Abstract: The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment placement structure. One dental attachment placement apparatus includes a body having an attachment placement surface that is to be placed on an attachment affixing surface of a tooth and wherein the attachment placement surface includes a portion that is shaped to allow placement of an attachment at a particular position on the affixing surface of the tooth and a portion of the body having a contour that is shaped to correspond with a contour of an alignment surface of a tooth and when the contour of the body and the corresponding contour is aligned, the attachment is located at the particular position and can be secured to the affixing surface of the tooth.

Abstract: Embodiments relate to an aligner breakage solution that tests damage to an aligner using machine learning. A method includes processing data from a digital design for an orthodontic aligner by a trained machine learning model and outputting, by the trained machine learning model, a probability that the orthodontic aligner associated with the digital design will be damaged during manufacturing of the orthodontic aligner. The method further includes making a comparison of the probability that the orthodontic aligner associated with the digital design will be damaged during manufacturing of the orthodontic aligner to a probability threshold and determining whether the orthodontic aligner is a high risk orthodontic aligner based on a result of the comparison. Responsive to determining that the orthodontic aligner is a high risk orthodontic aligner, the method includes performing at least one of a) a corrective action or b) selecting a manufacturing flow for high risk orthodontic aligners.

Abstract: A dental appliance having an integrally formed reservoir and/or an ornamental design integrated thereon. The ornamental design can be selected or customized by a patient. The design can be created by directing energy to the dental appliance to alter a material property of at least a portion of the appliance to create the design. Alternatively, a groove or recess can be formed on a surface of the appliance to either mechanically retain an ornamental design or the groove or recess can be filled with ink to form the design. The appliance, including the integrally formed reservoir, can be formed using direct fabrication techniques.

Abstract: Detection of placement of dental aligners in patient mouth on teeth for indication of wearing compliance. Described herein are apparatuses and methods for detecting wearing, including compliance. In some variations these apparatuses and methods may include a sensor configured to detect deflection of the one or more deflectable structures. In some variations, these apparatuses and methods may include a proximity sensor coupled to the appliance shell and configured to generate sensor data when in proximity with intraoral tissue.

Abstract: A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.

Abstract: A series of appliances including a first shell and a second shell can be designed to incrementally implement a treatment plan. The first and second shells can have cavities designed to receive teeth of a jaw. A first number of bite adjustment structures can be formed of a same material as the first shell and extend from the first cavities and be designed to interface with teeth of a second jaw. The first number of bite adjustment structures can have a first shape and location. A second number of bite adjustment structures can be formed of a same material as the second shell and extend from the second cavities and be designed to interface with teeth of the second jaw. The second number of bite adjustment structures can have a second shape and location, different than the first shape and location.
