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 individual teeth 121 in the jaw. The appliance may include a housing 110 (eg, a continuous polymer shell or a segmented shell) having tooth-receiving chambers 111 that house and elastically reposition teeth 121 . The appliance, or parts thereof, can be manufactured indirectly using a physical model of the teeth. For example, an appliance (eg, a polymer appliance) may be formed using a physical model of the teeth and suitable layers of polymeric material. In some embodiments, the physical appliance is manufactured directly from a digital model of the appliance, for example using cumulative manufacturing techniques. Braces may fit on all, or less than all, teeth present in the upper or lower jaw. The appliance may be specifically designed to accommodate the patient's teeth (e.g., the topography of the tooth chambers matches ...

Abstract

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

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 547,004, filed August 17, 2017, which is incorporated herein by reference. Background technique [0003] The manufacture of treatment plans and aligners is a linear, back-and-forth process with delays between providing feedback and revising the treatment plan, and requires expertise in figuring out which patients' malocclusions are to be corrected. This process is not ideal because it leaves room for error in the treatment planning process. Contents 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 tooth movement constraints. The method may further 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...
