1. A computer-implemented method for generating a modified patient image for an orthodontic treatment plan, the computer-implemented method comprising, by one or more processors:
accessing a 3D model comprising a virtual representation of a patient's dentition at a treatment stage of an orthodontic treatment plan;
obtaining an image of the patient's face and at least a portion of the patient's dentition;
projecting the obtained image into a 3D space to create a projection of the patient's face and the at least the portion of the patient's dentition;
generating a modified image of the patient representing the patient in the treatment stage of the orthodontic treatment plan, wherein the modified image is formed by combining the patient's dentition of the accessed 3D model with the patient's face of the projection; and
sending instructions to display the modified image of the patient on an output device.
