    Abstract: The present disclosure includes computing device related, systems, and methods for IPR planning as described herein. One method includes identifying a first tooth and a second tooth in a digital dental model with an overlap in a target final position in a treatment plan and identifying a reference line on each of the first tooth and the second tooth; revising the treatment plan wherein a position of each of the first tooth and the second tooth is determined in which the reference line of each of the first tooth and the second tooth are aligned and the first tooth and second tooth are not overlapping; and prescribing IPR based on the determined position of each of the first tooth and the second tooth.

    Abstract: The present disclosure provides method, systems, and devices for expanding arch of teeth. A device for expanding an arch of teeth of a patient can include a removable shell formed of a first material having a number of cavities formed therein. The number of cavities are shaped to receive teeth of a patient. A device for expanding an arch of teeth of a patient can include an arch element extending from the removable shell in a lingual direction and across an arch width of the removable shell. The arch element can be formed of the first material and a second material that is a different material than the first material, can be designed to expand an arch of the teeth of the patient, and can have a width specific to a stage of a treatment plan.
