The invention relates to a prosthesis base, which is made entirely or partially of a prosthesis material and/or wax and has on its top face at least one substantially custom-fit recess (3) for zonally receiving an artificial tooth (1). According to the invention at least one channel (5) is formed in the prosthesis base (2), which opens into said recess (3).

Furthermore, the invention relates to a process for the substance-to-substance bond of an artificial tooth (1) to a prosthesis base (2), which is made entirely or partially of a prosthesis material and/or wax and has at least one substantially custom-fit recess (3) for zonally receiving said artificial tooth (1).

A manufacturing method for a prosthetic apparatus for dental purpose according to one aspect of the present invention includes: acquiring scan data of a model that is a reproduction of at least a part of an inside of an oral cavity of a patient; creating shape data of a shaped body for dental purpose on a basis of the scan data; producing a shaped body on a basis of the shape data; covering at least a part of the shaped body and at least a part of a model with film, the shaped body attached to the model; releasing air in a part covered with the film to deform the film and bring the shaped body into close contact with the model; and curing the shaped body in a state where the shaped body is in close contact with the model.

A system including a method and associated structures creates efficiencies in the manufacture of prosthetic tooth support frameworks. Pre-manufactured teeth with matching internal keys are used in the setup of a patient prototype. Each key includes a shaft, a cervical platform, a retention knob and preferably at least one channel for the expulsion of excess adhesive fluid. The cervical platforms are shaped to provide intimate contact with a base of their respective tooth. The same tooth/key pairs are then used to make a framework pattern from the setup positioning. The pattern can be cast or scanned for direct machining to produce the finished framework.

A method for creating a digital model of a denture for a patient, where the denture includes a gingival part and artificial teeth, includes obtaining digital models of artificial teeth representing the artificial teeth; obtaining a 3D scan comprising a digital representation of at least part of the patient's existing gingiva; digitally modeling a gingival part of the digital model of the denture using the 3D scan and the digital artificial teeth; digitally determining a first offset defining a first thickness of a first portion of the gingival part of the digital model of the denture that extends from the digital representation of the at least part of the patient's existing gingiva; and digitally determining a second offset defining a second thickness of a second portion of the gingival part of the digital model of the denture that extends from the digital artificial teeth.

Disclosed is a method for modeling and manufacturing a denture for a patient, where the denture comprises a gingival part and artificial teeth, wherein the method comprises: providing a 3D scan comprising at least part of the patient's oral cavity; virtually modeling at least part of the denture using the 3D scan; obtaining virtual teeth to represent the artificial teeth; virtually modeling at least one of the virtual teeth to obtain a set of modeled virtual teeth; manufacturing the modeled virtual teeth in a first material; manufacturing the gingival part in a second material; and manufacturing at least part of the denture by means of computer aided manufacturing (CAM).

A dental prosthetic positioning assembly comprises an occlusal assembly and a maxillary arch subassembly. The occlusal assembly includes a maxillary tray configured to be formed in a patient's maxillary alveolar ridge, wherein the maxillary tray comprises a occlusal rim component. The occlusal assembly further includes a carriage frame component composed of biocompatible magnetic metal material anchored to the maxillary tray. The maxillary arch subassembly comprises a plurality of prosthetic maxillary teeth components magnetically anchored to the occlusal rim component. The carriage frame component is moveable with respect to the maxillary tray. The prosthetic maxillary teeth components are individually moveable with respect to each other to achieve a desired dental positioning.

A removable dentures device includes a denture base, a denture framework, at least one buffer element and at least one denture crown assembly. The denture framework is provided on the denture base. The buffer element includes buffer body and cutting groove. The buffer body is provided on the framework, and the cutting groove is formed on a side surface of the buffer body. The denture crown assembly includes denture crown body and accommodation groove, and the accommodation groove is formed on the bottom of the denture crown body. The buffer body is provided inside the accommodation groove. In addition, a removable dentures device assembly method is also proposed.
