Profile: Happersberger otopront GmbH produces direct restorations with the cerec technique. Powdering is a very important step with the cerec procedure. Only the powdered tooth-surface is readable by the 3D camera. The powder serves as an anti reflection surface. Different opacities of enamel dentin and root cementum would cause reflections, which are not correctly interpreted by the camera. The tooth surface should possibly have an even and thin powder coating. Our powder champ was developed after extensive tests with cerec-users in dental practice and in university clinics. Our device consists of a high quality hand piece and an air pressure unit.
