Abstract: A system is configured to manufacture an aligner. The system includes a heating section configured to heat a sheet of plastic to generate a heated sheet of plastic. The system further includes a plate configured to secure a mold associated with a dental arch of a patient. The plate includes a keyway and a pin. The mold includes a first feature configured to interface with the keyway and a second feature configured to interface with the pin. The system further includes a thermoforming chamber configured to thermoform the heated sheet of plastic to the mold that is secured to the plate via a first interface of the keyway with the first feature and a second interface of the pin with the second feature to generate a thermoformed sheet of plastic. The system further includes a cutting tool configured to trim the aligner from the thermoformed sheet of plastic.

Abstract: A system includes a heating section configured to heat a sheet of plastic to generate a heated sheet of plastic. The system includes a plate configured to secure a mold associated with a dental arch of a patient. The plate includes a locking mechanism. The mold includes feature configured to interface with the locking mechanism. The system further includes a thermoforming chamber configured to thermoform the heated sheet of plastic to the mold that is secured to the plate via an interface of the locking mechanism with the feature to generate a thermoformed sheet of plastic. The locking mechanism is configured to extend through the mold and overlap an upper surface of the mold to lock the mold in a z-direction that is orthogonal to a plane defined by the plate. The system further includes a cutting tool configured to trim an aligner from the thermoformed sheet of plastic.

Abstract: Embodiments relate to thermoforming multiple aligners simultaneously. In one embodiment, an aligner manufacturing system includes a plate, a heating section, and a thermoforming chamber. The plate is configured to secure a first mold of a first dental arch and a second mold of a second dental arch. The heating section is configured to heat a sheet of plastic to generate a heated sheet. The thermoforming chamber is configured to simultaneously thermoform the heated sheet over the first mold of the first dental arch and the second mold of the second dental arch to form a first aligner shaped to fit the first dental arch and a second aligner shaped to fit the second dental arch.
