Abstract
Methods for tracking progress of a patient undergoing orthodontic treatment are provided. In some embodiments, a method includes receiving a 3D model of a dental arch. The 3D model can be generated by receiving a plurality of images of the dental arch, at least some of the images including a portion of the dental arch together with a portion of a reference element. A registration can be determined between an image and at least one other image using the portions of the reference element in the respective images to improve registration accuracy. The plurality of images can be stitched together according to the determined registrations to generate the 3D model of the dental arch. The method can further include assessing progress of the orthodontic treatment by comparing the 3D model of the dental arch to a previous 3D model representing an earlier state of the dental arch.
