Effects of Substructure Color and Restoration Thickness on the Final Color of Ultra‐Translucent Zirconia Ceramics

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substructure color and restoration thickness on the final color of shade‐gradient ultra‐translucent zirconia ceramics. Material and Methods A total of 180 flat‐shaped ultra‐translucent zirconia specimens (5Y‐PSZ) with thicknesses of 0.4, 0.6, and 0.8 mm (n = 60) were fabricated and

Systematic Review Evaluating the Influence of Veneering Design on the Clinical Outcome of All‐Ceramic Implant‐Supported 3–4 Units and Full Arch Fixed Dental Prostheses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To systematically assess survival, failure, and complication rates of all‐ceramic implant‐supported monolithic and micro‐veneered FDPs (i‐FDPs) in partially/completely edentulous patients compared to veneered restorations. Materials and Methods An electronic search identified prospective clinical studies on all‐ceramic i‐FDPs with at

Assessing Color Inconstancy of CAD/CAM Materials: Influence of CIE White LED Illuminants and Substrate Shade

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To assess how the CIE white LED illuminants and substrate shade impact the color inconstancy of high‐translucency CAD/CAM materials. Materials and Methods From the spectral reflectance factors of Lava Ultimate‐LU, Grandio blocks‐GB, VITA Enamic‐VE, and VITA Mark II‐M specimens (n = 3/material) measured on nine background shades (ND1 ...

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Effects of Surface Abrasion With Airborne‐Particles and Surface Etching With Hydrofluoric Acid on Color Difference and Translucency of Nano‐Hybrid Ceramic

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effects of alumina airborne‐particle abrasion, glass‐bead airborne‐particle abrasion, and hydrofluoric acid etching of intaglio surfaces on the color difference and translucency of a nano‐hybrid ceramic after cementation to resin abutment specimens, and to analyze the relationships between surface roughness and these

Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.

Long‐Term Survival Rates of Dental Implants in Patients With Disabilities: A Retrospective Clinical Study With up to 10 Years Follow‐Up

Journal of Oral Rehabilitation, EarlyView.
Dental implants in patients with disabilities show high 10‐year survival (98.3%) when supported by principled screening and structured maintenance. This study reveals that while biological failure is rare post‐loading, frequent mechanical complications—predominantly decementation—remain a significant clinical challenge requiring vigilant long‐term ...
