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.

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.

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, 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, and adjusting the position of the repositioning jaw elements on the first shell and the second shell to comply with a number of constraints. 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.

Abstract: A mold includes a first section, a second section, and a weakened region that joins the first section to the second section. The weakened region is breakable, deflectable, or deformable in response to a first threshold force to enable the first section to be removed from a shell independently of the second section after the shell is formed over the mold. The first threshold force is less than a second threshold force that would damage or permanently deform the shell. The first section is a first mold of at least a portion of one or more first teeth of a dental arch and the second section is a second mold of at least a portion of one or more second teeth of the dental arch.

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.

Abstract: A method includes determining a first shape of a main body of a mold associated with a dental arch for a patient. The method further includes determining a second shape of a separable feature of the mold. The method further includes determining a third shape and configuration of a receiving element of the main body to receive the separable feature. The method further includes outputting instructions for fabricating the separable feature and the main body that includes the receiving element for receiving the separable feature.
