Abstract
Provided is a method in which a computational device generates a design of a negative mold of teeth. The negative mold of the teeth is fabricated from the design of the negative mold. An aligner is formed using the fabricated negative mold. Provided also is a negative mold of teeth for fabricating a positive model of the teeth for an aligner. The negative mold comprises a tooth surface, and an identity tracking entity coupled to the tooth surface to provide identification.
Claims23
A method of manufacturing an orthodontic aligner for a patient, comprising:
- generating, via a computational device, a design of a negative mold of the patient's teeth, the design including a digital data set having identification information to at least identify the patient;
- fabricating a negative mold of the patient's teeth from the design with an identity tracking entity, including the identification information, exposed at a surface of the negative mold;
- forming an aligner using the fabricated negative mold;
- after forming the aligner, scanning the identification information;
- and
- modifying the formed aligner based on the scanned identification information.

A method, comprising:
- generating, via a computational device, a design of a negative mold of teeth, wherein the design is a digital data set and identification information is associated with the digital data set;
- fabricating, by a rapid prototyping machine, the negative mold of the teeth from the design of the negative mold, wherein the negative mold corresponds to a mold and is comprised of an identity tracking entity to provide the identification information;
- and
- generating a positive model of the teeth from the fabricated negative mold by transferring material into the negative mold, wherein the positive model corresponds to a cast and the identity tracking entity is transferred to the positive model;
- and
- thermoforming an aligner over the positive model.
