Patent ID: 7993136

Claim:
A method for producing a physical dental arch model having at least two physical tooth models, comprising: digitally represented positions and orientations of a first physical tooth model and a second physical tooth model in a first digital dental arch model; detecting an interference between the first physical tooth model and the second physical tooth model in the first digital dental arch model; modifying the positions and orientations of the first physical tooth model and the second physical tooth model to produce a second digital dental arch model based on the detected interference between the first physical tooth model and the second physical tooth model; selecting an adjusted configuration of a first feature to be affixed to a bottom portion of the first physical tooth model and a second feature to be affixed to a bottom portion of the second physical tooth model so as to avoid the detected interference; and outputting data for fabricating the physical dental arch model comprising the first physical tooth model and the second physical tooth model in accordance with the modified positions and orientations of the first physical tooth model and/or the second physical tooth model.
