  1. 1. CAD Integrated Quality Control

    Författare :Martin Helgoson; John Corbett; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The thesis concludes the research work aimed at quality monitoring of parts associated with double twisted surfaces. Different CAD/CAM-based approaches and parameters for quality evaluation have been proposed. LÄS MER

  3. 2. On core and bi-layered all-ceramic fixed dental prostheses, design and mechanical properties : studies on stabilized zirconiumdioxide

    Författare :Deyar Mahmood Jallal Hadi; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Y-TZP; Zirconia; All-ceramic FDPs; connector design; radius; state-of-the-art; CAD CAM; multi-layer technique; veneering ceramic; split-file; over-pressing; dental porcelain; MECHANICAL PROPERTIES;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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.

  5. 4. Accuracy of virtually planned and CAD/CAM-guided dental implant surgery

    Författare :Andreas Pettersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :dental implant;

    Sammanfattning : The treatment with dental implants was introduced in the 1960s as an aid for patients who were missing teeth. Recently CAD/CAM guided surgical concepts have been launched on the market as a solution for treating single, partial or completely edentulous patients with dental implants. LÄS MER

  7. 5. On Clinical and Mechanical Aspects in Implant Supported Screw Retained Multi-unit CAD-CAM Metal Framework

    Författare :Marco Toia; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Conventionally casted frameworks have been considered the preferredsolutions for complete and partial restorations since the beginningof implantology. However, following technological development, thecomputer aided design/computer aided manufacturing (CAD-CAM)with milling the frameworks has been introduced as an alternativeoption with the potential of minimising inaccuracies, reducing theoperator dependence and offering a homogeneous structure with highmechanical properties.
