Abstract:
1. A computing device implemented method for designing a restored smile, the method comprising: receiving scan data of a patient's teeth; developing a digital model of the patient's teeth via the computing device, where the model represents the patient's teeth based upon the scan data; receiving image data of a smile of the patient including at least a frontal image of a patient's lips defining the smile and teeth of the patient that are visible between the lips in the smile data; mapping a number of reference points in the image data of the smile and creating a line that intersects the reference points that defines an inner lip line of the smile; creating a dental treatment plan for the digital model of the patient's teeth to move one or more of the patient's teeth from an initial condition through a number of successive conditions to a final condition, wherein the final condition includes one or more teeth having at least one planned additional restorative tooth structure provided therewith; combining the digital model of the patient's teeth with the image data of the smile of the patient including the inner lip line of the smile; and showing the smile as it would appear in the final condition according to the inner lip line and the digital model in the final condition.
