This system was designed to acquire data using photographs and a high-resolution scanner, and to mill restorations using a 5-axis machine.ĭr Andersson developed the Procera (now known as NobelProcera, Nobel Biocare, Zurich, Switzerland) method of manufacturing high-precision dental crowns in 1983. They called the device CEREC, an acronym for computer-assisted ceramic reconstruction.ĭr Rekow worked on a dental CAD/CAM system in the mid-1980s with colleagues at the University of Minnesota. By 1985, the team had performed the first chairside inlay using a combination of their optical scanner and milling device. He consulted with Dr Marco Brandestini, an electrical engineer, who came up with the idea of using optics to scan the teeth. Dr Duret later developed the Sopha system.ĭr Mörmann was the developer of the first commercial CAD/CAM system. He produced the first dental CAD/CAM restoration in 1983 and demonstrated his system at the French Dental Association’s international congress in November 1985 by creating a posterior crown restoration for his wife in less than an hour. Some of the most important figures in dental CAD/CAM development are Drs François Duret of France, Werner Mörmann of Switzerland, Dianne Rekow of the United States, and Matts Andersson of Sweden.ĭr Duret was the first person to develop a dental CAD/CAM device, making crowns based on an optical impression of the abutment tooth and using a numerically controlled milling machine as early as 1971. History of dental CAD/CAMĬomputer-aided design and manufacturing were developed in the 1960s for use in the aircraft and automotive industries, and were first applied to dentistry a decade later.

It also provides information on the advantages and disadvantages, describes the main products available, discusses how to incorporate the new technology into your practice, and addresses future applications. This article discusses the history of CAD/CAM in dentistry and gives an overview of how it works. Alternatively, the laboratory can do all of the design work directly on the computer based on the images received. When laboratories receive a digital impression, they can create a stone model from the data and either continue with traditional fabrication or rescan the model for milling. For example, dentists can take a digital impression and send it to a laboratory for fabrication of the restorations or they can do their own computer-aided design and milling in-house. In some cases, CAD/CAM technology provides patients with same-day restorations.ĭentists and laboratories have a wide variety of ways in which they can work with the new technology. The third challenge was to make tooth restoration easier, faster, and more accurate. The second challenge was to create restorations with a natural appearance. The first challenge was to ensure adequate strength of the restoration, especially for posterior teeth. CAD/CAM is also being used in orthodontics.ĬAD/CAM technology was developed to solve 3 challenges. The technology, which is used in both the dental laboratory and the dental office, can be applied to inlays, onlays, veneers, crowns, fixed partial dentures, implant abutments, and even full-mouth reconstruction. It also provides information on the advantages and disadvantages, describes the main products available, discusses how to incorporate the new technology into your practice, and addresses future applications.Ĭomputer-aided design (CAD) and computer-aided manufacturing (CAM) have become an increasingly popular part of dentistry over the past 25 years.
