Disclosed is a method of manufacturing a digital overdenture to improve manufacturing convenience and preciseness. The method of manufacturing the digital overdenture according to the present invention includes a series of operations such as generating a planning image, manufacturing auxiliary devices for manufacturing the overdenture such as a surgical guide, a flattening guide, an impression model, and the like, setting a holder device and correcting a temporary denture, obtaining a corrected-scanned image, and designing and manufacturing a digital overdenture.

An assembly including a tool (1) and packaging (2) for accommodating the tool (1). The tool (1) includes at least one machining head (3) for machining a workpiece (4), in particular a dental workpiece (4), by a machining unit (5), and a clamping portion (6) for securing the tool (1) in a chuck (7) of the machining unit (5) while the workpiece (4) is being machined. The tool (1) can be repeatedly removed from and placed back in the packaging (2), with the packaging (2) being provided with at least one securing device (11) for fastening the packaging (2) in a temporary tool magazine (12) of the machining unit (5).

The present invention relates to the field of dentures. More particularly, the present invention relates to manufacturing denture teeth using fixtures to hold the teeth during a scanning, registration and milling sequence. Even more specifically, the present invention relates to using machinable wax to set denture teeth within a fixture, so that the root or crown end of the teeth may be scanned, registered with an ideal tooth model to create a milling strategy, and milled or otherwise have material removed.

A fixture plate includes a base having a contact face configured to support a dental model having a model identifier on a bottom surface. A bore extends through the base to one or more channels formed in the contact face and that extend from the bore. A viewing port extends through the base and has a transparent material inserted therein to seal the viewing port at the contact face. The viewing port and the transparent material enable the model identifier to be accessed from underneath the contact face when the dental model is on the contact face. A protrusion extends from the contact face and is configured to interface with an aperture of the dental model to retain the dental model in a specific orientation. The channels are configured to provide a suction force applied through the bore to hold the dental model against the contact face.

Dental restoration holding devices, dental restoration holding assemblies including the same, and associated methods. A dental restoration holding device includes a base portion and a cap portion, and is configured such that the base portion and/or the cap portion engages a flexible support sheet to define a support surface that supports a dental restoration relative to a suction tip. A dental restoration holding assembly for supporting a dental restoration includes the dental restoration holding device in combination with the flexible support sheet and the suction tip. A method of treating a dental restoration includes operatively engaging a flexible support sheet with a dental restoration holding device to define a support surface, placing a dental restoration upon the support surface, engaging a suction tip with the dental restoration holding device, and flowing a treatment fluid through the dental restoration holding device.

The invention relates to a denture, made of teeth, in particular prefabricated teeth, and of a denture base made of a gingival material, comprising cavities for teeth in which cavities for the teeth are mounted, in particular attached by bonding, characterized in that the denture base (12) is produced by a CAD/CAM process forming the cavities (20) for the teeth (14), and in that cervical areas (40a) of the teeth (14) extending through the basal surface (16, 18) of the denture base (12) are removed, in particular abraded or milled.
