Dental CAM System

In dentistry, the major developments of dental CAD/CAM systems occurred in the 1980s. Actually there was three pioneers who contributed to the development of the current dental CAD/CAM systems; Dr. Duret, Dr. Mörmann, and Dr. Andersson.(47) Dr. Duret was the first one in the field of dentistry, he begun in 1971 by fabricating crowns with functional shape started with an optical impression of the abutment tooth in the mouth followed by designing and milling using a numerically controlled milling machine. Later he developed the Sopha® System, which had an impact on the later development of dental CAD/CAM systems in the world.(47,48) The second was Dr. Mörmann, the developer of the CEREC® system. He used new technology in a dental office at…show more content…
The Cerec CAD/CAM method was first developed at the University of Zurich by Mörmann and Brandestini in 1980.(51) In 1985; Cerec 1 was functioned for the first time to produce the first chairside inlay using Vita Mark I feldspathic ceramic material (Vita Zahnfabrik), and by 1988, Cerec 1 was capable of producing not only inlays but also onlays and veneers.(51) Cerec 1 system is a compact mobile unit with three basic components: a small video camera, a computer with screen, and a milling machine. To make a restoration with the Cerec CAD/CAM chair-side system (Sirona), the following sequence is carried out. First, the preparation is sprayed with titanium oxide powder to provide contrast for the optical scanner. The prepared tooth is scanned with an optical probe and the image is stored in a computer memory as a positive digital data model. The restoration is designed on a monitor screen, a block of a machinable ceramic is selected and the restoration is milled at the…show more content…
Bluecam uses blue-light, light emitting diodes (LEDs), to create highly detailed digital impressions using shorter wavelengths of light than earlier systems, which lead to increased precision. Unlike previous generations of scanners, which took one image at a time, the Bluecam is a “continuously on” camera that once you turn it on with a click of the mouse; it stays on, snapping images automatically as soon as the camera is held still over a patients’ tooth. This allows the clinicians to take a quadrant of images in a few seconds. All the user has to do is simply place the camera over the tooth, move the camera to the desired area to be captured and hold the camera still. Once the image is captured, the camera is moved to the next tooth and the subsequent images are captured to create a virtual model of the

    study was to evaluate the effect of finish line design and cement space thickness on the marginal accuracy and fracture resistance of monolithic zirconia crowns. Thirty crowns were fabricated from translucent zirconia (inCoris TZI) using Cerec in-Lab system, and divided into three main groups (10 each) according to the finish line type of the die (knife-edge, chamfer, and shoulder). Every group was divided into two subgroups (5 each) according to cement
