  1. 1. Tissue reactions to biomaterials

    Författare :Agneta Rosengren; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytochemistry; Histology; Macrophages; Cryosubstitution; Proteins; Immunohistochemistry; Titanium; Implants; PTFE; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Sammanfattning : The biological response to different implanted biomaterials vary. The relative importance of factors in the material and host for this variation are at present incompletely known. LÄS MER

  3. 2. Factors affecting peri-implant tissue reactions

    Författare :Margareta Hultin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dental implants long-term maintenance; microbiota; inflammation; periodontitis; periimplantitis smoking crevicular fluid.;

    Sammanfattning : Screw- shaped titanium implants are today routinely used m the substitution of lost teeth. In this thesis some of the biological factors related to the long-term survival and maintenance of dental implants were studied. The first arm of these studies was to evaluate the neutrophil activation around teeth and dental implants (Papers I & II). LÄS MER

  5. 4. Tissue engineering in blood vessels

    Författare :Gisela Helenius; Göteborgs universitet; []
    Nyckelord :tissue engineering; vascular graft; endothelial cells; smooth muscle cells; thrombogenicity; mechanical properties; scaffold; bacterial cellulose;

    Sammanfattning : Severely occluded coronary- and peripheral arteries, caused by atherosclerotic plaques, are treated with bypass surgery. Autologous veins are the most commonly used replacement graft. Among the patients that need a vascular bypass, 5-10% lack appropriate replacement veins due to previous surgery of bad quality of the vessels. LÄS MER

  7. 5. On tissue reactions to dentin as a bone substitute material

    Författare :Payam Farzad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grafted dentin; tissue reaction; bone blocks; dental implants; experimental study;

    Sammanfattning : Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ability equivalent to autogenous bone but without the limitations of allogenic, xenogenic and synthetic bone are constantly ongoing.
