1. A method for visualizing a patient dentition orthodontic treatment comprising:
acquiring a surface contour model of patient dentition;
segmenting the surface contour model to identify one or more segmented teeth;
identifying at least one unerupted tooth within the surface contour model, wherein the at least one unerupted tooth is identified using at least one of three-dimensional volume acquisition or panoramic radiography;
accessing shape and size information for the unerupted tooth based, at least in part, on the at least one of the three-dimensional volume acquisition or the panoramic radiography;
identifying a substitute model tooth based at least in part on the shape and size information for the unerupted tooth, wherein the substitute model tooth reflects a replacement permanent tooth model; and
generating a virtual setup of the patient dentition, wherein a location corresponding to the at least one unerupted tooth is replaced by the replacement permanent tooth model.
