ADDITIVE MANUFACTURING AND 3D PRINTING IN DENTISTRY

CAD / CAM techniques applied to solving dental problems demonstrate that there are many solutions available on the market to help the dentist individually perform the rehabilitation of a dental element to meet the specific needs of each patient. These manufacturing technologies close a digital workflow, potentially managed entirely by the dentist, which involves taking the impression of the oral cavity and the dental elements present through an intraoral scanner with the generation of a file on which to create the CAD project and to start extrapolating the file of the final work to be produced by subtractive or additive CAM. The 3D printing techniques allow to work easily with polymeric and ceramic materials, in order to create dental crowns that can satisfy practically all the needs encountered in the dental field. Leaving aside the techniques applied to polymers, this PhD project focuses on the applications of ceramic materials. This PhD thesis focuses on the design, study and implementation of 3D printing of ceramic supports specifically dedicated to the stabilization of dental implants. Through the development of a prototype of a 3D printer, it was possible to obtain the printing of ceramic products useful for the intended purpose.
