Digital Dentistry Technology
New College of Dentistry faculty member Leonardo Nassani, DMD, from the Division of Restorative and Prosthetic Dentistry, has implemented the instruction of computer aided manufacturing (CAM) technology into the DDS curriculum, which is a first for the college. Working in partnership with Ohio State’s Prior Health Sciences Library and the College of Engineering, Dr. Nassani, has second-year dental students using 3D printers to print provisional fixed dental prostheses. The photos below outline the process.
Mathea McGuire designs the onlay restoration for the tooth she has prepared and scanned. The restoration will then be attached to a keychain tag with her name before being 3D printed.
Having designed their onlays, students must prepare their files on the slicer software and add printing support beams before sending them to the 3D printer.

Eva Mandybur pours the photopolymer resin into the 3D printer tank and then prints the provisional onlay and keychain tag. (Peggy, can you photoshop the red phone the student has in the background and make it gray like their scrubs? That way it won’t be noticeable)
Quinn Saluan removes the printed keychain tag and onlay provisional from the printing platform.
Ajeet Gill and Dr. Nassani place the printed keychain tag and onlay provisional into the washing tray to wash and cure the printed objects.
Provisional onlays and keychain tag are cured under a UV-LED light after the wash to provide final solidification of the material.
