  2. 1. Mechanical and Microstructural Properties of Monolithic Zirconia

    Author : Keisuke Nakamura; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zirconia; flexural strength; microstructure; fracture resistance; monolithic crown; low-temperature degradation; phase transformation;

    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

  4. 2. Zirconia as a biomaterial for odontological applications : effects of composition and manufacturing processes on fracture resistance

    Author : Anders Sundh; Göran Sjögren; Krister Nilner; Umeå universitet; []
    Keywords : CAD CAM; ceramics; HIPing; Mg-PSZ; veneering; Y-TZP; zirconia;

    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.

  6. 4. Synthesis and Characterisation of Magnetron Sputtered Alumina-Zirconia Thin Films

    Author : David Huy Trinh; Hans Högberg; Anders Hårsta; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Alumina; Zirconia; NaKeywords: Alumina; Zirconia; Nanocomposite; Sputtering; Thin-Film; PVD; TEM; EELS; Materials science; Teknisk materialvetenskap;

    Abstract : Alumina-Zirconia thin films were grown on a range of substrates using dual magnetron sputtering. Film growth was achieved at a relatively low temperature of 450 °C and at higher temperatures up to 810 °C. The films were grown on well-defined surfaces such as silicon (100) but also on industrially relevant substrates such as hardmetal (WC-Co). READ MORE

  7. 5. On translucent yttria stabilized zirconia ceramics: Mechanical considerations, phase transformation and cement choices

    Author : Sebastian Franco Tabares; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zirconia; translucent; yttria; air-borne particle abrasion; 10-MDP; cement;

    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
