Abstract: Systems and methods for rapidly and reliably determining an arch width of a patient's dental arch. A three-dimensional (3D) model of a patient's teeth, including a target tooth, can be received. Dental features from the 3D model may be extracted. The dental features may include a point of intersection between an occlusal surface of a tooth and a long axis of the tooth. An arch width between the target tooth and an opposing tooth may be determined based on the extracted dental features.

Abstract: Systems and methods for rapidly and reliably determining an arch with of a patient's dental arch. A patient's dentition may be scanned and/or segmented. Arch width may be determined between points of intersection on the occlusal surface and a long axis of each tooth between one or more of: canine, first bicuspid, first primary molar, second bicuspid, second primary molar, and permanent first molar. Arch widths of different modified versions of the patient's dentition may be dynamically compared the patient's starting dentition, or to each other, and may be dynamically updated as the user modifies or switches between one or more 3D models of the patient's dentition.
