  • Patent number: 10792131
    Abstract: An improved denture system is disclosed. An improved denture system has a support bar and an artificial denture base. The denture base has an oversize cutout and a corresponding cavity and the support bar has a plurality of reference posts which mechanically interface with the corresponding cavity so that the support bar is connected to the artificial denture base and provides reinforcement and stability to the denture system. The shape and position of the reference posts fully constrains the support bar in a fixed position with reference to the denture base. In one embodiment, the denture base snap-fits onto the support bar.

  • Patent number: 10779911
    Abstract: An element intended for an orthodontic system comprises: a fixing surface to be attached to the wall of a tooth; a body, having sides counterposed with respect to the fixing surface and defining a groove passing through sides, for housing an arch wire that can be removed and protrudes while being kept in the groove through at least one of sides with respect of the element; a slit passing through the sides toward the groove in order to assemble the archwire in the groove. In this way the play between the arch wire and the hole is lower than the space between the archwire and the groove, in order to keep the archwire in the body.

  • Patent number: 10765495
    Abstract: A dental device comprises: a dental implant comprising a core enveloped by an expandable anchor comprising a plurality of joined segments. Prior to insertion of the core into the expandable anchor a carrier apically displaces within the expandable anchor, generating an expansion force causing the plurality of joined segments to be displaced linearly away from the central axis of the implant where the coronal and apical ends of each joined segment are displaced in parallel paths normal to the central axis of the implant. The core inserts into the expandable anchor to lock the plurality of joined segments in their expanded configuration. At least a first rail on the core is received by a corresponding expandable anchor slot to align the core and expandable anchor and at least a first core and expandable locking lodge engage to lock the core into the expandable anchor.

  • Patent number: 10758330
    Abstract: The invention relates to a mouthpiece (100) for illumination of teeth, e.g. for teeth whitening. The mouthpiece comprises a slab shaped light guide (203), at least one light source arranged for injecting light into the light guide and an optically transparent element (101) arranged to contact the light guide. The optically transparent element has a lower refractive index than the light guide to enable total internal refection of the injected light. Light is coupled out of the light guide by an out-coupling structure (210) and through a part of the optically transparent part located between the light guide and the buccal side of the teeth to illuminated the teeth with uniform light.

  • Patent number: 10729515
    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.

  • Patent number: 10687920
    Abstract: A dental attachment assembly and method anchors a dental appliance with an implant and has an abutment member attached to the implant, a retention member in releasable snap engagement with the abutment member, and a cap secured in a recess of the dental appliance and in releasable swivel engagement with the retention member to position and secure the dental appliance onto the implant. The cap includes a cavity with a rounded, concave inner surface which engages with the retention member, an interior top surface of the cavity with a concave recess extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member within the cap. A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.
