Patent number: 8506297Abstract: A dental modal for making a dental prosthesis has a base body formed with model teeth and model gingiva and with a cutout in an edentate area and with a hole in a floor of the cutout. A plate is releasably fittable complementarily in the cutout and is formed with a hole aligned with the hole of the cutout. A gingiva mask is fittable on the plate in the cutout and is in turn formed with a hole aligned with the holes of the plate and of the cutout. A model implant insert is releasably fittable in the holes of the mask, plate, and cutout and carries a model implant or an implant-screw mockup.Type: GrantFiled: March 19, 2012Date of Patent: August 13, 2013Assignee: DREVE ProDiMed GmbHInventors: Martin Klare, Markus Kaiser, Frank Gischer

Patent number: 8491306Abstract: In general, the invention relates to techniques for registering a three-dimensional (3D) coordinate system of a physical model of a patient's tooth structure to a 3D coordinate system of a virtual model of the same tooth structure. Techniques are described to register the complex geometries of the physical and virtual tooth structures by using a known physical characteristic of a pedestal associated with the physical model.Type: GrantFiled: August 3, 2005Date of Patent: July 23, 2013Assignee: 3M Innovative Properties CompanyInventors: Richard E.

Patent number: 8459995Abstract: A pinless dental articulator includes a work tray, a retention pocket, and a monorail formed by a plurality of upwardly tapering cylinders which allow jelly or stone to slide out of the retention pocket when the work tray is turned upside down. The work tray has a ledge which stabilizes a rotatable arm that retains the jelly or stone in the retention pocket. A method of using the articulator includes the steps of installing the locking arm onto the stabilizing ledge of the work tray, rotating the locking arm into a closed position on the stabilizing ledge, pouring jelly into the retention pocket, installing a height-adjusting post in the work tray, tightening a fastener against the post in order to keep the post in an upright position, and placing a small tray with at least one negative tooth impression on top of the jelly.Type: GrantFiled: July 16, 2012Date of Patent: June 11, 2013Inventor: Ilya Aronov

Patent number: 8457772Abstract: Presented herein are methods and devices for designing dental components, such as physical models of a patient's anatomy, crowns and bridges. An operator of a prosthetic designing system can receive information, such as from a scanner, which provides information on the topology of the patient's dentition. The operator can use this information to design a custom prosthetic to fit the patient. Part of the designing process involves using a finish line defined for a preparation as a segmentation line for a physical die corresponding to the preparation, and using a path of draw line as an insertion axis line for a dental prosthetic.Type: GrantFiled: February 10, 2010Date of Patent: June 4, 2013Assignee: Biocad Medical, Inc.Inventors: David Giasson, Philippe-Armand Laberge, Marc Bedard, Urban Nilsson, Per-Olof Karlsson, Anna Persson

Patent number: 8442283Abstract: Embodiments of the invention provide methods and systems for generating a color-textured three-dimensional dental model that is specific to a patient. According to one embodiment, generating a patient-specific color-textured three-dimensional dental model can comprise obtaining a three-dimensional dental model of a patient. For example, obtaining the three-dimensional dental model can comprise obtaining volumetric image data of a dentition of the patient and generating the three-dimensional dental model based on the volumetric image data. Two-dimensional intra-oral image data of the patient can also be obtained. For example, obtaining the two-dimensional intra-oral image data can comprise obtaining a plurality of photographs. The patient-specific color-textured three-dimensional dental model can be generated based on the three-dimensional dental model and the two-dimensional intra-oral image data.Type: GrantFiled: August 28, 2007Date of Patent: May 14, 2013Assignee: Anatomage Inc.Inventor: Woncheol Choi
