Additive Manufacturing for a Metal Framework


Online now and in the August issue of the Journal of Prosthodontics, Drs. Keaton Forrester, Ryan Sheridan, and Rodney D. Phoenix present the results of a study regarding the accuracy of additive manufacturing (AM) in comparison to conventional casting, specifically for fabrication of complete palatal coverage metal frameworks.

The authors found that CAD/cast and selective laser melting techniques were as or more accurate than the conventional technique for producing an uncomplicated framework design. These results indicate that digital workflows using these specific AM techniques can be recommended for uncomplicated framework designs.

This research was awarded 2nd place at the John J. Sharry Research Competition at the 2018 ACP Annual Session, Baltimore, MD.
