  • 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.

  • Patent number: 10258434
    Abstract: A low profile winged impression post having snap-in features eliminates the need for individual impressions of the mandibular and maxillary arches as well as a separate bite registration when registering a dental implant. The low profile impression post is retained by a press fit which eliminates the cumbersome task of screwing in the implant post. The time and steps needed to produce a stone model for construction are shortened. The same low profile impression post can be scanned optically for accurate placement in a virtual three dimensional space model of the jaw. A physical model can be generated in rigid polymer from the virtual scan data.
