| Abstract | ||
A fixed dental prosthesis is used for restoring oral function and aesthetics when replacing missing teeth. This allows the preservation and improvement of the patient's appearance, comfort, physical and mental health. Numerous variables can influence the precision and marginal adaptation of an FDP, including the precision of the impression, the fabrication of the master cast, and the method of fabrication of the prosthesis. These variable methods of fabrication can be broadly classified into conventional and digital methods. The conventional method had demonstrated remarkable success; however, this procedure is unfavorable for patients. An alternative was needed to minimize the laboratory variables and the human factor generated by the inconsistency of the dimensional changes of different materials used and also to reduce patient discomfort. Therefore, digital techniques, known as CAD/CAM systems, that were recently introduced have gained great popularity. Although even in a digital workflow, it is necessary to create a functional model in order to determine and correct the restoration's fit. The manufacturing step of digital technology can be categorized as subtractive (milling) and additive (3D printing). Additive manufacturing produces precise accurate prosthesis by minimal materials and less cost. Additionally, multiple restorations can be fabricated simultaneously. | ||
