Patent number: 11986369Abstract: 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.Type: GrantFiled: December 14, 2020Date of Patent: May 21, 2024Assignee: Align Technology, Inc.Inventors: Artem Borovinskih, Roman A.
