Automatic placement of precision cuts
First Claim
1. A computer-implemented method of designing a patient removable orthodontic tooth positioning appliance, comprising:
- receiving a digital representation of a patient'"'"'s tooth;
placing a digital representation of an elastic band receiving member on the tooth; and
generating a cutout line extending between a first point on a gingival line of the tooth and a second point on the gingival line of the tooth, the cutout line defining a gingival-facing surface of the patient removable orthodontic tooth positioning appliance.

Abstract
An orthodontic positioning device and methods for making an orthodontic positioning device including a first patient removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient'"'"'s teeth provided in one of an upper jaw and a lower jaw. The first appliance includes a hook configured to receive an orthodontic elastic band. The orthodontic positioning device also includes a second patient removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient'"'"'s teeth provided in the other of the upper jaw and the lower jaw. The second appliance includes a cutout operable to expose an orthodontic elastic band receiving member.
