Titolo della tesi: Digital Full-arch - A randomized controlled trial
Implant-supported prosthetic rehabilitations represent an important evolution in modern dental practice. This approach, which involves the insertion of dental implants to replace missing natural roots, allows for the stable support of fixed or removable prostheses. Dental implants, typically made of titanium, osseointegrate with the bone, offering a long-lasting and functionally efficient solution for patients with partial or total edentulism. Compared to traditional solutions, such as removable dentures, implant-supported rehabilitations significantly improve the quality of life, ensuring better chewing function, aesthetics and psychological perception of the patient.
Implantology, today, represents a consolidated standard in the treatment of tooth loss, thanks to decades of research and technological advances. In the specific field of prosthetic rehabilitations supported by osseointegrated implants, the prosthetic and biological results are obtained with a completely digital workflow, using different CAD/CAM materials.
Digital flow is a modern technique that consists of taking impressions with intraoral scanners, digitally designing the prosthesis using dedicated CAD software, and constructing the prosthesis using computerized CAM milling procedures from a block of porcelain or prosthetic alloy (to be subsequently stratified with feldspar ceramic).
The aim of this study is to analyze (via FEA) the mechanical response of cobalt-chromium and monolithic zirconia structures, used for the rehabilitation of complete arches with fixed prostheses on implants. The results obtained have demonstrated that these two materials are able to mechanically resist the action of the applied force .
