  • Publication number: 20220374119
    Abstract: A method for treating a subject's teeth. A target configuration for the subject's teeth is determined. Receiving features are produced on a dental base in response to the target configuration, the receiving features being configured to receive physical tooth models. The physical tooth models are assembled on the dental base to form a physical arch model. A dental aligner is produced using the physical arch model to move the subject's teeth to the target configuration.

  • Patent number: 8087932
    Abstract: 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.

  • Publication number: 20090053669
    Abstract: 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.

  • Publication number: 20060127857
    Abstract: 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.
