1. Mechanical and Microstructural Properties of Monolithic Zirconia
Abstract : Zirconia has been widely used in dentistry to improve the strength of ceramic restorations maintaining aesthetics. In addition, zirconia is increasingly being used for monolithic crowns without veneering porcelain. READ MORE

2. Zirconia as a biomaterial for odontological applications : effects of composition and manufacturing processes on fracture resistance
Abstract : Background: Ceramics have long been amongst the most biocompatible materials known but their mechanical properties have limited their use. During the past few decades zirconia has aroused particular interest as a biomaterial because of its greater flexural strength, fracture resistance and toughness compared to other bioceramics.

3. On translucent yttria stabilized zirconia ceramics: Mechanical considerations, phase transformation and cement choices
Abstract : New zirconia formulations (4Y and 5Y-zirconias) have been introduced for prosthodontic therapy and are commercialized as “translucent” zirconias. No clinical information providing their survival rates or complications has been provided to the date. READ MORE

4. On core and bi-layered all-ceramic fixed dental prostheses, design and mechanical properties : studies on stabilized zirconiumdioxide
Abstract : Loss of teeth can affect a person’s self-esteem, social life, appearance and oral function. Reconstruction of a missing tooth has scientifically been shown to increase self-esteem and quality of life and to maintain oral function. For many patients a fixed dental prostheses (FDP) is preferred, either tooth- or implant-supported. READ MORE

5. Monolithic and semi-monolithic translucent zirconium-dioxide restorations : aspects on design, material and strength
Abstract : Although many clinical reports have shown high rates of clinical success associated with fixed dental restorations made of traditional zirconium-dioxide (zirconia), clinical failure due to improper design aiming to achieve high strength and optimal aesthetics, still occurs. Previous clinical and laboratory studies indicated that veneering porcelain and the connector represent the weak parts of the fully-veneered zirconia restorations where failure may occur. READ MORE
