摘要:
A computer-implemented method for generating a computer model of one or more teeth by receiving a digital data set of meshes representing the teeth; creating a parametric representation of the digital data set; and displaying the computer model of the teeth using the parametric representation. The model can be modified or transmitted for viewing or for fabricating dental appliances.

A computer or other digital circuitry is used to assist in the creation of a digital model of an individual component, such as a tooth or gum tissue, in a patient's dentition. The computer receives a data set that forms a three-dimensional (3D) representation of the patient's dentition, applies a test to the data set to identify data elements that represent portions of the individual component, and creates a digital model of the individual component based upon the identified data elements. Many implementations require the computer to identify data elements representing a 2D cross-section of the dentition lying in a 2D plane that is roughly parallel to or roughly perpendicular to the dentition's occlusal plane. The computer analyzes the 2D cross-section to identify dentition features that represent boundaries between individual dentition components.

Systems and methods are disclosed for generating a 3D model of an object using one or more cameras by: calibrating each camera; establishing a coordinate system and environment for the one or more cameras; registering one or more fiducials on the object; and capturing one or more images and constructing a 3D model from images.
摘要:
A system for producing corrective movement in a subject's teeth includes a dental aligner device having one or more through-holes and one or more connectors fixed to the subject's teeth. The connectors can snap into the through-holes when the dental aligner is worn on the subject's teeth.
摘要:
A method for manufacturing wrinkled dental aligner for a patient's tooth includes developing a digital dental aligner model specifying at least one wrinkled surface on a dental aligner and producing a dental aligner having the wrinkled surface in accordance with digital dental aligner model.
摘要:
A physical dental arch model includes an adjustment jig that receives a physical tooth model and enables the rotations of the physical tooth model around at least two separate axes. A base receives the adjustment jig such that the physical tooth model can rotate relative to the base around at least the two separate axes.
摘要:
A system for tracking a dental device includes a label storing a data structure comprising information about a patient's dental treatment, wherein the label is configured to be attached to the dental device and a detector configured to extract data from the data structure stored in the label to determine the shipping destination of the dental device.
摘要:
Systems and methods for producing a physical tooth model includes receiving a negative impression of a patient's tooth in a casting chamber, pouring a casting material over the negative impression of the patient's tooth, solidifying the casting material wherein the casting material is attached to the lid of the casting chamber, and cutting a tooth portion off the solidified casting material. A reference base is produced in attachment to the lid of the casting chamber. The reference base is configured to mold the physical tooth model.
摘要:
A computer obtains a digital model of a patient's dentition, including a dental model representing the patient's teeth at a set of initial positions and a gingival model representing gum tissue surrounding the teeth. The computer then derives from the digital model an expected deformation of the gum tissue as the teeth move from the initial positions to another set of positions.
摘要:
A positive mold for use in creating an orthodontic appliance is produced by obtaining a digital dentition model, such as a 3D geometric surface model or a 3D volumetric image model, that defines the shape of an orthodontic appliance and then altering the digital dentition model to remove a portion that does not affect the shape of the orthodontic appliance. The altered digital dentition model then is used to construct a positive mold for the orthodontic appliance. Processing circuitry, such as a programmed computer, is used to obtain and alter the digital dentition model. A rapid prototyping device, such as a stereolithography machine, is commonly used to construct the positive mold.
