Abstract: Methods and systems for determining a dental treatment difficulty in digital treatment planning. The methods may include calculating tooth position changes from an initial dental model to a target dental model in a mouth quadrant of a patient's dentition. The changes in position may be determined by projecting distances between initial positions and subsequent positions of teeth onto an arch line of the initial dental model. A treatment difficulty of anterior-posterior (A-P) correction may be determined for the mouth quadrant based on an average change in position, wherein a greater average change in position is associated with a higher treatment difficulty of A-P correction. The digital treatment plan may be adjusted so that a provider skill level meets or exceeds the treatment difficulty of A-P correction.

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.
