System, method and device for correcting malocclusion

Abstract

Methods and systems are provided for manufacturing a patient's malocclusion appliance. The method may include measuring the position of the patient's teeth and receiving the tooth movement constraints. The method may also include generating an initial treatment plan based on the measured tooth position and tooth movement constraints, and measuring the malocclusion of the patient's teeth for one or more types of dental malocclusion. The method may also include generating a plurality of treatment plans from the initial treatment plan based on the measured malocclusion, and generating a model of the appliance for each stage of the treatment plan. The method may also include generating instructions for manufacturing an appliance for each stage of the treatment plan based on the model of the appliance for each stage of the treatment plan.

[0002] This application claims the benefit of US Provisional Application No. 62 / 547,004, filed August 17, 2017, which is incorporated herein by reference. Background technique

[0003] Treatment planning and manufacture of aligners is a linear, back-and-forth process with a delay between providing feedback and revising the treatment plan, and requires expertise to point out which patients have malocclusions to correct. This process is not ideal because it leaves room for error in the treatment planning process. SUMMARY OF THE INVENTION

[0004] A method of manufacturing an orthodontic appliance is disclosed. The method may include measuring the position of the patient's teeth and receiving the tooth movement constraints. The method may also include, for one or more types of dental malocclusion, measuring a first element of the patient's dental malocclusion, and generating a plurality of treatment plans based on the measured tooth positions and toot...

Embodiment Construction

[0043] Figure 1A An exemplary tooth repositioning appliance or aligner 100 is shown that may be worn by a patient to achieve incremental repositioning of a single tooth 121 in the jawbone. The appliance may include a housing 110 (eg, a continuous polymer shell or a segmented shell) having tooth-receiving chambers 111 that accommodate and resiliently reposition teeth 121 . Appliances or parts thereof can be manufactured indirectly using a physical model of the teeth. For example, an appliance (eg, a polymer appliance) can be formed using a physical model of the tooth and suitable layers of polymeric material. In some embodiments, the physical appliance is fabricated directly from a digital model of the appliance, eg, using cumulative fabrication techniques. Appliances may fit on all of the teeth present in the upper or lower jaw, or less than all of the teeth. The appliance may be specifically designed to accommodate the patient's teeth (eg, the topography of the tooth recei...
