  • Patent number: 10076391
    Abstract: The present invention relates to method and system for bite registration using multiple bite registrations. In this method or system, when both the 3D teeth model of the upper jaw and the 3D teeth model of the lower jaw are successfully aligned with the bite surface, the bite surface with the 3D teeth models of the upper jaw and the lower jaw is displayed for further evaluation; the bite surfaces selected by the user are combined to generate a final bite registration. Using multiple bite surfaces for registration improves the accuracy.

  • Patent number: 10052175
    Abstract: A magnetic removable orthodontic assembly for moving selected teeth of a patient includes metal engagement plates that are fixed in place in alignment with the selected teeth. A series of wire guides that contain magnets are contacted to the selected teeth by way of engagement with the teeth engagement plates. The engagement plates have first engagement members that engage complementary-shaped second engagement members on the wire guides in a removable fashion. The wire guides are mounted in a pattern to an archwire. The wire guides may be disengaged from their corresponding engagement plates so that the wearer of the appliance can remove and re-engage the device when necessary without having an orthodontist do it.

  • Patent number: 10045834
    Abstract: The present disclosure is directed, at least in part, to a self ligating orthodontic bracket system that includes a rotatable member for securing an archwire within a slot of a bracket. Embodiments of the orthodontic bracket system disclosed herein include a bracket body containing the archwire slot as well as tie wings for attaching various orthodontic devices (e.g., elastomeric bands) to the bracket. The rotatable member is rotatable in a first direction (e.g., counter clockwise) relative to a body of the bracket for securing or locking the archwire within the slot, and for rotating in an opposite direction (e.g., a clockwise direction) relative to the bracket body for unsecuring or unlocking the archwire so that it is substantially unrestrained from exiting the slot.

  • Patent number: 10032271
    Abstract: Methods for recognizing or identifying tooth types using digital 3D models of teeth. The methods include receiving a segmented digital 3D model of teeth and selecting a digital 3D model of a tooth from the segmented digital 3D model. An aggregation of the plurality of distinct features of the tooth is computed to generate a single feature describing the digital 3D model of the tooth. A type of the tooth is identified based upon the aggregation, which can include comparing the aggregation with features corresponding with known tooth types. The methods also include identifying a type of tooth, without segmenting it from an arch, based upon tooth widths and a location of the tooth within the arch.

  • Patent number: 10028810
    Abstract: A method of capturing data from a patient's dentition with the steps of positioning a first optical sensor relative to patient's dentition, capturing the shape of a tooth in the patient's dentition, independent from capturing the shape, measuring a color at a location on the tooth, and providing a correlation between the location of the color and a coordinate in the captured shape. The invention helps providing a dental restoration at a relatively high optical, mechanical, and geometric quality.

  • Patent number: 10016241
    Abstract: A method and system for planning a creation of a cement bore in a bone comprises obtaining a virtual model of a bone, the model of the bone including a proximal bone surface, a distal bone surface, and a depth profile between the proximal bone surface and the distal bone surface. A planned positioning of a first implant selected to be implanted in the proximal bone surface is obtained. An identity of at least one tool used to alter the proximal bone surface to receive the first implant in the planned positioning and obtaining geometry data for the at least one tool is obtained. A cement bore required in the bone using the geometry data of the at least one tool and the planned positioning of the first implant is generated. The virtual model of the bone with the cement bore indicative of a relation between the cement bore and the distal bone surface is output.

  • Patent number: 10004572
    Abstract: A processing device receives an intraoral image of a first intraoral site. The processing device selects a portion of the intraoral image that depicts a portion of the first intraoral site. The processing device locks at least the portion of the intraoral image. The processing device may then generate a model comprising the first intraoral site based at least in part on the locked intraoral image, wherein the portion of the intraoral image is used for a first region of the model, and wherein data from one or more additional intraoral images that also depict the portion of the first intraoral site is not used for the first region of the model.

  • Patent number: 9978172
    Abstract: The invention relates to a method for recording individual three-dimensional optical images (1) to form a global image (50) of a tooth situation comprising an upper jaw (2) and a lower jaw (3). A first 3D model (6) of a first subsection of the upper jaw and a second 3D model (8) of a second subsection of the lower jaw are produced from the individual images. Subsequently, a geometric positional relationship between the first 3D model (6) and the second 3D model (8) is determined, said positional relationship being determined by using a lateral image (20, 21, 22) and/or using a contact pattern (31, 32). Said lateral image (20, 21, 22) comprises an image area which comprises at least part of the first subsection of the upper jaw (2) and at least part of the second subsection of the lower jaw (3). Said contact pattern comprises several contact areas (31, 32) between the upper jaw and the lower jaw. Said contact pattern (30, 31, 32) is measured by means of an occlusion paper (29).

  • Patent number: 9949809
    Abstract: Non-customized dental treatment trays used to provide a desired treatment are formed from elastomeric silicone or silicone-like material. They may be molded from a two-part liquid silicone composition or a silicone-like TPE material (e.g., preferably SEBS and/or VERSAFLEX™ thermoplastic elastomer). The dental treatment trays possess high adaptability, flexibility, softness, and elastic elongation while also exhibiting resiliency in order to readily conform to the ridges, depressions and contours of a person's teeth during use. The trays possess a greater ability to adhere to a person's teeth compared to non-elastomeric thermoplastic materials. Due to their high adaptability and conformability, the non-customized dental trays behave like a semi-custom dental tray when placed over conformed to a person's teeth, particularly when used in combination with a sticky, viscous treatment composition.
