  1. 1. On the Immune Regulation of Bone Response to Biomaterials

    Författare :Ricardo Trindade; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterial; Immune System; Osseointegration; Foreign body reaction; Immune modulation; Titanium; Copper; Polyether ether ketone; PEEK;

    Sammanfattning : Osseointegration is the biological basis for bone anchorage of oral implants, and revolu-tionized the replacement of lost teeth. It is also applied in bone anchored hearing aids and limb replacement in amputees. LÄS MER

  3. 2. On the Development of Mucin-based Biomaterial Coatings

    Författare :Tomas Sandberg; Karin Caldwell; Jan Carlsson; Thomas Arnebrant; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucin; Biomaterial; Surface-exposed protein; XPS; Neutrophil; Cell morphology; SEM; QCM-D; Viscoelasticity; Protein-stabilization; HNL; Coating; MG1; BSM; PGM; SEC-MALS-RI; Mucin quantification; Protein adsorption; Ellipsometry; Biomaterials; Biomaterial;

    Sammanfattning : Owing to their key role in mucosal functioning as surface barriers with biospecific interaction potentials, the mucins are interesting candidates for use as surface modifiers in biomaterials applications. In this work, “mild” fractionation procedures were used to prepare mucins of bovine (BSM), porcine (PGM), and human (MG1) origin. LÄS MER

  4. 3. On magnesium-modified titanium coatings and magnesium alloys for oral orthopaedic applications : in vitro investigation

    Författare :Francesca Cecchinato; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biocompatible material; Bone substitutes; Biomaterial; Dentala implantat;

    Sammanfattning : In dentistry and orthopaedic surgery, research to find and developimproved biomaterials is progressing rapidly.Of specific interest is to accelerate bone formation around theimplant surface, which could improve the reliability of the implanteven in patients with compromised situations.

  5. 4. Micromechanics of softwoods in the transverse plane : effects on cell and annual ring scales

    Författare :Carl S. Modén; Lars Berglund; Per Johan Gustafsson; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära; Engineering mechanics; Teknisk mekanik; Biomaterials; Biomaterial;

    Sammanfattning : Transverse mechanical properties of wood are important in many practial applications and an interesting scientific subject. A very low transverse shear modulus has been identified in spruce, which causes large strain concentrations in wood structures. LÄS MER

  7. 5. Ridge alterations following tooth extraction and implant placement

    Författare :Giuseppe Cardaropoli; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The purpose of the present series of investigations was to study the healing following tooth extraction and implant placement. In an animal model, the healing sequence of tooth extraction sites (Study I), the influence of the periodontal ligament (PDL) on the healing of extraction sockets and the effect of various biomaterial on the healing of bone defects (Study II), and the healing of different bone block grafts placed on the surface of a narrow ridge (Study III) were investigated.
