coping tradizionale scan body 39.L’accuratezza del processo di digitalizzazione dipende da: !- tecnica di scansione del clinico (a zig-zag o lineare) - sistema di scanner utilizzato (microscopia cofocale, paralella, a raggio laser, a luce strutturata) - forma e dimensioni dello scan body 44 40.Questi modelli non sono concepiti per realizzare delle protesi dall’inizio Possono solo essere utilizzati per posizionare le strutture realizzate tramite le tecnologie cad-cam per poter applicare la ceramica e controllare i punti di contatto.46 METODI DI FABBRICAZIONE !Fresatura da un blocco Sinterizzazione al laser di polvere Polimetilmetacrilato (PMMA) Resina composita Leghe metalliche (vili, titanio) Vetro ceramiche (Disilicato di litio, leucite) Zirconia 42.Control of the costs 2.Enahncement of the application spectrum (edentulous jaw) 3.Introduction of trans-gengival scanners 4.Optical coherence tomography (OCT) !!!
