A method of creating a reinforced dental prosthesis is provided that can include providing a three-dimensional (3D) printed dental prosthesis, and applying a coating solution to at least a portion of an outer surface of the 3D printed dental prosthesis. The coating solution can include a polymerizable resin and filler particles distributed within the polymerizable resin. The method can include curing the coating solution on the 3D printed dental prosthesis to create the reinforced dental prosthesis.

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.

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.

An improved method of a dental framework design and manufacturing, incorporating a dental framework design volume to eliminate framework or denture teeth modification post framework manufacturing.

A method for designing dentures according to which artificial teeth can be easily and accurately attached to a denture base, which is designed and shaped by CAD/CAM, when the artificial teeth are arranged on the denture base is provided. The method for designing a denture (10) on a computer based on data on an intraoral shape comprises: creating data on a shape of a denture base (20) based on the intraoral shape (S22); creating data on a position of an artificial tooth (30) to be arranged on the denture base (S23); and creating data on a shape of an occlusal guide (40) that is tabular and has a recess part corresponding to a shape of the arranged artificial tooth in an occlusal surface side (S24).

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.

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 method for designing dentures according to which artificial teeth can be easily and accurately attached to a denture base, which is designed and shaped by CAD/CAM, when the artificial teeth are arranged on the denture base is provided. The method for designing a denture (10) on a computer based on data on an intraoral shape comprises: creating data on a shape of a denture base (20) based on the intraoral shape (S22); creating data on a position of an artificial tooth (30) to be arranged on the denture base (S23); and creating data on a shape of an occlusal guide (40) that is tabular and has a recess part corresponding to a shape of the arranged artificial tooth in an occlusal surface side (S24).

A method including modifying a known upper denture to form a final upper denture by a series of steps which may include making holes in a gums section made of a first material of the known upper denture, cutting away a palate section, and applying a gold and silicon mixture to make a new palate section, to insert into the holes in the gums section, and to cover the first material. The method may also include modifying a known lower denture to form a final lower denture by a series of steps which may include making holes in a gums section made of a first material of the known lower denture, and applying a gold and silicon mixture to insert into the holes, and to cover the first material. The first material may be nylon.

A blank for producing dental prostheses by particularly material-removing processing comprises a tooth element and a jaw element. These elements are preferably differently colored layers of a blank produced from the same material. In order to cover a dividing line between the differently colored regions, a gum element is arranged especially in a recess of the finished dental prosthesis.
