An anatomical healing abutment is configured to connect to a dental implant. The healing abutment has a body portion which includes at least three reference marks that provide data to orient the connection axis of the abutment with the that of the dental implant so that certain conventional steps, including healing abutment manipulation, multiple scans, and the taking of impressions, can be eliminated, thereby saving time and effort on the part of the practitioner.

A dental treatment appliance transmits a pulsed light signal towards the oral cavity and captures images of the oral cavity from light returned from the oral cavity. A controller actuates the treatment of the oral cavity of the user depending on the captured images.

A method of multimodal scanning may include generating surface scan data of an intraoral structured using structured light. The method may include generating volumetric scan data of an internal structure of the intraoral structure with OCT scanning. The OCT scan data may be aligned with the surface scan data. A three-dimensional volumetric model of the patient's dentition may be generated based on the aligned OCT scan data and the surface scan data.

The present invention relates to methods and systems for generating a 3-D dental impression with a corresponding hinge axis position and, in certain embodiments, a condylar guide inclination. In some embodiments, an intraoral scanner and a computer processing system are employed to: i) generate upper and lower jaw models, and first and second occlusal 3-D models with different mouth openings (MOs) or functional positions (FPs), ii) align the models to generate a composite 3-D model, iii) calculate a hinge axis position from the composite 3-D model based on the difference in said MOs or FPs, and iv) mount the 3-D dental impression on a virtual articulator (VA) by aligning the hinge axis position to the hinge axis position of the VA.

In a system of manufacturing an orthodontic wire, a method for manufacturing the orthodontic wire using the system, and an orthodontic wire bending machine for performing the system, the system includes a teeth data obtaining part, a simulating part, a calculating part and a wire manufacturing part. The teeth data obtaining part obtains present teeth data of a patient. The simulating part generates final teeth data. The calculating part compares a predetermined threshold to a compared value between the present teeth data of the patient and the final teeth data. The wire manufacturing part selectively manufactures a wire for an orthodontic process or a wire for a dentition maintenance process based on a compared result of the calculating part.

A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

Systems and methods for automating the production of dental aligners is disclosed. In some embodiments the systems and methods include a three-dimensional printer in communication with one or more computer and one or more computer programs. The system and method configured to permit persons to automatically scan and upload a pre-existing digital scan, x-ray, physical mold or other impression of a person's teeth to the three-dimensional printer for direct real-time printing of custom dental aligners. In some embodiments, the system and method also includes an intraoral scanner configured to permit persons to take and receive a real-time digital scan of their teeth and receive a real-time custom dental aligner, on the same day and from the same integrated system, method, machine, kiosk and location.

A method for correcting a geometric distortion in a diagnostic image, said method comprising the steps of: receiving a segmented volumetric image and a surface scan image, corresponding to a maxillofacial anatomy of a patient; aligning the surface scan mesh to a volumetric image; and applying a transformation to the surface scan image mesh in which the geometry of a HV-LD is altered yielding the surface scan image mesh with tooth crowns closely corresponding to the volumetric image teeth image resulting in a correction for the geometric distortion.

A data processing apparatus for processing three-dimensional data including a position of each point of a point group representing at least a surface of an object, the three-dimensional data being acquired by a three-dimensional scanner, the data processing apparatus, including a scanner interface to which the three-dimensional data acquired by the three-dimensional scanner is input; and processing circuitry configured to generate a data set by using a plurality of pieces of the three-dimensional data located in a predetermined range among a plurality of pieces of the three-dimensional data input from the scanner interface, and, set, when a plurality of data sets are generated, a data set with a largest data amount or at least a predetermined data amount as a true data set among the plurality of data sets.

The data processing apparatus includes a scanner interface to which three-dimensional data acquired by the three-dimensional scanner is inputted, and processing circuitry configured to verify first three-dimensional data input from the scanner interface and second three-dimensional data input from the scanner interface by comparing the first three-dimensional data and the second three-dimensional data in a virtual space set with respect to the position of the three-dimensional scanner.
