  1. 1. 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 :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

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

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

  3. 3. Evaluation of computer-assisted virtual treatment planning and template-guided surgery in dental implant treatment

    Författare :Ai Komiyama; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Dental implant; computer-guided surgery; surgical template; flapless surgery; immediate loading; CAD CAM technique; marginal bone loss; soft tissue condition; accuracy;

    Sammanfattning : One of the newly introduced concepts in implant dentistry is computer-guided surgery. The development of 3D implant planning software and imaging technology provide clinicians with 3D information of patients bony structures. LÄS MER

  4. 4. Prosthetic fitting : stump-socket interaction in transtibial amputees

    Författare :Magnus Lilja; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis is comprised of five different studies, all concerning the interaction between the transtibial amputation stump and the prosthetic socket. The aim was to analyse some of the factors influencing this interaction.CAD CAM (Computer Aided Design Computer Aided Manufacturing) and roentgen were used as measuring instruments. LÄS MER

    Sammanfattning : The objective of this thesis was to find ways of improving part-load efficiency for a spark ignition engine by studying the effects of variable-valve actuation on fluid flow and combustion. The in-cylinder flow was measured with laser doppler velocimetry, LDV, and particle image velocimetry, PIV. LÄS MER
