Provided is a denture base that includes a base portion; a socket that is demarcated by a step portion from a gingival area of the base portion and to which an artificial tooth is to be attached; and interdental papilla areas of the gingival area, which are positioned at both ends of the socket along a tooth row, wherein, in a state in which the socket is facing upward, a basal surface of the socket has a ridge-shaped socket apex portion configured by a surface that is convex overall, a peripheral area of the basal surface is in mutually continuous abutment with the step portion, and the socket apex portion is positioned at substantially the same height as, or higher than, apex portions of the interdental papilla areas that are seen from a labial side in a state in which the artificial tooth is attached to the socket.

Digital design and/or fabrication of a dental prosthesis that includes a gingiva part having retention pockets and corresponding injection channels that extend from the retention pockets to an exterior of the gingiva part. The positioning of a matrix mated to a ball attachment of a dental implant is fixed in the retention pocket by injection of a curable adhesive through the injection channels and into the retention pockets. The location of the retention pockets and the injection channels may be automatically generated by a computer-aided design/computer-assisted manufacturing (CAD/CAM) system. The gingiva part including the retention pockets and injection channels can further be designed and fabricated by the CAD/CAM system.

Provided is a superstructure (3) coupled to a fixture (2) that is made of pure titanium or a titanium alloy and planted in a jawbone, the superstructure (3) including: a framework (5) made of a cobalt-chromium alloy; an artificial tooth (4) bonded to the outer surface of the framework (5); and a coupling member (6) made of a gold alloy and joined to a lower part of the inside of the framework (5) to couple the framework (5) to the fixture (2), wherein the framework (5) and the coupling member (6) are integrated by being soldered together with a solder (10) composed of a gold alloy containing gold and silver.

A method of fabricating a plate denture, comprises: creating a denture plate having a concave socket formed thereon and a vertical groove formed on a bottom surface of the socket; applying an adhesive material to the socket and the vertical groove; embedding a reinforcing structure in the vertical groove to which the adhesive material is applied; and arranging an artificial tooth in the socket to which the adhesive material is applied.

The method is used for making a dental prosthesis or for the adaptation of an existing dental prosthesis for the inclusion in and attachment to existing residual dentition and/or at least one implant. Here, individual teeth and/or implants and/or the remains thereof form the anchor elements for anchoring the dental prosthesis. First, an imprint of the actual condition of the jaw of the patient occurs, from which a master model and a working model are molded. Then, the working model is adjustably fixed in a milling base and aligned with respect to the insertion direction in a milling machine or parallelometer. Next, adhesion surfaces (2) made from wax in the manner of wide-area brackets, an adhesive bridge or the like are molded onto the molded anchor elements (1). Then a molded connecting part (3) with a permanently attached parallelization pin (4) and/or retention anchor element is waxed thereon after successful alignment with the insertion direction by means of the parallelization pins (4). Subsequently either the teeth (7) forming the dental prosthesis, the cast-model framework (8) and further necessary parts are modeled in wax, or the already an existing dental prosthesis are modeled on. Finally the model is provided with injection molding passages (9), and for this purpose each of the elements is worked on individually. Then, the model is embedded and boiled out for removing the wax, and that finally after insertion of the interchangeable matrix (duplicating matrix) into the molded connecting part (3) and surface treatment of the mold inner surfaces and the plaster mold, the mold is removed, followed by the removal of the dental prosthesis.

The present invention to a method of denture manufacture that incorporates CAM-formed occlusal inserts, crowns, or overlays made of zirconia, resulting in a natural fit, feel, and wear essentially equivalent to the wear properties of natural teeth.

Systems and processes for the duplication of dentures from existing dentures. The interior and exterior of the dentures are scanned and a best fit procedure is used to create a fully digitized denture. The denture teeth are selected from a library that is the closest fit to the original denture teeth. The library teeth are offset a preset distance to compensate for the best fit. The teeth are then subtracted from the digitized denture. The margins of the denture are then cleaned after subtracting the teeth. The denture base is then ready for manufacturing. The teeth are then installed onto the denture base and provided to the patient.

A dental tray impression system, including at least one of a top denture and a bottom denture, and methods of use thereof. A top denture may include (a) a top dental impression tray including an upper trough on a palatal side and configured such that the upper trough fits adjacent to a top alveolar ridge of a patient's mouth and (b) a top tooth portion configured to removably attach to a cavity side of an anterior end of the top dental impression tray. A bottom denture may include (a) a bottom dental impression tray comprising a lower trough on a mandibular side and configured such that the lower trough fits adjacent to a bottom alveolar ridge of the patient's mouth and (b) a bottom tooth portion configured to removably attach to the cavity side of the anterior end of the bottom dental impression tray.
