1. A method of generating a dental restoration to restore an anterior tooth of a patient to avoid interference with an opposing dentition, the method comprising: generating an interference surface defining a set of possible locations of an opposing dentition relative to a site of the dental restoration, using a computing device, by: receiving a digital model of the opposing dentition; receiving motion data defining motion of the opposing dentition relative to the site of the dental restoration; and determining locations of the opposing dentition when moved according to the motion data; generating, using the computing device, an incisal guide path based on the interference surface and corresponding to the lingual surface of the dental restoration for the anterior tooth; fabricating an incisal guide path structure based on the incisal guide path; and using the incisal guide path structure to generate the dental restoration.
