  1. 1. Mechanical and Microstructural Properties of Monolithic Zirconia

    Author : Keisuke Nakamura; Göteborgs universitet.; Gothenburg University.; [2015]
    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

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

    University dissertation from Umeå : Umeå universitet

    Author : Anders Sundh; Umeå universitet.; [2010]
    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.

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

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : David Huy Trinh; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alumina; Zirconia; NaKeywords: Alumina; Zirconia; Nanocomposite; Sputtering; Thin-Film; PVD; TEM; EELS; TECHNOLOGY Materials science; TEKNIKVETENSKAP 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

  5. 5. On Bone Regeneration in Porous Bioceramics - Studies in humans and rabbits using free form fabricated scaffolds

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Johan Malmström; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone regeneration; hydroxyapatite; zirconia; macroporosity; microporosity; free form fabrication; focused ion beam; scanning electron microscopy; transmission electron microscopy; rabbit; human;

    Abstract : The objective of the present thesis was to evaluate the effect of material chemistry and macroand micro-porosity on bone regeneration in association with synthetic, porous ceramic materials. Ceramic scaffolds were designed and manufactured for experimental and human studies using free form fabrication (FFF), a technique which produces the object layer by layer using data from CAD files.
