Damage tolerance of six dental zirconias with different translucencies

Biomaterial Investigations in Dentistry, 2020
Purpose High-translucent dental zirconia has been introduced as a suitable material for anterior monolithic restorations. The material composition differs from traditional 3Y-TZP both with regard to yttria content and grain size.

X-ray photoemission spectroscopy determination of the InN/yttria stabilized cubic-zirconia valence band offset [PDF]

, 2007
The valence band offset of wurtzite InN(0001)/yttria stabilized cubic-zirconia (YSZ)(111) heterojunctions is determined by x-ray photoemission spectroscopy to be 1.19±0.17 eV giving a conduction band offset of 3.06±0.20 eV.

High Temperature Stability of Yttria Stabilized Zirconia

Netsu Bussei, 2007
イットリア安定化ジルコニアは熱物性に関する標準物質候補材料として研究が進められている。本研究では、ファインセラミックス共通試料であるリファセラムZR1（ジルコニア）を用い、標準物質材料として使用する際に重要となる高温安定性の評価を行った。高温安定性は、200～ 1500℃の温度で熱処理を行ったときの、熱処理前後の熱拡散率の変化より評価した。900℃以下の熱処理では熱拡散率に変化がほとんど見られなかったが、1000℃以上で熱処理すると、結晶相の変化や相分離および粒界に発生した亀裂などによって熱拡散率に変化が生じることが明らかになった。これらの結果より、リファセラムZR1 は900℃以下であれば安定であり、標準物質として適用できると判断された。

Optimizing Hard and Soft‐Tissue Esthetics With Anterior Cantilever Zirconia Ceramic Resin‐Bonded Fixed Dental Prostheses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The replacement of missing maxillary lateral incisors poses both functional and esthetic challenges, not only from a restorative but also from a periodontal aspect. This case report presents a step‐by‐step protocol for ideal hard and soft‐tissue esthetics with cantilever zirconia ceramic resin‐bonded fixed dental prostheses (RBFDPs).

Fatigue Performance and Failure Loads of Composition‐Gradient Multilayer Zirconia: Partial‐Coverage Restorations Versus Single Crowns at Different Thicknesses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study investigated the influence of restoration type (partial‐coverage versus crown) and ceramic‐layer thickness on the fatigue behavior and failure load of monolithic composition‐gradient multilayer zirconia (4Y‐PSZ/5Y‐PSZ) molar restorations. Material and Methods Seventy‐two CAD/CAM‐fabricated monolithic zirconia restorations (
