Methods and systems for IPR planning. One method includes identifying an overlap between a first tooth and a second tooth in a patient's dentition at a target position of a treatment plan; identifying first and second ridge endpoint reference lines on each of the first tooth and the second tooth; calculating a distance difference between the first and second ridge endpoint reference lines; determining that the distance difference is outside a threshold difference; revising the treatment plan by adding one or more stages to the treatment plan where the distance difference between the first and second ridge endpoint reference lines is within the threshold difference; and prescribing IPR on one or both of the first and second teeth at the one or more additional stages of the treatment plan.

Methods and systems for interproximal reduction planning

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.
