VOLUME 204 NO. 9 MAY 10 2008 | F. Beuer, J. Schweiger and D. Edelhoff
The article provides an overview of recent developments in CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) technologies for dental restorations. It highlights the increasing automation in dental technology, driven by the need to reduce costs and improve efficiency, particularly in high-wage regions like Western Europe and the USA. The benefits of CAD/CAM include access to defect-free, industrially prefabricated materials, enhanced quality and reproducibility, improved precision, and planning, as well as increased efficiency.
The article defines CAD/CAM systems, which consist of three components: a digitalization tool/scanner, software for data processing, and a production technology for transforming data into the desired product. It discusses three main production concepts: chairside production, laboratory production, and centralized fabrication in production centers. Each concept is described in detail, including the advantages and disadvantages of each.
The article also covers various components of CAD/CAM systems, such as scanners (optical and mechanical), design software, and processing devices (3-axis, 4-axis, and 5-axis milling devices). It explains different milling variants, including dry and wet processing, and the materials that can be processed, such as metals, resins, silica-based ceramics, infiltration ceramics, and high-performance oxide ceramics.
Finally, the article discusses the significance of CAD/CAM technology for dentists, emphasizing its impact on the quality and efficiency of dental prostheses production. It highlights the need for dentists to adapt their working procedures to CAD/CAM and milling technology, and it concludes by evaluating the advantages and disadvantages of computer-assisted production.The article provides an overview of recent developments in CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) technologies for dental restorations.
