Patent number: 8087932Abstract: A method of correcting a dental arch model so that it accurately reflects the current arrangement of a subject's teeth includes positioning a plurality of tooth models in a corrected arrangement using a representation of at least a portion of a subject's current dental arch (wherein the tooth models comprise models of the subject's teeth having fiduciary markers), and producing a base plate configured to hold the plurality of tooth models in the corrected arrangement. The representation of the current arrangement may be, for example, a physical impression of the subject's teeth, a 3D scan or one or more 2D scans of the subject's teeth.Type: GrantFiled: October 3, 2007Date of Patent: January 3, 2012Assignee: Align Technology, Inc.Inventor: Frank Zhenhuan Liu

Publication number: 20090053669Abstract: A casting chamber for casting a physical tooth model representing a patient's tooth includes a chamber body and a lid. The chamber body includes a cavity adapted to hold a negative impression of the patient's tooth and to receive a cast material, wherein the negative impression and the chamber body are registered by a registration unit. The chamber lid is configured to seal the cast material in the casting chamber to permit the casting material to solidify in the casting chamber to form a physical tooth model representing the patient's tooth.Type: ApplicationFiled: September 16, 2008Publication date: February 26, 2009Applicant: ALIGN TECHNOLOGY, INC.Inventors: FRANK ZHENHUAN LIU, HUAFENG WEN

Publication number: 20060127857Abstract: Systems and methods are disclosed that produce a physical dental arch model having at least two adjacent physical tooth models and a base configured to receive the physical tooth models. The method includes determining the positions and orientations of the two adjacent physical tooth models in the physical dental arch model and selecting the configurations of pins to be affixed to the bottom of the two adjacent physical tooth models such that the two adjacent physical tooth models do not interfere with each other when the two physical tooth models are mounted to the base by inserting the pins into corresponding sockets in the base.Type: ApplicationFiled: December 14, 2004Publication date: June 15, 2006Inventors: Frank Zhenhuan Liu, Huafeng Wen
