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

open access: yesJournal 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.

Rehabilitation in Cases of Maxillary Lateral Incisor Agenesis Using Zirconia Implant and Abutment: Finite Element Analysis and Systematic Review

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The use of narrow‐diameter implants has emerged as a strategy to compensate for the reduced bone dimensions of maxillary lateral incisor agenesis (MLIA). This study integrates finite element analysis (FEA) and systematic review (SR) to assess the biomechanical and clinical viability of implant‐supported crowns in MLIA scenarios ...

Effect of Occlusal Adjustment and Subsequent Repolishing on the Translucency Parameter, Contact Angle, and Flexural Strength of Different Types of Glazed Monolithic Zirconia

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study evaluated the effects of material and surface condition (glazed vs. polished after simulated occlusal adjustment) on translucency parameter, contact angle, and flexural strength of four monolithic zirconia. Materials and Methods Disk‐shaped specimens (n = 80, Ø12 × 1 mm) were fabricated from four monolithic zirconia ...

Translucent zirconia polycrystals prepared from nanometric powders

open access: yesProcessing and Application of Ceramics, 2015
The aim of the present study was investigation of synthesis and sinterability of nanometric zirconia solid solution powders containing 8mol% and 3mol% of Y2O3. The powders were prepared by the hydrothermal treatment of the co-precipitated gels, which resulted in very fine powders with particle sizes <10 nm.
