Abstract: Methods for orthodontic treatment planning include modifying a digital picture of a patient based on a tooth model produced during simulated orthodontic treatment after movement of at least one model tooth to produce a modified digital image depicting the at least one model tooth after movement. The method includes matching and morphing information from the digital picture into the modified digital image. Modifying includes matching a model tooth in the T1 model to a tooth in the digital picture and morphing that information into the modified digital image. Morphing may include projecting a model tooth in the T1 model to an image plane of the digital picture and projecting a model tooth from an intermediate T model to the image plane. Parameterization of the projections of each model may be used to develop a pixel correspondence map, which is usable during rendering of a tooth in the modified digital image.

Abstract: A system for orthodontic treatment planning. The system comprises a processor and memory. Computer-program instructions cause the system to display a user interface on a display. The user interface is for a user to input a prescription for treatment of the patient. The user interface provides a plurality of commands for selection. Each command is a one-word instruction, a two-word instruction, or a three-word instruction based on orthodontic nomenclature. The system receives selected two or more of the plurality of commands into the prescription for treatment. The two or more selected commands are to be applied according to a predetermined protocol to the patient's teeth. A database is configured to receive the prescription for treatment of the patient and to contain a plurality of other prescriptions for treatment of other patients. The database is configured to receive a plurality of other prescriptions from a plurality of users of the system.

Abstract: An orthodontic aligner includes a shell defining at least one cavity sized to receive one of a patient's teeth. The cavity includes a lingual portion, a labial portion, and an occlusal portion. A bite structure forms at least a portion of the occlusal portion and is configured to be spaced apart from an occlusal surface of the patient's tooth by a distant sufficient to interfere with full closure of the patient's jaws. The bite structure has a non-planar surface that does not conform to the patient's tooth. The non-planar surface includes at least two spaced-apart projections separated by a boundary. The spaced-apart projections are spherical-like projections or ellipsoidal-like projections. The boundary has a grid-like appearance that spans the bite structure side to side. The spaced-apart projections define a tooth-engaging plane of the bite structure. The bite structure is an integral portion of the shell.

Abstract: An orthodontic bracket axis indicator for use with an orthodontic bracket including a long slot intersecting with an archwire slot having a base surface and first and second opposed slot surfaces extending from the base surface includes an insert having first and second elongate cross members having first and second top surfaces, respectively, and arranged generally perpendicular to each other such that, when viewed from above, the insert has a generally cruciform shape. First and second grooves extend along the first and second top surfaces of the first and second cross members, respectively, and are each configured to receive an orthodontic tool. The first cross member is configured to be received by the archwire slot and the second cross member is configured to be received by the long slot in order to provide an interference fit between the insert and the orthodontic bracket.

Abstract: An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and movable member are made from a transparent or translucent ceramic for improved aesthetics. The bracket body may include one or more stop surfaces that limit movement of the moveable member in the gingival direction. The bracket body may include a support surface that is positioned lingually of a labial edge of the archwire slot. The moveable member may include a bracket-engaging portion having a first surface confronting the bracket body and a slot-covering portion having a second surface confronting the archwire slot, the first and second surfaces being offset from one another.

Abstract: Provided are a system, method, and computer readable storage medium for using a digital reconstruction of a tooth, wherein the digital reconstruction includes a crown and a root. An image of the crown of the tooth is acquired, subsequent to a movement of the tooth. The shape data of the crown is extracted from the image and registered to the digital reconstruction of the tooth.

Abstract: A dental aligner and methods and systems for manufacturing the dental aligner. A boundary contour is defined in a two-dimensional space based on an edge of a model aligner in a ruler disc. The boundary contour may be measured on a grid in which the model aligner is formed. The information pertaining to the boundary contour in the model is transferred to a flat workpiece. The boundary contour may follow the patient's gingival margin. A trench is formed in the flat workpiece based on the boundary contour measured in the model aligner. The flat workpiece including the trench is deformed. Deforming the trench forms at least a portion of the edge of the dental aligner and may include a trim boundary. The aligner may be separated from the workpiece at the trim boundary. The model aligner and dental aligner may vacuum thermoformed from the same mold.
