Provided is a method for generating an orthodontic teeth alignment shape for an orthodontic treatment, the method including the steps of: extracting specific points from a plurality of teeth in at least one of the upper and lower jaws, based on a patient's teeth shape information; generating a three-dimensional patient arch form based on the extracted specific points; comparing the patient arch form with a plurality of standard arch forms to select the standard arch form most similar to the patient arch form from the plurality of standard arch forms; and generating the orthodontic teeth alignment shape based on the selected standard arch form.

A composite, three-dimensionally stable facing material for adding aesthetic features to a denture base. The composite may be a flexible, flat strip of material capable of being molded to gingival surfaces of the denture base and retained on the denture base. The strip is capable of being trimmed and then cured to a hardened state. Fibers and/or other characterization may be added for increasing realism of the denture gingival surfaces.

A tooth model for dental treatment practice is composed of a transparent material and includes a root canal in which a hollow neural tube is formed and a crown formed on top of the root canal, wherein a coating layer is formed inside the neural tube by applying a paint based on an opaque material to an inner surface of the neural tube, so as to show the neural tube formed inside the root canal to the outside.

A system includes an orientation determination system comprising a camera where the camera is configured to capture an image of an orientation feature of a physical dental model of a dental arch of a customer with material thermoformed thereon. The orientation determination system is configured to identify an offset of the physical dental model with respect to a fixture plate during positioning or before or after the physical dental model is positioned on the fixture plate by determining an actual orientation of the physical dental model based on the orientation feature. The system also includes a laser trimming system configured to cut the material along a trim line based on the identified offset while the fixture plate is moved about at least two axes to produce a dental aligner specific to the customer and being configured to reposition one or more teeth of the customer.

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.

Methods for generating multiple orthodontic treatment options for a digital 3D model of teeth in malocclusion. The method generates a plurality of different orthodontic treatment plans for the teeth and displays in a user interface the digital 3D model of teeth in malocclusion with a visual indication of each of the plurality of different orthodontic treatment plans. The visual indication of the treatment plans can be overlaid on the digital 3D model of teeth in malocclusion and possibly include aligners, brackets, or a combination of aligners and brackets. A doctor, technician, or other user can then select one of the treatment plans for a particular patient.
