title: [Stereolithography as an additive technique in dentistry].
abstract: 3D-CAD constructions offer the application of CAM-techniques for the fabrication of dental restorations. CNC-units are generally used for milling and grinding. However, the application of new additive working technology enables the construction of  3D-solid models. In the field of rapid prototyping   (RP), the process of "three-dimensional printing" allows the fabrication of patterns for the lost-wax casting technique from materials such as wax or resin. This paper describes the use of a light-curing fluid resin in combination with a UV-light projection in means of stereolithography (SL). The presented CAM unit (Perfactory, DeltaMed, D-Friedberg) reduces processing times of large casting patterns by using CAD constructions. This concept focuses on the advancement of the common casting technique in dental technology by application of CAD/CAM technology.
