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

    Författare :Johan Malmström; Göteborgs universitet; []
    Nyckelord :bone regeneration; hydroxyapatite; zirconia; macroporosity; microporosity; free form fabrication; focused ion beam; scanning electron microscopy; transmission electron microscopy; rabbit; human;

    Sammanfattning : 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.

  3. 22. On the biological response to different biomaterials under normal and irradiated conditions

    Författare :Louise Rydén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; bone; fibrosis; hydroxyapatite; inflammation; irradiation; Osseointegration; silicone; soft tissue; titanium;

    Sammanfattning : There are several challenges when introducing an implant into a host. Concerning soft tissues, major complications are fibrosis and capsule contracture, whereas for bone, failure of osseointegration may occur. LÄS MER

  4. 23. On magnesium-containing implants for bone applications

    Författare :Silvia Galli; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The biomedical technologies for bone application are employed in millions of patients every year to restore function and aesthetics following trauma, diseases and congenital deformities. They achieved significant advancements in the last decades and have resulted in the development of implants that function for long periods of time. LÄS MER

  5. 24. Hyaluronan Derivatives and Injectable Gels for Tissue Engineering

    Författare :Kristoffer Bergman; Tim Bowden; Jöns Hilborn; Jeffrey Hubbell; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; Hydrogel; Tissue Engineering; Scaffold; Minimally invasive strategy; Bone morphogenetic protein; Hydroxyapatite; Bone; Cartilage; Tendon; Polymer chemistry; Polymerkemi;

    Sammanfattning : The present work describes the preparation of hyaluronan derivatives and hydrogels with potential use in tissue engineering applications. A potentially injectable hydrogel consisting of hyaluronan and collagen was successfully used to grow neurons in vitro by encapsulation of neural stem and progenitor cells. LÄS MER

  7. 25. Craniofacial bone tissue engineering with biomimetic constructs

    Författare :Gregory Tour; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bone regeneration;

    Sammanfattning : The repair of bone defects and nonunions remains a significant clinical problem in orthopedic and maxillofacial reconstructive surgery. Tissue engineering offers a potential approach to overcome existing limitations related to auto- and allograft tissues. LÄS MER
