  • Publication number: 20180194039
    Abstract: A mold includes a main body and a separable feature. One or more first weakened regions join the separable feature to the main body. The one or more first weakened regions are breakable to enable the main body to be removed from a shell independently of the separable feature after the shell is formed over the mold. The main body includes a first section and a second section that are at least partially separable at one or more second weakened regions to enable the first section to be removed from the shell independently of the second section after the shell is formed over the mold.

  • Publication number: 20180132975
    Abstract: The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, and providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.

  • Publication number: 20180000564
    Abstract: A plastic shell such as an orthodontic aligner has an interior shape that substantially conforms to a current or future dental arch of a patient. The plastic shell includes a hollow feature comprising a cavity. The plastic shell additionally includes an object inserted into the cavity, wherein the object provides structural strength to the plastic shell at a location of the hollow feature and does not interfere with a fit of the plastic shell onto the dental arch of the patient.

  • Publication number: 20170209238
    Abstract: The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a removable dental appliance includes a shell having a number of tooth apertures configured to receive and reposition a number of teeth of a patient along one jaw of a patient, a repositioning jaw element that extends from a buccal or lingual surface of the shell, the element having a first outer surface oriented to face the tongue of the patient surface and a second outer surface oriented to face the cheek of the patient, and a reinforcement member formed along at least one of the first and second outer surfaces to provide reinforcement of the repositioning jaw element.

  • Publication number: 20160361139
    Abstract: The present disclosure provides methods, computing device readable medium, devices, and systems having a dental appliance binding structure. One method can include to create a treatment plan based on a virtual model of a jaw of a patient, wherein the treatment plan includes use of a dental appliance having a first surface that defines a plurality of cavities shaped to receive a plurality of teeth, modify the virtual model of the jaw in a first configuration to include a virtual binding structure on a second surface, the platform shaped to receive a specialized feature that provides one or more force characteristics, select a particular specialized feature as an attachment to the dental appliance, and adjust the virtual model of the jaw from a first configuration to a second configuration, based at least in part on a modeled force provided by the virtual binding structure and the particular specialized feature.

  • Publication number: 20160199216
    Abstract: Improved systems, methods, and devices for treating sleep apnea are provided herein. In one aspect, an intraoral appliance for treating sleep apnea in a patient comprises an appliance shell comprising a plurality of cavities shaped to receive teeth of a jaw of the patient. The appliance shell can comprise an advancement structure arranged to interact with an opposing jaw of the patient so as to displace the lower jaw anteriorly relative to the upper jaw. The plurality of cavities can comprise cavity geometries shaped to reduce repositioning of one or more received teeth elicited by displacement of the lower jaw anteriorly relative to the upper jaw.
