Digitization of target dental arch model
WO 2007120920 A3
Methods and apparatus are disclosed for generating digital models of arrangements of a patient's teeth. The methods comprise acquiring a physical model of an arrangement of the patient's teeth, and generating a digital model of the arrangement from the physical model. Arrangements of the patient's teeth that may be digitally modeled by these methods include, but are not limited to, the current arrangement of the patient's teeth in the patient's mouth, a predicted or desired post-treatment arrangement of the patient's teeth, an arrangement of teeth intermediate between the current and predicted or desired post-treatment arrangement, or another arrangement of the patient's teeth that is modified compared to the current arrangement. In some variations, the digital model may be used in the fabrication of dental appliances including but not limited to dental aligners.
