  • Patent number: 11957529
    Abstract: The endodontic point containing ultrasonic deformable material is a filler for root canal therapy that decreases in viscosity when subjected to ultrasonic waves. Once the point is inserted into a prepared tooth space, such as a prepared and cleaned root canal, the point is subjected to ultrasonic waves. The ultrasonic waves cause the viscosity of the point to lower, thus allowing the point to flow into voids in the tooth space and allow air to escape from the voids. The point then hardens and remains in the shape acquired when at low viscosity once application of the ultrasonic waves is stopped.

  • Patent number: 11931221
    Abstract: A disposable, self-inflatable, matrix (tooth dam) used to form a temporary, removeable side wall for the placement of a tooth filling material. It has an array of three concavities (distal, central and proximal) formed in a polymer wrap that has a planar substrate sheet affixed across the front face of the wrap. The distal air chamber has a volume that equals or exceeds the combined volume of the central and proximal air chambers. Directly below the distal concavity on the inner face of the planar substrate is an adhesive region. When the distal air chamber is depressed, the air within inflates the other air chambers and it is retained in its compressed state by the adhesive region. The remaining air chambers press against one tooth and exert enough force to elastically secure the planar panel around the adjacent tooth. It prevents the tooth filling material from leaving the prepared tooth and entering the space between.

  • Patent number: 11896459
    Abstract: A method of placing a dental implant analog in a physical model for use in creating a dental prosthesis is provided. The physical model, which is usually based on an impression of the patient's mouth or a scan of the patient's mouth, is prepared. The model is scanned. A three-dimensional computer model of the physical model is created and is used to develop the location of the dental implant. A robot then modifies the physical model to create an opening for the implant analog. The robot then places the implant analog within the opening at the location dictated by the three-dimensional computer model.

  • Patent number: 11896455
    Abstract: A method for generating a digital model of dentition, executed at least in part by a computer, acquires a 3-D digital mesh that is representative of the dentition along a dental arch, including includes braces, teeth, and gingival tissue. The method modifies the 3-D digital mesh to generate a digital mesh dentition model by processing the digital mesh and automatically detecting one or more initial bracket positions from the acquired mesh, processing the initial bracket positions to identify bracket areas for braces that lie against tooth surfaces, identifying one or more brace wires extending between brackets, removing one or more brackets and one or more wires from the dentition model, and forming a reconstructed tooth surface within the digital mesh dentition model where the one or more brackets have been removed. The modified 3-D digital mesh dentition model is displayed, stored, or transmitted over a network to another computer.
