The invention relates to a method for producing a dental prosthesis, wherein the dental prosthesis comprises a prosthetic base and a plurality of prosthetic teeth, wherein the method is carried out with the use of a virtual three-dimensional dental prosthesis model of the dental prosthesis which is to be produced, and wherein the virtual three-dimensional dental prosthesis model comprises virtual prosthetic teeth and a virtual prosthetic base, including the following chronological steps: A) producing a physical occlusion plate, wherein a region of the surface of the occlusion plate is formed by a negative of the coronal sides of the virtual prosthetic teeth of the virtual dental prosthesis model, wherein the location and orientation of the virtual prosthetic teeth relative to one another corresponding to the virtual dental prosthesis model remain retained in the shape of the surface of the occlusion plate; B) placing and securing preassembled prosthetic teeth on the occlusion plate, wherein the coronal sides of the pre-assembled prosthetic teeth are placed on the surface of the occlusion plate formed by the negative; C) securing the occlusion plate, with the prosthetic teeth secured therein, in a device for the layered forming of three-dimensional plastic structures; and D) printing the prosthetic base onto the basal ends of the prosthetic teeth with the device for the layered forming of three-dimensional plastic structures on the basis of the shape of the virtual prosthetic base.

The invention also relates to a dental prosthesis produced with such a method and a device for carrying out such a method.

Our method applies a continuous pressure to an exterior of a denture setup during the polymerizing and shrinking of the plastic material forming a portion of our denture. The direction from which shrinkage occurs is controlled using a constant pressure of water. Application of at least 300 pounds per square inch (psi) of water pressure during polymerization continually forces a critical inside denture surface being formed against a master model surface to allow the major shrinkage to take place on a less critical outside denture surface, thereby reducing distortion to the interior (fitted) portion of the denture. This pressure reduces the size of the air bubbles to maximize the density of the polymerized denture material, thereby lowering oral fluid sorption into our denture. Thus our denture overall is a stronger, better fitting, durable product that addresses the esthetic, health and hygiene issues presented by conventional dentures.

A two-piece anatomic dental implant with a Zirconium Dioxide base and a titanium insert. The Zirconium Dioxide base having a milled shaft into which a titanium insert is press fit retained with members to prevent rotation of the titanium insert within the Zirconium Dioxide implant. The present invention only allows metal screws from attachments to be threaded into a metal titanium insert and not threaded into a Zirconia Implant base. The invention includes an improved design for a healing cap providing minimal contact between the stronger material such as titanium and the Zirconium Dioxide.

A dental overlay device for the placement of one or more veneers in a mouth of a patient comprises a curved body. The curved body further includes a body surface and a plurality of holes. The body surface is complementary to and configured for contacting portions of one or more teeth in the mouth of a patient, including distal teeth on opposite sides of the patient's mouth, to secure the curved body in a suitable position on the patient's teeth. The plurality of holes extend through the curved body and correspond to locations on a plurality of teeth.

Dental instrumentation for use in guiding a cutting tool to remove tooth structure from a working tooth is prepared. A digital model of cutting guide shell structure for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure for guiding the cutting tool. A digital model of a fixation instrument configuration for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration for releasably fixing the dental instrumentation to the adjacent tooth and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.

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.

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 adjusting a denture form device to conform to a shape and fit of a patient's mouth. The method can also include using the denture form device to obtain an impression of the patient's mouth. The method can also include selecting an arch device and adapting that arch device to conform to a model of a patient's mouth. The method can also include a denture form device that can be combined with the arch device to form a complete denture.

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.

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. A size and geometry of each of the enlarged retention holes are determined based on a size and geometry of the corresponding manufactured tooth. 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.
