A production system (100) for producing partial prostheses (101), with a user interface (103) for digitally designing a prosthesis framework (105) with coupling elements (119) to the residual tooth hard tissue, a prosthesis base (107) and prosthesis teeth (109).

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.

The present invention to a method of denture manufacture that incorporates CAM-formed zirconia teeth or zirconia tooth segment members, resulting in a natural fit, feel, and wear essentially equivalent to the wear properties of natural teeth, with wear and durability properties superior to dentures known in the art.

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.

The present invention to a method of denture manufacture that incorporates CAM-formed occlusal portions made of zirconia, resulting in a natural fit, feel, and wear essentially similar to the wear properties of natural teeth.

The invention relates to an assembly set for a removable partial denture comprising one or more replacement teeth as well as a framework with one or more retention sections. Each of the retention sections is configured to receive and retain one or more of the replacement teeth. Each of the replacement teeth comprises a bottom face with a surface structure configured to engage an assigned complementary retention structure provided by one of the retention sections of the framework configured to receive the respective replacement tooth. Each surface structure provides in combination with the assigned complementary retention structure a non-destructive detachable direct connection between the replacement tooth comprising the respective surface structure and the retention section comprising the respective assigned complementary retention structure.

The invention relates to an occlusion determination device (10), with a bite frame (34) and an extraoral bracket (12) which are connected together, wherein a reference element has at least one vertical leg (19, 21) and at least one horizontal leg (14, 16) and is connected by way of a bipupillar linkage (24) to the bite frame (34). The reference element is designed as an extraoral bracket (12) which extends vertically offset from the bite frame (34).

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.

A positioning feedback tool for a dental appliance takes the form of a flexible appearance strip for simulating the appearance of an installed dental appliance on a patient wearer. Dental appliances, such as dentures, rest on the gums of a wearer as functional replacements of teeth. The flexible appearance strip has visual images of dental elements (teeth) for replacing the natural teeth, and depict the size, spacing and color of the dental elements in the finished appliance. Dental elements are affixed onto a foundation mold for resembling a natural row of teeth. The foundation mold receives an imprint of the gums of the wearer, and also receives the dental elements to define the placement of the dental elements. Prior to tooth placement in the foundation mold, the flexible appearance strip is disposed against the installed foundation mold so that the patient may visualize the appearance of the finished appliance.
