Abstract
CAD-CAM techniques are based on innovative procedures that have appeared in the last decades. They tend to expand in many domains while diversifying the products offered to the recipients.
Digital technology is also used in dental medicine, replacing a big part of the conventional fabrication procedures with modern procedures. In oral rehabilitation (e.g.: using a complete denture) there is a rising interest regarding these procedures. Laser beams and CBCT (cone beam computer tomography) have been recently used to gather data in the orofacial sphere. Some of the available commercial systems use subtractive techniques (using milling machines with 3 or 5 axes) or additive techniques such as rapid prototyping or stereolithography in the fabrication process of the final product. Knowledge regarding the particularities of different commercial systems is essential. The benefits of using these techniques are multiple: speed, precision, data reproducibility, comfort, higher efficiency and reduced costs due to the standardization of the treatment steps.
Key words: CAD-CAM commercial systems, digital denture, CAD-CAM denture, rapid prototyping, stereolithography, CNC milling machines.
