Complete arch implant rehabilitation using subtractive rapid prototyping and porcelain fused to zirconia prosthesis: A clinical report

The applications of various technological advances in implant dentistry and in all aspects of the diagnostic, treatment planning, surgical, and restorative phases are gaining popularity. Additive rapid prototyping and computer-aided design/computer-aided manufacturing (CAD/CAM) technology are used to generate stereolithographic surgical guides and prefabricated interim prostheses to facilitate implant surgery and immediate loading, respectively. Subtractive rapid prototyping is used for fabrication of zirconia frameworks for definitive implant prostheses. This clinical report describes the comprehensive application of these technological advances in implant rehabilitation to optimize surgical and prosthodontic outcomes as well as patient comfort.
