual model can be manipulated into a planned post-operative shape, and a surgical splint can be custom constructed to match the planned post-operative shape. The surgical splint can be configured to receive the patients dentition.
