A dental prosthesis is provided, manufactured from a monobloc or multibloc prosthesis blank (10), which is composed of a gum-colored material (14) and a tooth-colored material (12), which materials (12, 14) are bonded to each other by bonding, polymerization and/or one-piece manufacture. The boundary surface (16) between the materials is wave-shaped comprising alternating grooves (22) and ribs (24) in the course of the dental arch, and radial in an oral-vestibular direction in the region of the anterior teeth (33) to be created. The boundary surface (16), at least in the region of the molars (26)again as viewed in the oral vestibular directionhas parallel grooves (22) and ribs (24) forming troughs and crests of the waveform, or grooves (22) and ribs (24) such that they extend in deviation from parallel by at most 10 degrees, in particular at most 5 degrees, at least in the region of the molars (26).

The invention relates to a method for the production of a dental prosthetic moulded part, such as a partial or total prosthesis, which is produced in a multilayered manner from a generatively produced solid body model of at least one prosthetic tooth or of a prosthetic dental arch, wherein, inside, tooth neck-sided, the prosthetic teeth have a lumen, in which a dentin-hued, polymerisable composition is filled. The composition is subsequently polymerised in at least one step. The at least one prosthetic tooth with dentin-hued composition is arranged, with its cervical side, on the tooth-sided surface of the denture base and compacted. Subsequently, the partial or total prosthesis obtained is completely cured in a light curing device. The prosthetic moulded parts obtainable according to the method according to the invention are also a subject matter of the invention.

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 disposing each of a plurality of teeth into respective teeth receptors of an inlay device, positioning the inlay device in a recess of a lower portion of a mold device, and coupling the lower portion to an upper portion of the mold device to sandwich the inlay device therebetween. The method can also include injecting a base compound into an injection hole of the mold device, and processing the base compound to integrate the base compound with the plurality of teeth.

The invention relates to a method for producing a wax base or a prosthesis base for producing a dental prosthesis, with which a virtual CAD model of the dental prosthesis is used for the production of the physical dental prosthesis or the physical prosthesis base, wherein, from the CAD model of the dental prosthesis, a virtual model of the prosthesis base is calculated, characterized by the following chronological steps: A) Scanning in of at least one three-dimensional region of a physical model of the oral cavity situation of a patient and preparation of a first data record on the basis of this scan, or intra-oral scan of a three-dimensional region of the oral cavity situation of the patient and production of a physical model of the oral cavity situation of a patient on the basis of the intra-oral scan and preparation of a first data record on the basis of the intra-oral scan; B) application of a wax layer or a plastic layer onto the physical model of the oral cavity situation; D) calculation of a virtual surface as a surface which is to be formed in the wax layer or in the plastic layer, wherein the calculation is made on the basis of the virtual model of the prosthesis base and of the first data record, and wherein positioning aids are provided in the surface which is to be produced, for the positioning of prosthetic teeth; and E) production of the wax base from the wax layer or of the prosthesis base from the plastic layer with a subtractive CAM method, on the basis of the virtual surface calculated in step D).

The invention also relates to a method for producing a dental prosthesis or a wax set-up for a dental prosthesis, and a prosthesis base, a wax base, or a dental prosthesis, produced with such a method.

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.

Preparation of a dental prosthesis that includes a gingiva part having retention holes for seating of manufactured teeth, with the retention holes being enlarged relative to the manufactured teeth. Wax in the enlarged retention holes permits adjustments in positioning of the manufactured teeth, and a helper structure preserves this positioning when the wax is removed and a curable gingiva material is filled into the retention holes. Aspects described herein include digital and/or automatic design of the dental prosthesis and its constituent pieces, as well as automated fabrication thereof in whole or in part, such as in a dental CAD/CAM system.

The present invention provides a photocurable composition which is used for the production by stereolithography of a dental prosthesis or the like. This photocurable composition contains a (meth)acrylic monomer component and a photopolymerization initiator; and the (meth)acrylic monomer component contains: an acrylic monomer (X) containing, within one molecule, two aromatic rings and two acryloyloxy groups, and having a Mw of from 400 to 580; and at least one of: a (meth)acrylic monomer (A) containing, within one molecule, one or more ether bonds and two (meth)acryloyloxy groups, and having a Mw of from 200 to 400; a (meth)acrylic monomer (B) not containing, within one molecule, a ring structure other than an aromatic ring and one (meth)acryloyloxy group, and having a Mw of from 130 to 240; or a (meth)acrylic monomer (C) containing, within one molecule, a hydrocarbon skeleton and two (meth)acryloyloxy groups, and having a Mw of from 190 to 280.

A layered denture having at least one of an integrated layer, balanced occlusion, and a root approximating structure is disclosed. The resulting denture may be suitable for use without an underlying reinforcement bar and may provide enhanced aesthetics by approximating natural dentition and roots both above and below the gum line.

By using key structures which allow an unambiguous relative positioning, it is possible to produce mold blanks consisting of several layers, from which molded bodies can be produced by machining in an automated manner. These bodies may not only have an irregular but predefined shape, but they also have at least one irregular but predefined parting surface between two layers, the positioning on this parting surface relative to the surface being predefined.
