Post‐curing effects on mechanical properties staining resistance of a 3D‐printed resin versus a direct composite for definitive restorations

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated the mechanical performance and staining resistance of a three‐dimensional (3D)‐printed resin (VarseoSmile Crown Plus) subjected to different post‐curing times (0, 5, 10, 15, and 20 min), compared with a conventional nanofilled resin composite (Filtek Z350XT).

Effect of in‐office bleaching on the color stability of bulk‐fill resin composites immersed in staining beverages

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated the impact of in‐office bleaching on color stability of bulk‐fill composites submitted to staining. Bulk‐fill (Aura, Opus, and Filtek One) and nanofilled (Filtek Z350) composite specimens were submitted to the following: control (CT); bleaching and immersion in distilled water (BL); and bleaching with daily 15‐min ...

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.
