Publication number: 20230069231Abstract: The invention relates to a computer-implemented method for adjusting a position of artificial teeth of a denture. A digital 3D model of the denture comprising at least a denture part is provided. The denture part is configured for a jaw of a patient and comprises a dental arch with a plurality of artificial teeth arranged in an artificial gingiva. A deformable gingiva section of the artificial gingiva is defined between the teeth of the plurality of artificial teeth and a fixed gingiva section of the artificial gingiva with a fixed geometrical form. The dental arch is moved as a whole relative to the fixed gingiva section in order to adjust the position of the dental arch. A geometrical form of the deformable gingiva section is deformed due to the moving of the dental arch, whereas the fixed gingiva section maintains the fixed geometrical form.Type: ApplicationFiled: September 1, 2021Publication date: March 2, 2023Inventors: Maik GERTH, Paul SCHNITZSPAN, Grigorios KARANGELIS

Patent number: 11337781Abstract: A method for producing a tooth replacement part to be secured on an implant, based on a 3D model of the tooth replacement part with a surface and with a continuous screw channel with an initial shape in the form of a cylindrical barrel, with a first and a second end, wherein a cross sectional area of the screw channel is designed to be constant and/or to increase in size towards the second end of the screw channel. A 3D model of an inlay with a jacket surface, an upper face and a lower face is generated. A part of the surface of the 3D model of the tooth replacement part that is cut out through the second end of the final shape of the screw channel is used as the upper face and the jacket surface is configured as a negative form of a part of the final shape of the screw channel that adjoins the second end.Type: GrantFiled: July 6, 2016Date of Patent: May 24, 2022Assignee: DENTSPLY SIRONA INC.Inventors: Paul Schnitzspan, Thorsten Jordan, Friedemann Roessler

Patent number: 11259903Abstract: The invention relates to a specimen part for creating a stress-free fit, a so-called passive fit, of implant-supported and/or abutment-supported bridges and bars by means of a CAD/CAM tool for the creation of restorations, and to a method for creating a restoration from a digital model of a patient's jaw provided with at least two implants and/or abutments. The model is determined by means of an intraoral scan. In order to improve the precision of restorations and to shorten the production process, provision is made that the specimen part per implant and/or abutment has a scannable structure, preferably at a defined distance and angle to the implant and/or abutment.Type: GrantFiled: February 19, 2016Date of Patent: March 1, 2022Assignee: DENTSPLY SIRONA INC.Inventor: Paul Schnitzspan

Patent number: 10729517Abstract: A method is proposed for ascertaining the spatial positions and orientations of at least two implants anchored in a jaw of a patient, said method having the following steps: 1. An adhesive bond aid is produced that bridges the implants and has negative molds of adhesive caps, wherein the negative molds fit on the adhesive caps if these are affixed to the implants, and wherein the negative molds allow a clearance relative to the adhesive caps. 2. The adhesive caps are affixed to the at least two implants in the jaw of the patient. 3. The adhesive bond aid is positioned over the adhesive caps. 4. The clearance between the adhesive caps and the negative molds is filled with adhesive. 5. The adhesive is cured. 6. The adhesive caps are released from the implants. 7. The obtained adhesion key is removed from the patient.Type: GrantFiled: December 18, 2015Date of Patent: August 4, 2020Assignee: DENTSPLY SIRONA Inc.Inventors: Paul Schnitzspan, Volker Wedler
