The invention relates to a server for sending and receiving data, in particular for an order control of production orders, wherein the server is adapted to establish a data connection with a plurality of order computers arranged distanced from the server at an orderer location and to receive an order data package containing geometric anatomy information, in particular about a digital dental impression of a patient and address information about the order computer, from each one of these order computers.

A dental appliance having an integrally formed reservoir and/or an ornamental design integrated thereon. The ornamental design can be selected or customized by a patient. The design can be created by directing energy to the dental appliance to alter a material property of at least a portion of the appliance to create the design. Alternatively, a groove or recess can be formed on a surface of the appliance to either mechanically retain an ornamental design or the groove or recess can be filled with ink to form the design. The appliance, including the integrally formed reservoir, can be formed using direct fabrication techniques.

A method of manufacturing an article comprising: (a) performing an additive manufacturing process to firm an article in an initial state, the article comprising mounting features and being supported during the additive manufacturing process by support structures; and (b) performing a second manufacturing process to transform the article into a second state, which second manufacturing process is a subtractive process comprising: (i) mounting, via the mounting features formed during the additive manufacturing process, the article in a holding device of a machine for operating on the article, with the support structures or at least remnants thereof remaining on the article, and (ii) with the article so mounted in the holding device, processing at least one feature on a surface of the article on which the support structures were provided to remove material on the at least one feature provided by the support structures.

Disclosed herein are methods of manufacturing an oral appliance, the method comprising the steps of: a) importing into a computer aided design (CAD) computer program a digitized data set obtained from a three-dimensional scan of a patient's dentition; b) preparing a three-dimensional electronic model of the patient's dentition; c) subtracting the three-dimensional electronic model of the patient's dentition from an image of a solid block to obtain an appliance data set; and d) manufacturing a dental appliance in accordance with the appliance data set. Also disclosed are devices made by the above method, and methods of treating a condition, for example a sleep breathing disorder, by using a device made by the above method.

A radiation curable composition including at least one radiation hardenable component, a photo-initiator, and a filler material having a population of particulates in an amount greater than or equal to 50% by weight of the printable composition. The population of particulates exhibits a median diameter (D50) of greater than or equal to 0.3 micrometer on a volume-average basis as determined using the Particle Size Test Method, and the radiation curable composition exhibits a viscosity of less than or equal to 150 Pa s when measured using the Viscosity Test Method. A method, apparatus, and systems for producing composite articles by selectively exposing a portion of the radiation curable composition to a source of actinic radiation to at least partially cure the exposed portion of the radiation curable composition, thereby forming a hardened layer, preferably by an additive manufacturing process such as stereophotolithography, are also described. The composite articles may include composite dental restorations.

The present invention relates to implantable medical devices (dental and orthopedic) (osseointegrable implants) textured by the additive manufacturing process. Such implants are prepared in such a way as to comprise a larger surface area of contact between implant/adjacent tissues, porous microstructure with complex geometry with controlled and diversified pore size, which confers several technical advantages. In addition, the present invention relates to the process of preparing said implants and/or screws with an optimized structure for accelerating osseointegration. Finally, the present invention refers to the use of said implants as carriers of drugs or cells in order to treat the site, promote its healing, tissue regeneration or promote cell growth.

The present invention relates to a polymerizable composition, which comprises (a) at least one radically polymerizable compound and (b) at least one initiator for the radical polymerization, wherein the composition furthermore comprises (c) at least one UV absorber and (d) at least one optical brightener and comprises at least one radically polymerizable oligomer and at least one radically polymerizable, polyfunctional monomer as the at least one radically polymerizable compound (a).

A method of obtaining three-dimensional data includes: obtaining three-dimensional reference data with respect to an object; aligning, on the three-dimensional reference data, a first frame obtained by scanning a first region of the object; aligning, on the three-dimensional reference data, a second frame obtained by scanning a second region of the object, at least a portion of the second region overlapping the first region; and obtaining the three-dimensional data by merging the first frame with the second frame based on an overlapping portion between the first region and the second region.

A method for producing a dental adaptive element for alleviating recession of gingiva around an alveolar socket of a patient includes: obtaining images of a tooth; creating a 3D model having a crown part and a root part based on the images; obtaining a boundary curve on the 3D model between the crown part and the root part; on the root part of the 3D virtual model, obtaining an imaginary surface that protrudes in a direction from the crown part toward the root part; extracting a sub-model from the 3D model by removing a portion of the root part that extends between the imaginary surface and an end of the root part; and producing a dental adaptive element according to the sub-model.

A real-time monitoring system for an artificial tooth processing machine includes a work bed portion on which a base tooth material selected from a titanium material and a zirconia material is fixedly installed and in which a wet die configured to process a titanium material and a dry die configured to process a zirconia material are disposed to be comparted from each other, a processing tool portion having one end on which a driving spindle to which a processing tool is coupled is provided to process the base tooth material while approaching or moving away from the base tooth material, and a spindle monitoring portion provided on the driving spindle, disposed in the work bed portion, and configured to monitor the driving spindle to recognize an abrasion degree, a damage state, alignment, or the like of the processing tool in real time.
