  • Patent number: 12213859
    Abstract: Protrusions or holes with jagged edges formed on the lingual side of invisible aligner trays are provided. The protrusions or holes include two components and serve to irritate the tongue causing it to retract away from the incisors thus eliminating intruding force otherwise exerted by the tongue. A clear corrugated material is provided which is suited for making the aligner trays having the protrusions which otherwise would be difficult with standard thick material used. The lingual side protrusions are added by computer to the impressions taken from a patient's teeth such that the protrusions are formed on the dental model used to make the aligner trays.

  • Patent number: 12178680
    Abstract: A multi-unit abutment aligning a dental implant and a screw-attached prosthesis with copings is disclosed. The multi-unit abutment has a threaded base post for attachment to the implant and a ball portion. A swivel shell surrounds the ball and may be fixed in position with a lock screw. A drive feature on the ball allows a tool passing through the lock screw to drive the base post into the implant with the multi-unit assembly in a linear configuration. The swivel shell is then positioned and fixed at a desired tilt and azimuthal angle. The swivel shell has a mating surface for a coping. The lock screw remains accessible through an aperture in the coping when the prosthesis is positioned on the implant abutments. Different embodiments are disclosed for capturing the swivel shell on the ball. Methods for improving passive alignment of the prosthesis to the implants are described.
