Dental articulators and components of dental models as described herein use a positioning key to encode positional information for components of the dental model, and/or a reference grid on mounting surfaces to enforce local accuracy of fabricated parts against a fixed reference array.Type: GrantFiled: February 23, 2010Date of Patent: February 12, 2013Assignee: 3M Innovative Properties CompanyInventors: Patrick Colm Dunne, Eric B. Paley, Micah J. Rosenbloom, Michael Patrick Girard

Patent number: 8364301Abstract: A method is set forth for making a computer model of patient's jaws on the basis of digital information. Digital data about the jaws, teeth, soft tissues and artificial teeth is joined in computer space to create aesthetic and functional plans for the removal of teeth, shaping of supporting bone and placement of dental implants. Artificial teeth and pre-manufactured prosthetic devices are made and attached to the dental implants at the time of surgery. The aesthetic and functional position of artificial teeth is determined prior to surgical removal of natural teeth and the ideal position of implants and the proper form of the remaining bone are determined prior to surgery. Surgical guides used to shape bone, record occlusal orientation and position dental implants are manufactured using computer milling or layered manufacturing.Type: GrantFiled: November 16, 2010Date of Patent: January 29, 2013Assignee: Bankruptcy Estate of Voxelogix CorporationInventor: Stephen M.

Patent number: 8355816Abstract: To make it possible to teach a grasping action for a work object whose shape and 3D position are unknown to a robot by an intuitive and simple input operation by an operator. a captured image of the working space is displayed on a display device; (b) an operation in which a recognition area including a part of a work object to be grasped by a hand is specified in two dimensions on an image of the work object displayed on the display device is received; (c) an operation in which a primitive shape model to be applied to the part to be grasped is specified from among a plurality of primitive shape models; (d) a parameter group to specify the shape, position, and posture of the primitive shape model is determined by fitting the specified primitive shape model onto 3D position data of a space corresponding to the recognition area; (e) a grasping pattern applicable to grasping of the work object is selected by searching a database in which grasping patterns applicable by a hand to primitive shape models are stored.Type: GrantFiled: February 3, 2009Date of Patent: January 15, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Fuminori Saito

Patent number: 8352060Abstract: A method and system for fabricating a dental prosthesis are provided. High resolution digital scanned images of a patient's oral structures are acquired. Three dimensional (3D) cone beam X-ray images of hard and soft oral tissues are acquired. The scanned images are integrated with the 3D cone beam X-ray images in a 3D space to obtain combined three dimensional images of the oral structures. The occlusal relationship between upper and lower oral structures are digitally simulated using the combined three dimensional images. The dental prosthesis is digitally modeled for planning intra-oral positioning and structure of the dental prosthesis. The digital dental prosthesis model is refined based on simulated force tests performed for assessing interference and retention of the digital dental prosthesis model. A prospective dental prosthesis model is created based on the refined digital dental prosthesis model. The dental prosthesis is fabricated based on a verified prospective dental prosthesis model.Type: GrantFiled: May 5, 2010Date of Patent: January 8, 2013Assignee: Hankookin, LLC.Inventors: James Jiwen Chun, Angela Soyoung Chun, Andrew Youngho Chun, Jennifer Miseong Chun

Patent number: RE44696Abstract: A method for manufacturing a ring (i.e. class, championship, or affiliation) begins by receiving order data specifying a series of personalization elements, such as the addition of text and icon designs. A geometric model for each personalization item is constructed. To assemble text panels, the operating system provides font geometry for a desired TrueType font. Then a set of splines are created from the font geometry and are then tessellated to generate polyline sets of data, which are then spaced and mapped between two boundary curves. The personalization elements are then projected onto one of the model's 3D surfaces. A set of machining instructions for a milling machine is generated by obtaining a set of machining pattern strategies, generating a set of curves, projecting the toolpath onto the surface of the ring to calculate the 3D toolpath, and rotating it to a desired angle.Type: GrantFiled: September 20, 2011Date of Patent: January 7, 2014Assignee: Jostens, Inc.Inventors: Timothy D. Saarela, Carlos D. Carbonera, Michael J. Frisch, Yuriy Malinin
