Abstract: Methods and systems for generating support structures for additively manufactured objects are described herein. In some embodiments, a method includes receiving a digital representation of a dental appliance configured to implement a treatment stage of a treatment plan for a patient's teeth. The method can include generating a support structure arrangement configured to support the dental appliance during an additive manufacturing process. The support structure arrangement can be generated using a machine learning model. The machine learning model can be trained on a training data set including appliance data representing geometries of a plurality of dental appliances, support structure data representing geometries of a plurality of support structure arrangements, and outcome data representing outcomes of the additive manufacturing process for the plurality of dental appliances with the respective support structure arrangements.

Abstract: The invention relates to an arrangement of a furnace and of bulk material of glass particles, said furnace (10) comprising a pressing punch (36), a pressure, distance and/or speed sensor and a control device for controlling a pressing process based on the output signal of the sensor. The sensor detects at least a pressure, position and/or motion parameter of the pressing punch (36). The pressing punch (36) acts on the bulk material of glass particles (32)—possibly via an interposed ram (28)—, said glass particles being guided and crystallizable in a press channel (30). The trigger criterion for the process control is a change of at least a motion parameter of the pressing punch (36) upon softening of the bulk material of glass particles (32) which change is detected by the sensor.

Abstract: A mold for a dental appliance includes a dental arch portion and a beam. The dental arch portion is associated with teeth of a user. The dental arch portion includes a first distal portion, a second distal portion, and an incisor portion disposed between the first distal portion and the second distal portion. The beam extends from the first distal portion to the second distal portion. The beam includes a label portion disposed between the first distal portion and the second distal portion. The label portion forms a label for identification of the mold.

Abstract: A method for producing a cold casting mold (100) for producing dental molded parts (210) from a mixing compound (200), wherein the cold casting mold (100), having a cavity (110) that corresponds geometrically to the dental molded part (210), is additively constructed from a starting material (150) by means of a 3D printing method on the basis of a digital data set based on a three-dimensional model of the oral cavity of a patient and at least one first opening (111) that opens into the cavity (110) for filling with the mixing compound (200). The invention also relates to such an additively constructed cold casting mold (100) for a method for producing dental molded parts (210) from a sinterable or a light-curing mixing compound (200). The cold casting mold (100) is constructed having at least one second opening that opens into the cavity (110) for discharging gases and/or liquids.

Abstract: Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

Abstract: Dental restorations are created by preparing a hydrocolloid mold for such dental appliances as crowns and bridges. A slurry of zirconia powder and 3-O-acryloyl-D-glucose is prepared. The slurry is gelcast in the hydrocolloid mold with polymerization of the 3-O-acryloyl-D-glucose to a green body. The green body is dried and machined to the form of the dental restoration. The polymerized 3-O-acryloyl-D-glucose is then burned from the machined green body. The remaining zirconia body in the form of the dental restoration is then sintered to form the finished device.

Abstract: Dental devices and systems and methods for making the same are provided. In at least one embodiment, a method for fabricating an arch-shaped device for coupling to a patient's mouth is provided. The method can include adjusting a denture form device to conform to a shape and fit of a patient's mouth. The method can also include using the denture form device to obtain an impression of the patient's mouth. The method can also include selecting an arch device and adapting that arch device to conform to a model of a patient's mouth. The method can also include a denture form device that can be combined with the arch device to form a complete denture.

Abstract: A dental oven comprising a firing chamber for the heat treatment of dental restoration parts. The firing chamber is connected to a negative pressure source via a suction line. A valve arrangement is located between the firing chamber and the suction line with the aid of which the suction line is closable towards the firing chamber in order to maintain a negative pressure in the firing chamber. The suction line between the valve arrangement and the negative pressure source is ventilatable via an ambient air connection.
