  1. 1. Fixation of the cemented acetabular component in hip arthroplasty

    Författare :Gunnar Flivik; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; reumatologi; Surgery; Skelett; muscle system; rheumatology locomotion; Skeleton; Cement pressurization; Cement penetration; Acetabulum; Cancellous bone; muskelsystem; Total hip arthroplasty; RSA;

    Sammanfattning : In total hip arthroplasty cemented fixation of the acetabular component is a generally successful concept, but the rate of aseptic loosening and consequent revision surgery is still too high. One of the crucial factors for longterm implant survival is the initial fixation and stability. LÄS MER

  3. 2. Morcelised Impacted Cortico-Cancellous Bone Allografts in Revision Surgery for Endoprosthetic Loosening with Osteolysis

    Författare :Gösta Ullmark; Johan Kärrholm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Total hip arthroplasty; total knee arthroplasty; graft impaction; revision; histology; biomechanic; cement; positron emission tomography; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Revision total hip arthroplasty (RTHA) and filling of the bone defects with impacted particulated bone allograft is the concept that has been studied in this thesis. In three in vitro models, biomechanical aspects of morcelised and impacted bone allografts were studied. LÄS MER

  4. 3. Structure of Hardened Cement-Fly Ash Systems and Their Related Properties

    Författare :Aimin Xu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water vapour sorption isotherms; thermogravity analysis; mortar; scanning electron microscopy; differential thermal analysis; X-ray diffraction analysis; fly ash; pore structure; microstructure; cement paste;

    Sammanfattning : The influence of fly ash on the pore structure and microstructure of cement paste and mortar has been investigated. The methods applied include water vapour sorption isotherms, scanning electron microscopy, X-ray diffraction analysis and thermogravity/differential thermal analysis. LÄS MER

  5. 4. On healing after periapical surgery and different retrograde root-filling materials. A clinical and histological study

    Författare :Dan-Åke Wälivaara; Göteborgs universitet; []
    Nyckelord :periapical surgery; ultrasonic preparation; IRM; thermoplasticized gutta-percha; Super-EBA; mineral trioxide aggregate; root-filling status; lesion size; lesion type;

    Sammanfattning : Aims: The outcome from conventional endodontic therapy does not always result in a healing of the periapical area, thus leaving a remaining lesion with or without symptoms. The primary treatment alternative is a revision of the orthograde root-filling if applicable. A second treatment alternative might be a periapical surgery procedure. LÄS MER

  7. 5. Calcium Aluminate based Cement as Dental Restorative Materials

    Författare :Lars Kraft; Charles Lloyd; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : This thesis presents the results from the development process of a ceramic dental filling material based on calcium aluminate cement. The main focus of the work concerns dimensional changes during setting, hardening and curing and the understanding of the factors controlling the dimensional stability of the system. LÄS MER
