CAD-CAM implant-supported fixed complete dental prosthesis with titanium milled molars: A clinical report

Abstract

Implant-supported fixed complete dental prostheses have been associated with a high implant success rate in long-term studies. However, they have also been associated with a high frequency of prosthetic complications. The most frequent and primary prosthetic complication has been the fracture or wear of the occlusal surface of acrylic resin teeth that are typically attached to a metal framework. The design of the framework in this clinical report involved the incorporation of metal occlusal surfaces for the posterior first molars to the framework. The titanium framework was fabricated with computer-aided design and computer-aided manufacturing (CAD-CAM) technology. The remaining teeth were restored in a conventional manner with acrylic resin denture teeth bonded to the titanium framework. This was expected to maintain the occlusal vertical dimension and also reduce the frequency of the primary complications associated with these prostheses.
