Abstract: Methods and systems for determining a dental treatment difficulty in digital treatment planning. The methods may include determining changes in position of first and second teeth between initial and target dental models relative to an arch line of the initial dental model of a patient's dentition. The changes in position may be determined by projecting first and second distances between initial and subsequent positions of the teeth onto the arch line. A treatment difficulty of anterior-posterior correction may be determined by comparing a calculated average change in position to one or more threshold changes in position. The digital treatment plan may be adjusted when the average change in position is greater than at least one of the one or more threshold changes in position.

Abstract: Embodiments for determining a dental treatment difficulty are described herein. One method embodiment includes receiving an initial and subsequent position of each of a first tooth and a second tooth and calculating a change in position of each of the first tooth and the second tooth. The method embodiment can also include projecting the changes in position of each of the first tooth and the second tooth onto a reference line and calculating a change in position on the reference line for the first tooth and the second tooth. The method embodiment can further include determining the dental treatment difficulty based on the changes in position on the reference line.
