Treatment progress tracking and recalibration
First Claim
1. A method for identifying and correcting deviations of a patient'"'"'s teeth from an orthodontic treatment plan, the method comprising:
- scanning a patient'"'"'s teeth with a scanner to form an unsegmented three-dimensional (3D) model of a current tooth arrangement of the patient;
comparing, using one or more processors, a previously segmented 3D digital model of a target tooth arrangement specified by the orthodontic treatment plan to the unsegmented 3D digital model of a current tooth arrangement of the patient;
identifying, using one or more processors, a discrepancy between the current tooth arrangement and the target tooth arrangement based on the comparing; and
generating, using one or more processors, a modified orthodontic treatment plan in response to the identified discrepancy.

Abstract
The present invention relates to systems and methods of developing and tracking delivery and patient progression through an orthodontic treatment plan. One method includes identifying deviations from an orthodontic treatment plan, including receiving a digital representation of an actual arrangement of a patient'"'"'s teeth after an orthodontic treatment plan has begun for the patient and prior to completion of the orthodontic treatment plan. The method further includes comparing the actual arrangement to a pre-determined planned arrangement to determine if the actual arrangement substantially deviates from the planned arrangement, the comparing comprising matching teeth from a previously segmented model to a surface of an unsegmented representation of the actual arrangement; and calculating one or more positional differences between the actual and planned arrangements of at least some of the corresponding teeth.

8. A system for identifying and correcting deviations of a patient'"'"'s teeth from an orthodontic treatment plan, the system comprising:
-
one or more processors; and memory, including instructions executable by the one or more processors to cause the system to at least; scan a patient'"'"'s teeth with a scanner to form an unsegmented three-dimensional (3D) model of a current tooth arrangement of the patient; compare a previously segmented 3D digital model of a target tooth arrangement specified by the orthodontic treatment plan to the unsegmented 3D digital model of a current tooth arrangement of the patient, identify a discrepancy between the current tooth arrangement and the target tooth arrangement based on the comparing, and generate a modified orthodontic treatment plan in response to the identified discrepancy. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. One or more non-transitory computer-readable storage media having stored thereon executable instructions that, when executed by one or more processors of a computer system for identifying and correcting deviations of a patient'"'"'s teeth from an orthodontic treatment plan, cause the computer system to at least:
-
scan a patient'"'"'s teeth with a scanner to form an unsegmented three-dimensional (3D) model of a current tooth arrangement of the patient; compare a previously segmented 3D digital model of a target tooth arrangement specified by the orthodontic treatment plan to the unsegmented 3D digital model of a current tooth arrangement of the patient, identify a discrepancy between the current tooth arrangement and the target tooth arrangement based on the comparing, and generate a modified orthodontic treatment plan in response to the identified discrepancy. - View Dependent Claims (17, 18, 19)
