Thermoforming methods of making orthodontic appliances and orthodontic appliances preforms employ a barrier sheet positioned between an appliance sheet and a dental model during the forming step. The thermoformed orthodontic appliances are more pellucid than appliances thermoformed without the barrier sheet.

An oral training appliance for training the tongue and lips of a person is disclosed. The appliance comprises a U shaped body comprising a front section and two arms, an inner wall and an outer wall. A tongue training member extends from the inner wall and is moveable in response to movement by the user's tongue from a rest configuration to a training configuration. The appliance also comprises a lip training member and is moveable in response to movement of a user's lower lip from a rest configuration to a training configuration and the lip training member is biased towards the rest configuration.

A removable dental appliance may include an appliance body at least partially surrounding two or more teeth of a patient. The appliance body may include a first shell shaped to receive a first tooth; a second shell shaped to receive a second tooth; and at least one spring bellows that includes an arcuate displacement extending over and away from at least a portion of an interproximal region between the first tooth and the second tooth to join the first shell and the second shell. The spring bellows is configured to apply a force between the first shell and the second shell to cause movement of at least one of the first tooth and the second tooth toward a desired position when the removable dental appliance is worn by the patient.

In various implementations, computer-implemented method, such as one executed on a computer system or on instructions stored on computer-readable media may include: receiving from a user device associated with a user, a request to access one or more treatment plans for patient; identifying a treatment template for user, the treatment template representing treatment preferences of the user, the treatment template being expressed according to treatment domain-specific protocols; processing the treatment template with the treatment domain-specific protocols to convert one or more parts of the treatment template into one or more runtime elements that interactively display customized user interface elements related to the treatment plan, the customized user interface elements configured to provide one or more customized user interactions with the treatment plan in accordance with the treatment preferences of the user; and providing instructions to display the one or more runtime elements on the user device.

An off-the-shelf oral splint that is operatively secured to the maxilla and mandible to assist in reduction and provide maintenance of reduction of maxillary and mandibular fractures in the edentulous or partially edentulous patient. The oral splint is fabricated into a plurality of standardized sizes. These sizes are determined by imaging a population of jaws, measuring dimensions thereof, manipulating (e.g., calculating the mean) these dimensions, and generating a size that is representative of a subset of that population. This can be done for all sizes that would represent individuals in that population. The splint itself is fabricated virtually by creating “U-shapes”, splitting them horizontally into halves, creating an evacuation channel, and generating a coupling mechanism to hold the halves together. The splint can then be printed or otherwise manufactured.

An oral orthotic device includes a body having a left portion including an upper surface and a right portion including an upper surface. The upper surface of the left portion and the upper surface of the right portion define a plane positioned to extend above an irregular surface defined by teeth of a user. A bite block extends from the upper surface of one of the left portion or the right portion a distance above the plane such that the bite block is disposed on the oral orthotic device exclusively on either the left portion or the right portion. One or more springs extend from the body and are configured to buffer the body from the teeth of the user. A lingual portion is coupled to the left portion of the body and to the right portion of the body. The lingual portion encloses a helical wire.
