US 12,465,458 B2 · Orthodontic treatment and associated devices, systems, and methods

Abstract

Devices, systems, and methods for orthodontic treatment planning and treatment are disclosed herein. Various embodiments of the present technology are directed to a method of obtaining data characterizing movements of a patient's teeth from original positions to desired, final positions. In some embodiments, the method can include identifying one or more components of the movements, evaluating the movements, and/or modifying the movements. A method of the present technology can comprise obtaining an orthodontic treatment plan, which can include one or more suggested interventions to accomplish the tooth movements, a design of such intervention(s), and/or other useful information regarding the orthodontic treatment. In some embodiments, a method of the present technology comprises evaluating an orthodontic treatment during and/or after implementation of the treatment and, based on the evaluation, obtaining another orthodontic treatment plan and movement data characterizing movements of a patient's teeth from their current positions to desired, final positions.

Dependent claims

A method for manufacturing a shape forming fixture for setting a shape of an orthodontic appliance, the orthodontic appliance being configured to be secured to a plurality of brackets on a patient's teeth, the method comprising:

obtaining a treatment planning digital model characterizing the patient's teeth and the brackets on the patient's teeth in planned positions;
obtaining a current tooth arrangement digital model characterizing the patient's teeth and the brackets on the patient's teeth in actual positions after the brackets have been bonded to the patient's teeth;
for each bracket, determining a difference between a respective actual position of the bracket and a respective planned position of the bracket;
based on the determined difference, creating a shape forming fixture digital model, the shape forming fixture digital model comprising a plurality of securing portions positioned relative to one another to reflect the actual positions of the brackets;
and
forming a physical shape forming fixture based on the shape forming fixture digital model.

A method for manufacturing a shape forming fixture for setting a shape of an orthodontic appliance, the orthodontic appliance comprising a plurality of attachment portions configured to be secured to a plurality of brackets on a patient's teeth, the method comprising:

obtaining a final tooth arrangement (FTA) digital model characterizing the patient's teeth in a final arrangement with each of the brackets located at an intended position relative to a corresponding one of the patient's teeth;
creating a shape forming fixture digital model characterizing a shape forming fixture for setting a shape of the orthodontic appliance based on the FTA digital model, the shape forming fixture comprising securing portions configured to retain the attachment portions of the appliance at the intended positions of the brackets with the patient's teeth in the final arrangement;
obtaining an actual tooth arrangement (ATA) digital model characterizing the patient's teeth in an actual arrangement with each of the brackets located at an actual position relative to the corresponding one of the patient's teeth;
for each bracket, determining a difference between a respective actual position of the bracket and a recti ve planned position of the bracket;
modifying the securing portions of the shape forming fixture digital model based on the determined difference so that the securing portions are configured to maintain the attachment portions of the appliance at the actual positions of the brackets with the patient's teeth in the final arrangement;
and
forming a physical shape forming fixture based on the shape forming fixture digital model with the modified securing portions.
