Reportage in a dental prosthesis production lab which uses a system of computer-aided design and manufacturing (CAD/CAM) and is equipped with a Zirkonzahn CAD/CAM. This system allows a 3D image to be obtained from dental impression scans. From this image the digital model for the prosthesis is calculated by computer, the miller can then produce an exact copy of the prosthesis in the required material. [Photograph].

Dental bridge. Coloured frontal X-ray of a section through the jaw of a 45-year-old patient with a dental bridge (white, centre left and right). Dental bridges are fixed dental prostheses used to replace a missing tooth, or teeth, by joining the artificial tooth permanently to adjacent teeth or other implants.
Dental gold-plastic bridge in the lower jaw of a 45-year-old man. This bridge has replaced the incisors and canines, but will be replaced with a newer one. The premolars will be filed down to accommodate the new bridge. Crowns, bridges and dentures are prosthetic teeth fitted to replace missing teeth, or teeth too damaged to be repaired. For a series showing this bridge and its replacement with a new ceramic bridge, see images C030/1462 to C030/1464. For the construction of the new bridge, see images C030/1465 to C030/1468.
