Alongside the development of digital devices and materials, the concept of digital dentistry has been advancing throughout the field of prosthetic dentistry. Patients with missing teeth often visit dental clinics in a functionally and esthetically disrupted state. Provisional restorations play an important role in setting the patient-specific information, such as the position and alignment of teeth for esthetics, pronunciation, lip support, vertical dimension and occlusal plane. In conventional methods, there are many difficulties in reflecting provisional prosthesis to final restorations. However, with the double scanning method, which is a process of superimposing and replicating scanned models of provisional prosthesis on a definitive model, it is easier to reflect provisional restorations to final ones. It also has the advantages of simplifying the manufacturing process, and making it possible to reproduce the same prosthesis when it has been fractured or lost. In this case report, two patients went through a provisional restoration phase to evaluate function and esthetics. The final monolithic zirconia implant restorations were fabricated using the double scanning method. These cases are presented to show that with CAD/CAM technology and double scanning method, it is possible to fabricate an esthetic and functional final restoration that reflects the provisional restoration.
