Silicone impression-taking of teeth is an established but inefficient technique for computer-aided manufacturing of dental prosthetics. Hence, intra-oral scanners based on optical technologies have been developed to optimize the process of impressioning and to enable a complete chairside workflow. However, during the scan, the presence of blood or saliva can cause critical model defects and the need...
