Dental imaging and treatment system
InactiveUS20050202363A1Good precisionShort curing timeImpression capsDental toolsTooth whiteningDental structure
An intra-oral dental irradiation device for use in dental procedures for whitening teeth, imaging teeth, and making impressions of tooth structures of a patient. The device features one or a plurality of LED devices mounted to an arched shaped structure which project light upon or through teeth. In the whitening mode the light of the proper spectrum to activate enamel whitening material is projected. In the imaging mode light projected by the LED devices is received by a charged coupled device which communicates the image of the light passing through the teeth from the LED devices, to a computer. In making dental impressions, the device projects light in a spectrum that provides the catalyst to material that hardens when exposed to that spectrum thereby hardening dental impression material when inserted over the teeth of a patient.

InactiveUS20100268363A1Sufficient malleabilityCompensation for shrinkageProgramme controlComputer controlComputer Aided DesignEngineering
A dental article is fabricated from an SMC material using three-dimensional data captured from natural dentition to guide a computer-controlled milling machine. The three-dimensional data may include scans of an original tooth structure and a prepared tooth surface to characterize all surfaces of a dental article, or certain features may be created within a computer-assisted design environment taking account of occlusion, proximal contacts, and the like. In addition the model applied to a computer-controlled milling machine may account for shrinkage of the SMC material during any post-milling curing steps in order to ensure an accurate fit to the prepared tooth surface.

Orthodontic appliances having a contoured bonding surface
A quantity of a photocurable composition, such as an orthodontic adhesive containing a photoinitiator, is placed between the base of an orthodontic appliance and a replica of a patient's tooth structure. The replica is made using a material that transmits actinic radiation. As the appliance is pressed into firm contact with the replica tooth structure, an outer surface of the photocurable composition assumes the configuration of the underlying portion of the replica tooth structure. Actinic radiation is then directed to the photocurable composition, and at least part of the actinic radiation is directed through the replica tooth model in order to harden the photocurable composition. The hardened composition provides a contoured bonding surface having a shape that matches corresponding regions of the patient's tooth structure. Methods are also disclosed for making an orthodontic indirect bonding transfer apparatus for use with appliances having a contoured bonding surface.

A computer-implemented method for automated classification of 3D image data of teeth includes a computer receiving one or more of 3D image data sets where a set defines an image volume of voxels representing 3D tooth structures within the image volume associated with a 3D coordinate system. The computer pre-processes each of the data sets and provides each of the pre-processed data sets to the input of a trained deep neural network. The neural network classifies each of the voxels within a 3D image data set on the basis of a plurality of candidate tooth labels of the dentition. Classifying a 3D image data set includes generating for at least part of the voxels of the data set a candidate tooth label activation value associated with a candidate tooth label defining the likelihood that the labelled data point represents a tooth type as indicated by the candidate tooth label.
