  1. 16. 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

  3. 17. On the influence of biochemical coating on implant bone incorporation

    Författare :Kostas Bougas; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Implantat används idag med goda resultat för att ersätta förlorade tänder. Tandimplantat opereras in i käkbenet och agerar som en konstgjord rot för en konstgjord tand eller för att förankra en protes. Implantatens ytor har utvecklas med åren från att vara släta till måttligt råa. LÄS MER

  4. 18. On implant integration in irradiated bone : clinical and experimental studies

    Författare :Jan Nyberg; Börje Svensson; Christer Dahlin; Carina B. Johansson; Bo Sunzel; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implant; osseointegration; radiation therapy; bone remodeling; histomorphometry; hyperbaric oxygen therapy; gene expression and in vivo; Surgery; Kirurgi;

    Sammanfattning : Radiation has an impact on the processes involved in bone- healing, regeneration and remodeling. The mechanisms that cause impaired bone healing of dental implants are not fully understood. Adjunctive treatments to revers radiation effects are limited. LÄS MER

  5. 19. On the bone response to oxidized titanium implants. The role of microporous structure and chemical composition of the surface oxide in enhanced osseointegration

    Författare :Young-Taeg Sul; Göteborgs universitet; []
    Nyckelord :Oxidized titanium implants; micro arc oxidation; oxide growth; surface oxide properties; bone; biomechanical tests; histomorphometry; enzyme histochemistry.;

    Sammanfattning : Background: Titanium implants have been widely used clinically for various types of bone-anchored reconstructions. A thin native oxide film, naturally formed on titanium implants contacts with bone tissue and has been considered to be of great importance for successful osseointegration. LÄS MER

  7. 20. On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants

    Författare :Byung-Soo Kang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegrated titanium implants; Magnesium and Calcium Incorporated Bioactive Titanium Oxide; Metal Plasma Immersion Ion Implantation and Deposition; Micro Arc Oxidation; Clinical Implants; In Vivo Bone Response;

    Sammanfattning : Background: Surface properties of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical performance by changing surface properties. LÄS MER
