| 摘要 |
The invention relates to a dental prosthesis production device in which the dental prosthesis has an implant (40) and an abutment (10) which has a shape that is compatible with the implant (40) and on or to which abutment a dental structure (28) that is made of a dental material, in particular ceramic and/or plastic, and produced with the aid of a CAM process using rapid prototyping or compression molding technology can be secured. The abutment is mounted on the implant (40) via a releasable connection, in particular a screw connection (44), having an anti-rotation mechanism (50), and an anti-rotation device (groove 22) is formed between the abutment (10) and the dental structure (28). A selection device (66) is provided for abutments, said selection device allowing a selection of the abutment (10) for producing the dental prosthesis, optionally after reducing the abutment height to a specified value in a patient-specific manner, and a machining tool, in particular a milling cutter, or a CAM device is provided for shortening the abutment (10). |

1. A dental prosthesis production device, comprising:
an implant (40) and an abutment (10) which has a shape that is compatible with the implant (40) onto which abutment a dental structure (28) which is produced by means of a CAM process, using rapid prototyping or compression molding technology and which is made of a dental material, can be attached, wherein the abutment is mounted on the implant (40) via a releasable connection, having an anti-rotation mechanism (50), and an anti-rotation device (groove 22) being configured between the abutment (10) and the dental structure (28), characterized in that the anti-rotation device forms at least one flute (groove 22) at a cylindrical or conical area of the abutment (10) (4, 14, 22) which flute extends across at least a part of the height of this area, the flute ending at an end radius or at an end slant of the abutment (10) (5, 15, 21) which flute(s) is/are maintained true to shape even if the area is shortened, and that a selection device (66) is provided for abutments, said selection device allowing a selection of the abutment (10) for producing the dental prosthesis, optionally after reducing the abutment height to a specified value in a patient-specific manner, and a machining tool, or a CAM device is provided for shortening the abutment (10). |
