A reference member for determining a position of an implant analog can comprise a trapezoidal body including a first side and a substantially parallel second side. The first side can define a first dimension and the second side can define a second dimension that is greater than the first dimension.

The invention relates to additively manufactured dental devices comprised of a denture base and at least one removable bracing body joined at specific locations to the denture base. The invention also relates to methods of using these additively manufactured dental devices in the fabrication of dental prostheses.

The invention relates to a method for processing prosthetic teeth for the production of a full denture or at least a partial denture with at least two prosthetic teeth with the following steps: at least two prefabricated prosthetic teeth are inserted with their coronal sides into recesses an elastic mold, a clamping device is attached to the elastic mold, and after insertion of the prosthetic teeth into the elastic mold a mechanical pressure is applied to the elastic mold with the clamping device, wherein the pressure exerts a force onto the prosthetic teeth inserted into the elastic mold via the elastic mold and thus the prosthetic teeth are affixed in the elastic mold, the prosthetic teeth are positioned and aligned in the elastic mold in such a manner in relation to each other that at the latest following application of the clamping device on the elastic mold, the prosthetic teeth comprise the desired position and desired alignment in relation to each other, the elastic mold is affixed with the clamping device and prosthetic teeth in a defined position in a holder of a CAM device for removing material of the prosthetic teeth with a CAM method, and at least one of the prosthetic teeth affixed in the elastic mold is basally ablated with a CAM method.

The invention further relates to a device for holding prosthetic teeth for the implementation of such a method and a set for the implementation of such a method with such a device.

Methods for manufacturing a denture including providing a cavity having a plurality of wells formed therein for receiving denture teeth, inserting denture teeth into the wells so that distal coronal aspects face into the wells, positioning the cavity over a core to form a molding void therebetween, in which the exposed proximal aspects of the denture teeth are in the molding void, and introducing a molding material into the molding void to envelope the proximal aspects of the denture teeth and form a denture base upon at least partial setting of the molding material. Once set, the denture base with denture teeth retained therein may be removed from the cavity and core. Using such methods, a kit of differently sized prefabricated dentures in which the denture bases comprise a plastically deformable material may be provided, an appropriate denture selected, and semi-customized to a patient.

An object is to provide an artificial tooth that can be attached to a denture base designed by CAD/CAM to be formed easily and accurately when the artificial tooth is arranged on the denture base.

In an artificial tooth (21) that has a shape corresponding to a denture base that is designed on CAD based on three-dimensional data and is cut out, a regulator (21a to 21h) that regulates the rotation on the axis of the tooth as the center is provided for a portion to touch the denture base, and the regulator has a shape so as not to engage with the denture base in the direction of the axis of the tooth.

The invention relates to additively manufactured dental devices comprised of a denture base and at least one removable bracing body joined at specific locations to the denture base. The invention also relates to methods of using these additively manufactured dental devices in the fabrication of dental prostheses.

The present invention relates to a method of producing a dental object (100), comprising the step of producing a support structure (101) on the dental object (100) having a predetermined breaking point (103) arranged such that a residual portion (105) of the support structure (101) remains on the dental object (100) after the predetermined breaking point (103) is separated.

Systems and methods for securing artificial teeth to a dental prosthetic base with a gradient polymer are disclosed herein. An example system includes one or more processors and a memory communicatively coupled with a 3D printing device and the one or more processors. The memory stores a set of instructions thereon that, when executed by the one or more processors, cause the one or more processors to: generate a print file representative of a polymeric dental prosthesis, the print file including (i) a first material, (ii) a second material that does not chemically bond with the first material, and (iii) a gradient transition zone bonding the first material to the second material that is a gradient polymer of the first material and the second material; and print, via the 3D printing device, the polymeric dental prosthesis based on the print file.

The invention relates to a bonding auxiliary device (100) for arranging, aligning and fixing a plurality of artificial teeth (210) to be bonded into an artificial gingiva (220) of a dental prosthesis (200), the bonding auxiliary device (100) comprising: an occlusion device (110) for arranging and aligning the teeth (210) relative to one another, a support device (120) for supporting a prosthetic body (221) of the first dental prosthesis (200) comprising the gingiva (220), and a clamping element (140) for fixing the teeth (210), which are arranged and aligned by means of the occlusion device (110), in the gingiva (220) supported by the support device (120).
