A polymerisable radiation-curable composition comprising: (i) monomers, comprising at least (a) a first monomer having a TG (glass-transition point) of the homopolymer of said first monomer ?120? C. and at least (b) a second monomer having a TG (glass-transition point) of the homopolymer of the second monomer ?100? C., wherein at least one of the at least one first monomer or of the at least one second monomer has an alicyclic group, and comprising (ii) at least one further component, comprising at least one photo-initiator for the UV and/or Vis spectral region or a photo-initiator system for the UV and/or Vis spectral region. Also disclosed is a blank in the form of a three-dimensional moulded body of a polymerised composition, in particular radiation-cured composition, for producing 3D moulded bodies, dental prosthetic parts, orthopaedic appliances or dental pre-forms in a rapid prototyping, rapid manufacturing, or rapid tooling method.

A curable composite material containing nanodiamonds, denture bases and other dental prosthetics made from the composite material and methods for treating dental stomatitis using these prosthetics.

A plate denture manufacturing method includes preparing three-dimensional data for an artificial tooth impression and a plate denture, preparing a denture mold including a bottom wall, a side wall, a forming space which is surrounded by the bottom wall and the side wall and into which a denture base material is to be poured, a cutting target region to be cut by a cutting apparatus, and vent holes passing through the bottom wall, cutting a groove in the cutting target region using the cutting apparatus, placing the denture mold on a holder, placing an artificial tooth in the groove, pouring the denture base material into the forming space and curing the denture base material so as to fabricate a one-piece product including the denture mold, the artificial tooth, and a cured product of the denture base material that are integral with each other, and machining the cured product.

A curable composite material containing nanodiamonds, denture bases and other dental prosthetics made from the composite material and methods for treating dental stomatitis using these prosthetics.

A semi-finished product as a pre-product for a dental prosthesis having a prosthesis base, wherein the prosthesis base comprises at least one dental recess for receiving a set of teeth, and wherein the set of teeth is glued into the at least one dental recess by an adhesive. In the dental recess and/or in or at the set of teeth an adhesive channel is configured which extends along the at least one dental recess or the dental arch in its main direction of extension. It starts at an adhesive filling opening whose configuration is adapted to a filling element.

A dental prosthesis having a prosthesis base and a set of teeth, namely a full set of teeth or a partial set of teeth, is provided, wherein the prosthesis base comprises at least one dental recess for receiving the set of teeth, and wherein the set of teeth is glued into the at least one dental recess by an adhesive. In the dental recess and/or in or at the set of teeth an adhesive channel is configured which extends along the at least one dental recess or the dental arch in its main direction of extension. It starts at an adhesive filling opening whose configuration is adapted to a filling element.

A method of fabricating a denture, comprising milling a preliminary try-in denture from denture material comprising a layer of denture base material contiguous with a layer of denture tooth material. Denture base material is removed from the block to form a first part of the, labial, buccal, gingival, and flange regions of the denture base to form a preliminary denture. A preliminary mold is created from this preliminary denture. The preliminary denture is then further modified with deformable waxes in gingival and anterior tooth recesses to form a preliminary try-in denture, which is fitted to a patient and adjusted to optimal dimensions. The adjusted try-in denture is then reproduced by further molding methods, producing the final denture.

This invention designs and builds multiple layers (two layers or more) of millable dental blocks or disks for milling of various dental devices, specifically denture base blocks or disks of denture base material, where milled teeth cavities to receive artificial denture tooth materials to form final dental devices, such as partial and full dentures. This invention also designs and builds multiple layers (two layers or more) of millable denture base or denture blocks or disks comprised of denture base or/and denture tooth materials to form final dental devices, such as partial and full dentures. A method for manufacturing a layered denture is provided. The invention provides a multiple layered denture base block (or disk) for milling a denture base. The invention also provides a multiple layered denture block (or disk) for milling a denture. Highly shape adjustable or shape memory polymer layer(s) may be used in these multiple layered forms. Different layer of material has different mechanical and physical properties to meet different need, which provide added benefits to the patients, dental professional and dental laboratory.

A custom oral device is provided that fits on the maxillary or mandibular arch of a wearer. The oral device comprises a tray that corresponds with the shape and size of a wearer's oral anatomy. A soft liner is disposed within an occlusal channel of the tray having an upper surface that comprises an impression having features that correspond to at least a portion of the wearer's dentition and in which the wearer's teeth align. An apparatus and a method for making the custom oral device are provided.

Disclosed is a method for manufacturing a dental prosthesis, including a step of digitally designing a dental prosthesis model from a replica model of a patient's teeth, a step of generating a jaw portion model including the teeth replica model and the dental prosthesis model, a step of manufacturing a jaw portion including a positioning member based on the model of the jaw portion, and a step of positioning the jaw portion on a shell of a shell mold by the interaction of the positioning member of the jaw portion with a complementary positioning member arranged in the shell. Also disclosed is a shell mold used in such a method.
