Abstract

Embodiments relate to a pre-fabricated attachment for fabricating custom objects. In one embodiment, a system includes a mold and a pre-fabricated attachment. The mold includes a physical model of a dental arch of a patient and one or more first features. An orthodontic aligner is to be formed over the physical model. The pre-fabricated attachment includes one or more second features configured to removably attach to the one or more first features. The pre-fabricated attachment further includes a traceability component configured to be used to determine one or more identifiers corresponding to the mold. The pre-fabricated attachment further includes a handling component configured to be secured by a robot or person to transport the mold and pre-fabricated attachment during production of the orthodontic aligner. The pre-fabricated attachment may be reused.

a traceability component configured to be used to determine one or more identifiers corresponding to the mold.

2. The system of claim 1 , wherein the traceability component comprises one or more of a radio-frequency identification (RFID) tag or a near field communication (NFC) tag.

3. The system of claim 1 , wherein the traceability component comprises one or more of a data matrix, a barcode, a matrix barcode, a two-dimensional barcode, a three-dimensional barcode, an annotation tag, a digital identifier, or an optical identifier.

4. The system of claim 1 , wherein the one or more identifiers comprise a patient identifier (PID) of the patient and a treatment stage identifier corresponding to the mold, wherein the one or more identifiers are stored in the traceability component.

5. The system of claim 1 , wherein an attachment identifier is stored in the traceability component, wherein a database associates the attachment identifier with a patient identifier (PID) and a treatment stage, wherein the attachment identifier and the database are to be used to identify one or more production operations corresponding to the PID and the treatment stage during production of the orthodontic aligner.

6. The system of claim 1 , wherein the pre-fabricated attachment further comprises:

a handling component configured to be secured by a robot or person to transport the mold and the pre-fabricated attachment during production of the orthodontic aligner.

7. A method comprising:

identifying a mold comprising a physical model of a dental arch of a patient and one or more first features, the physical model comprising a base portion and a teeth portion, the teeth portion comprising a plurality of teeth extending from a first distal end of the dental arch to a second distal end of the dental arch, wherein an orthodontic aligner is to be formed over the plurality of teeth of the physical model, the plurality of teeth of the physical model being shaped to correspond to a plurality of tooth-receiving cavities of the orthodontic aligner, the one or more first features being associated with the base portion of the physical model;

causing a pre-fabricated attachment to be removably attached to the mold via the one or more first features at the base portion of the physical model and one or more second features of the pre-fabricated attachment, wherein the one or more first features comprise a flattened area forming one or more holes, wherein the one or more second features comprise one or more protrusions to attach to the flattened area via at least one of the one or more holes;

associating a traceability component of the pre-fabricated attachment with a patient identifier (PID) of the patient and a treatment stage corresponding to the mold; and

causing a handling component of the pre-fabricated attachment to be secured by a robot or a person to transport the mold and the pre-fabricated attachment during production of the orthodontic aligner.

8. The method of claim 7 further comprising:

after forming the orthodontic aligner using the mold, causing the pre-fabricated attachment to be removed from the mold; and

causing the pre-fabricated attachment to be attached to a second mold.

9. The method of claim 8 further comprising:

re-coding the pre-fabricated attachment with a second PID and a second treatment stage associated with the second mold; or

associating an identifier of the pre-fabricated attachment with the second PID and the second treatment stage via a database.

10. The method of claim 7 , wherein a plurality of molds are disposed on a surface, the method further comprising:

determining positional information of the mold based on a location of the mold on the surface; and

determining the PID and the treatment stage based on the positional information of the mold.

11. The method of claim 7 , wherein the causing of the pre-fabricated attachment to be attached to the mold comprises one or more of:

inserting a latch of the pre-fabricated attachment into the at least one of the one or more holes formed by the mold;

mounting the pre-fabricated attachment into the mold; or

screwing the pre-fabricated attachment into the mold.

12. The method of claim 7 further comprising:

causing a sensor of at least one of a laser cutting machine or a milling machine to read the traceability component responsive to the traceability component being within a threshold distance of the sensor.

13. The method of claim 7 , wherein subsequent to the causing of the pre-fabricated attachment to be attached to the mold, the pre-fabricated attachment remains attached to the mold during the production of the orthodontic aligner, the production comprising one or more of thermoforming, laser cutting, milling, or polishing.

14. A pre-fabricated attachment for a mold, the pre-fabricated attachment comprising:
