Provided herein is a method of making a flexible partial denture, which may include: (a) producing a partial denture base by additive manufacturing (e.g., bottom-up or top-down stereolithography) from a dual cure resin, with the dual cure resin comprising a light polymerizable component and a heat polymerizable component, with the denture base including at least one tooth socket; (b) inserting an acrylic artificial tooth into each at least one tooth socket to produce an assembled intermediate product; and then (c) baking said assembled intermediate product for a time sufficient to cure said heat polymerizable component in said denture base and retained dual cure resin, bond said tooth into each at least one socket with said retained dual cure resin, and produce said flexible partial denture. A flexible partial denture produced and resin formulations useful for the same are also provided.

A dental model and related systems and methods, including a first component representing a portion of a patient's jaw and a second component that is demountably attachable to the first component, and a second component representing a dental structure of interest, such as the remaining portion of a tooth or a dental implant.

Method for producing a mockup of a patient's dental cosmetic restoration, characterized in that it comprises a step (E4) of forming a file of digital data representing the dental mockup artificially presenting the restoration intended to be placed in the mouth and worn temporarily over at least part of the patient's dentition, and a step (E5) of fabricating the mockup directly from the file of digital data produced.

A device for progressively building up an object from a light hardenable material. The device has a perforated build platform for the object. The build platform forms a build surface that faces a light source. The build platform and the light source are positionable relative to each other by computer control. The device is further configured for supplying the light hardenable material through the perforation of the build platform for building up the object. The invention enables the making of colored objects by stereolithography.

The present invention relates to a computer implemented method for modifying a digital three-dimensional model (3) of a dentition comprising: displaying an image of the dentition by applying a virtual camera to the three-dimensional model to render the image for a display (1); acquiring a line drawn by a user on the image on the display (1); projecting the acquired line, using the virtual camera (4), to a three-dimensional projection surface (7) approximating the shape of the dental arches and extending the upper and lower dental arches to cover any opening therebetween; obtaining visible teeth arch contour curves, namely incisal curve and gingiva border curve, of the upper and lower teeth arches, and projecting the teeth arch contour curves to the projection surface; selecting one of the teeth arch contour curves as teeth arch contour curve to be modified and selecting the other teeth arch contour curve of the same teeth arch or a curve derived therefrom as a baseline curve; deforming all teeth belonging to the selected contour curve to be modified along the projected line in the three-dimensional model of the dentition in a length direction such that at least parts of the selected contour curve to be modified, after deformation and projection to the projection surface, coincide with the projected line and any remaining parts of the selected contour curve to be modified are located between the projected line and the baseline curve, whereas the baseline curve remains unaffected by the deformation.

Provided are compositions and devices containing microspheres encapsulating one or more drug(s). The compositions and devices may be used to treat or prevent infection associated or caused by oral mucosal diseases, oral infections, oral conditions, dental conditions, or surgical recovery. The devices include, but are not limited to, splints, mouth guards, full dentures, partial dentures, or fillings. The devices may be manufactured from filaments that have a composition of the present disclosure. Also provided are methods of making and using the devices and compositions.

A method for producing molded parts from a sinterable mixing compound using a cold casting mold having a cavity that corresponds geometrically to the molded part and at least one opening into the cavity, wherein the mold is additively constructed from a starting material, in particular a 3D printing method using a 3D printer, and wherein the cavity is created on the basis of a digital data set, in particular based on a three-dimensional model of the oral cavity of a patient. The cavity is filled via the opening with the sinterable mixing compound, curing and/or solidifying the mixing compound, wherein gases and/or liquids contained in the mixing compound are discharged from the cavity via the opening, thermally and/or thermochemically decomposing the mold at a temperature from 200° C. to 2500° C. and sintering the mixing compound to hardness at a temperature from 900° C. to 2500° C. until a molded part is obtained.

Processes and systems for creating digital designs of patient specific dental appliances and parts thereof, such as dental bands and wires. After receiving an order for a dental appliance that includes data regarding the patient's teeth and optionally adjacent anatomy, the digital design of the dental appliance is automatically started by dental appliance design software using rules based logic. Thereafter, a human can continue, and in some embodiments complete, the digital design. Or the entire design can be completed by the dental appliance design software without any human intervention. The final digital design can then be used to create the patient specific dental appliance.

The invention relates to the use of a printing sol as construction material in an additive manufacturing process for producing a 3-dim article, the printing sol comprising solvent(s), nano-sized crystalline zirconia particles in an amount from 2 to 25 vol.-% with respect to the volume of the sol, the average primary particle size of the nano-sized crystalline zirconia particles being in a range up to 50 nm, a first monomer being a polymerizable surface modification agent represented by formula A-B, with A being capable of attaching to the surface of the nano-sized crystalline zirconia particles and B being a radiation curable group, optionally a second monomer, the second monomer comprising at least one radiation curable moiety but no acidic or silane group(s), photo initiator(s). The invention also relates to a ceramic article obtainable according to such a process.

A system and method of producing dental appliances is provided. The system includes a 3D printer system and one or more additional additive manufacturing systems. The additional additive manufacturing systems are designed to add one or more layers of materials to dental appliances printed using the 3D printer system. By adding the layers of materials to the 3D printed appliance, the physical and mechanical properties of the 3D printed appliance are modified as required.
