Objectives Interim restorations are an essential part of the prosthodontic therapy, but they can give some problems, such as fractures. A fractured provisional can be repaired, but the initial mechanical strength is lost. Our aim is to introduce a sapioneering technique meant to obtain a copy of a functionalized interim prosthesis. Materials and methods An interim crown was relined and polished. Just before cementation, it was removed from the mouth and scanned with an intraoral scanner (3D Progress, MHT Srl, Verona, Italy). A 3D model of both the outer and inner surface was generated and sent to a milling centre. Results A new crown, as a copy of the interim prosthesis, was manufactured by using a material available on the market. The manufactured prosthesis was clinically acceptable and needed only minor occlusal adjustments. Conclusions Prostheses produced with this workflow are cheaper, less time-consuming and more durable as compared with a chairside conventional method. Interim or durable prostheses can be milled without the need for Computer Aided Design (CAD) and the relevant costs.
