Translucency of 3D‐Printed 3Y‐ and 5Y‐Doped Zirconia

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate and compare the translucency of 3D‐printed zirconia materials: 3Y tetragonal zirconia polycrystal (3Y‐TZP) and 5Y partially stabilized zirconia (5Y‐PSZ). Material and Methods 3D‐printed 5Y‐PSZ and 3Y‐TZP materials fabricated using digital light processing (DLP) were investigated.

Impact of Zirconia Three‐Unit Resin‐Bonded Fixed Partial Dentures in the Posterior Region on Oral Health‐Related Quality of Life: A 12‐Month Longitudinal Observation

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Introduction Patient‐reported outcome measures (PROMs) remain limited in prosthodontics, including for ceramic resin‐bonded fixed partial dentures (RBFPDs), despite their growing relevance in minimally invasive practice. Oral health–related quality of life (OHRQoL) can be reliably assessed using the validated Oral Health Impact Profile −14 ...
