Abstract
A method of planning an orthodontic treatment for a patient may include receiving a digital representation of the patient's dentition in an initial arrangement, determining a first geometry for an upper shell of an orthodontic appliance. The first geometry may include a first plurality of tooth-receiving cavities shaped to receive an upper jaw of the patient's dentition and an upper cutout disposed along an upper gingival edge of the upper shell. The method may also include determining a location of an upper elastic band receiving member. The location of the upper elastic band receiving member may correspond to a position of the upper cutout. The location of the upper elastic band receiving member may be determined so as to generate a tooth repositioning force to facilitate repositioning of the patient's dentition when an elastic band is secured to the upper elastic band receiving member.
