Case Description: A female patient, 63 years old, came on the Oral Rehabilitation consultation with non funcional complete removable upper and lower dentures. In the intraoral examination we observed a upper and lower alveolar ridge round shaped, irregular and with slight resorption. In the attempt to improve the retention and stability of the prosthesic elements, the creation of new prostheses using CAD/CAM technology, using the Dentca™system, was proposed. Discussion: The creation of complete dentures using CAD/CAM methods is currently a reality in the field of oral rehabilitation. The integration of this technology in the design and manufacturing of these prothesis allows to improve the quality of the prosthetic elements and facilitates the communication with the prothesis technician. The CAD/CAM method allows for a reduction in the number of appointments required until the prosthesis is delivered (a major advantage when rehabilitating elderly patients or whom take too long to get to the dental office); reducing the duration of treatment, reducing the overload and fatigue of the dental practitioner; reducing costs without compromising the quality of health care services; absence of polymerization contraction, resulting in increased accomodation of the prosthetic base to the alveolar ridge; Conclusion: The integration of CAD/CAM technology for manufacturing and design of complete dentures, besides contributing significantly to simplifying and facilitating the clinician's and laboratory's work, aims to contribute to improve the quality of the prosthetic element, in which case there was an increase in retention and stability of the prosthesis. Regarding the aesthetic component, despite the very satisfactory result when in the mouth, the characterization of the prosthesis was inferior compared to those made using the conventional method.
