摘要： The present invention relates to an apparatus and method for three-dimensionally laminating a ceramic denture in a color-and-transmittance variable manner. A base slurry and a light transmissive slurry are mixed at a ratio regulated by a main controller according to a slurry ratio parameter datum, and then a slurry mixture is laid on a substrate by a laying module to form a slurry layer; next, the slurry layer is photocured by a photocuring module according to a laminated graphic under control of the main controller; in such a manner, the slurry layers are laminated and cured one by one so that a denture green body is formed; finally, the denture green body is sintered at a high temperature to form a ceramic denture. The present invention allows each slurry layer to exhibit different color and transmittance, resulting in quite natural gradation of color and gradation of transmittance.

摘要： A blank for manufacturing molded dental components includes a blank body that includes tooth repairing material. A molded dental component is manufactured by removing portions of the tooth repairing material using a tool. The blank is encoded with at least one structure as a carrier of information regarding properties of the blank body. The at least one structure is arranged such that at least one of a position, dimensions, or a type of structure can be determined by sensing or measuring the blank. In this context, the position, the dimensions, or the type of the structure are embodied such that a value acquired during a determination of the above corresponds to information about a property of the blank body.

摘要： A multilayer sheet comprising first, second, and third layers is provided. The first layer consists of a co-polyester having an elongation at break of greater than 70%. The second layer consists of a thermoplastic polyurethane elastomer having an elongation at break of greater than 200% and a hardness of about 60 A to about 85 D. The first layer has a hardness greater than the hardness of the second layer. A mold is provided and the multilayer sheet is thermoformed over the mold to form a plurality of tooth-receiving cavities configured to receive and position a patient's teeth from a first arrangement toward a second arrangement. Excess material is trimmed from the thermoformed multilayer sheet to form the multilayer dental aligner.

摘要： Provided herein are orthodontic systems and methods for automatically segmenting a person's teeth. Systems, methods and processes are provided to properly segment the teeth of a person's teeth from an image of the person's face showing at least some of the person's teeth (e.g., dental arch). Methods and systems are provided to automatically detect dental edges after a dental scan. Also described herein are methods and systems for generating a simulated image of the person's face from the final segmentation of the person's teeth in which the segmented teeth have been moved from their original position, including a new position based on an orthodontic treatment plan.

摘要： A method of scanning an oral cavity including: acquiring, using an intraoral scanner (IOS) head, without changing a position of the IOS head, a first image of a first region of interest (ROI) and a second image of a second ROI where the first and the second ROIs are of different portions of a dental arch of the oral cavity and do not overlap; reconstructing depth information for the first and the second ROI; and generating a single model of the dental arch by combing the depth information.
