  • Publication number: 20190269485
    Abstract: Methods and apparatuses for generating a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth) including both surface features and internal features. These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth. Any of these methods and apparatuses may use minimum scattering coefficients and/or segmentation to form a volumetric model of the teeth.

  • Publication number: 20190148498
    Abstract: An improved passivation structure for GaN field effect transistor comprising at least one dielectric layer formed on a top surface of a GaN field effect transistor and a passivation layer formed on a top surface of the dielectric layer. The GaN field effect transistor has a gate electrode comprising a Schottky contact metal layer, at least one diffusion barrier metal layer and a high conductivity metal layer. The passivation layer is made of a low cure temperature Polybenzoxazole (PBO) which can be cured at a low-temperature. Thereby the intermixing of the Schottky contact metal layer and the the diffusion barrier metal layer are prevented.

  • Patent number: 10271923
    Abstract: Orthodontic positioning devices, and related methods and systems, are disclosed for use with one or more orthodontic elastic members. The disclosed devices are configured to couple with an orthodontic elastic member so as to react a force from the elastic member into the appliance to, for example, generate traction forces on the patient's teeth to produce a desired occlusion. A positioning device includes a patient removable tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient's teeth. The appliance includes a hook configured to interface with an orthodontic elastic member. The hook can be configured to be offset from a surface of a tooth when the appliance is coupled with the patient's teeth and no elastic member is coupled with the tooth. The hook can be curved so that the hook is more retentive on the aligner. The hook can be reinforced so that the reinforcement resists deformation when the elastic is in place.

  • Publication number: 20190090982
    Abstract: A current digital dental model is received that includes a representation of the set of physical teeth for the patient with the current dental appliance attached to the physical teeth or oral cavity. The current digital dental model is a direct digital scan of the set of physical teeth and the current dental appliance. The physical teeth are at a position in treatment when all or a part of the current dental appliance is desired to be removed from one or more of the set of physical teeth and it is desired to use a subsequent appliance. The current digital dental model is created based a new digital dental model that includes the representation of the set of physical teeth without including the current dental appliance.

  • Publication number: 20190046296
    Abstract: The present disclosure provides method, systems, and devices for expanding arch of teeth. A device for expanding an arch of teeth of a patient can include a removable shell formed of a first material having a number of cavities formed therein. The number of cavities are shaped to receive teeth of a patient. A device for expanding an arch of teeth of a patient can include an arch element extending from the removable shell in a lingual direction and across an arch width of the removable shell. The arch element can be formed of the first material and a second material that is a different material than the first material, can be designed to expand an arch of the teeth of the patient, and can have a width specific to a stage of a treatment plan.

  • Publication number: 20190029522
    Abstract: Methods and apparatuses for 3D imaging (including 3D optical coherence tomography imaging) to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and/or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.

  • Publication number: 20190008617
    Abstract: Data from an intraoral scan is received, the data comprising a plurality of intraoral images of a dental site. At least two intraoral images are identified that comprise a representation of at least a portion of a non-rigid object that was affixed to the dental site at a target area. Image registration is performed between the at least two intraoral images using the non-rigid object identified in the at least two intraoral images. A 3D model of the dental site is generated based on the image registration. A representation of the non-rigid object is subtracted from the 3D model based on the known properties of the non-rigid object. A surface of a portion of the dental site is interpolated where the non-rigid object was located based on a) data for other portions of the dental site and b) the surface of the base of the non-rigid object.

  • Publication number: 20190008612
    Abstract: The present invention relates to systems and methods of developing and tracking delivery and patient progression through an orthodontic treatment plan. One method includes identifying deviations from an orthodontic treatment plan, including receiving a digital representation of an actual arrangement of a patient's teeth after an orthodontic treatment plan has begun for the patient and prior to completion of the orthodontic treatment plan. The method further includes comparing the actual arrangement to a pre-determined planned arrangement to determine if the actual arrangement substantially deviates from the planned arrangement, the comparing comprising matching teeth from a previously segmented model to a surface of an unsegmented representation of the actual arrangement; and calculating one or more positional differences between the actual and planned arrangements of at least some of the corresponding teeth.
