AI summary

Systems and methods for generating a treatment plan include a system for receiving a first series of three-dimensional (3D) representations of an upper dental arch and a lower dental arch showing a progression of teeth in the upper dental arch and lower dental arch. The system identifies a distance between a tooth from the upper dental arch and corresponding tooth from the lower dental arch and determines a movement of the upper dental arch or the lower dental arch to decrease the distance between the tooth from the upper dental arch and the corresponding tooth from the lower dental arch. The system generates a second 3D representation of the plurality of upper teeth and the plurality of lower teeth based on the determined movement to reflect the minimized distance and a visualization depicting the progression of the teeth in the upper dental arch and the lower dental arch.
