Introduction. After tooth loss, the prosthetic space rarely remains unchanged. Generally, teeth migrate into the prosthetic space. The main treatment methods used by dentists to restore the morphology and function of the masticatory system are restorations such as crowns and bridges. Patients demands for more aesthetic restoration materials have led to an increased demand for metal-free restorations. This is made possible by the availability of new manufacturing systems combined with computer-aided manufacturing (CAD/CAM). Materials and Methods. We selected cases of scanned impressions using the Meddit scanner of both maxilla and mandibulary edentulous patients that needed dental bridges both in the anterior and posterior area. After the selection of the most suggestive cases we analized the modifications of the prosthetic potential space and the treatment options using the ExoCAD software for the digital bridge design. Results. An analyze of 25 selected cases with modifications of the prosthetic potential space is presented followed by the presentation of 4 representative cases in which we detailed the design procedure for the dental bridges. Conclusions. CAD/CAM technology is increasingly being used in dental practices. Advances in CAD/CAM technology allow the dentist to fabricate a temporary restoration for the patient in the dental office. Particularly in the case of bridges with modified prosthetic potential space, the dentist must review this technological step in order to achieve optimal prosthetic results.
