OBJECTIVES: To evaluate the fit of zirconia veneers made by either 3D printing or milling. METHODS: A typodont maxillary central incisor was prepared for a 0.5-mm-thick veneer and was reproduced 36 times from resin. Restorations were designed with a 20-µm-wide marginal and a 60-µm-wide internal cement gap, and were made from 3D-printed zirconia (LithaCon 3Y210, Lithoz, n=24) and milled zirconia (cercon ht, DentsplySirona, n=12). For milled zirconia, a drill compensation was needed to give the milling bur access to the intaglio surface...
