  1. 11. Novel Materials and Implant Designs for the Treatment of Degenerative Disc Disease

    Författare :Salim Ghandour; Cecilia Persson; Donal McNally; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Topology Optimization; Spine; Intervertebral Disc; Papain; Additive Manufacturing; Biomechanics; Bone Cement; PMMA; Calcium Phosphate; Cage; Fusion; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Sammanfattning : The overarching objective of this thesis was to develop intervertebral implants for degenerated discs through design, fabrication, and mechanical validation. The research had four primary aims, each addressing different facets of implant development. LÄS MER

  3. 12. Physical Properties of Acidic Calcium Phosphate Cements

    Författare :Johanna Unosson; Håkan Engqvist; Cecilia Persson; Uwe Gbureck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The gold standard for bone replacement today, autologous bone, suffers from several disadvantages, such as the increased risk of infection due to the need for two surgeries. Degradable synthetic materials with properties similar to bone, such as calcium phosphate cements, are a promising alternative. LÄS MER

  4. 13. Resorbable Bone Cement for Augmentation of Hip Fracture

    Författare :Per Mattsson; Sune Larsson; Nils Dalen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : Surgical treatment of hip fractures is frequently associated with secondary fracture displacement, in part due to weak osteoporotic bone. So far, improvements have focused on new metal implants although an alternative could be to augment the bone that surrounds the implant. LÄS MER

  5. 14. Influence of a dental ceramic and a calcium aluminate cement on dental biofilm formation and gingival inflammatory response

    Författare :Katarina Konradsson; Jan van Dijken; Rolf Claesson; Lars Gahnberg; Umeå universitet; []
    Nyckelord :cements; ceramics; cytotoxicity; dental biofilm; gingivitis; interleukin-1; oral hygiene; resin composite;

    Sammanfattning : Dental restorative materials interact with their surrounding oral environment. Interaction factors can be release of toxic components and/or effects on biofilm formation and gingiva. In the end of the nineties, a calcium aluminate cement (CAC) was manufactured as a “bioceramic” alternative to resin composite. LÄS MER

  7. 15. Bone-compliant cements for vertebral augmentation

    Författare :Céline Robo; Cecilia Persson; Elizabeth Tanner; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone cement; low modulus; vertebroplasty; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Acrylic bone cement based on poly(methyl methacrylate) (PMMA) is commonly used during vertebral augmentation procedures for the treatment of osteoporosis-induced vertebral compression fractures. However, the high stiffness of the cement compared to that of the surrounding trabecular bone is presumed to facilitate the formation of new fractures shortly after surgery. LÄS MER
