  1. 1. Nanoscale Osseointegration Characterization of Biomaterials and their Interfaces with Electron Tomography

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Kathryn Grandfield; Uppsala universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electron tomography; transmission electron microscopy; hydroxyapatite; titanium; titania; bone; implant; osseointegration; interface; mesoporous; Materialvetenskap; Materials Science;

    Sammanfattning : Bone response is one of the key determining factors in the overall success of biomaterials intended for bone regeneration and osseointegration. Understanding the formation of bone at an implant surface may lead to the improved design of biomaterials for the future. LÄS MER

    Sammanfattning : Implant rehabilitation of edentulous patients is a predictable treatment with high long-term survival rates (90-95%) reported for the major dental implant systems after 5-10 years in function. Throughout recent years, different materials, implant surface technology, macrodesign, and surgical techniques have been developed to prevent aseptic loosening and lessen treatment time frames in order to apply immediate or early functional loading, especially in patients with reduced bone density.

  3. 3. Mechanisms of Osseointegration: Experimental Studies on Early Cellular and Molecular Events in vivo

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Omar Omar; Göteborgs universitet.; Gothenburg University.; [2010]

    Sammanfattning : The early cellular and molecular activities determining the early tissue response and bone formation at bone/implant interface are not fully understood. The general aim of the current thesis was to develop a model for studying the early molecular and cellular activities in different bone types, and in response to different implant surface properties.

  4. 4. The synergistic role of hierarchical macro- and mesoporous implant surface and microscopic view of enhanced osseointegration

    Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Författare :Guang Han; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porosity; cell adhesion; cell proliferation; surface topography; implant; bone-implant interface; argon ion beam polishing; osteogenesis; osseointegration; materialkemi; Materials Chemistry;

    Sammanfattning : The trend for designing of a titanium implant explored using different chemical compositions and crystallinity materials until people realized that the implant surface character was another important factor affecting the rate and extent of osseointegartion. Titanium received a macroporous titania surface layer by anodization, which contains open pores with average pore diameter around 5μm. LÄS MER

  5. 5. Towards better understanding of small joint arthroplasty in the hand. Silicone implants, osseointegrated implants and functional outcome

    Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Författare :Karin Möller; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; artroplasy; MCP; PIP; osseointegration; hand surgery;

    Sammanfattning : Today the most widely used implants for small joint arthroplasty in the hand are flexible silicone implants, introduced by Swanson in the 1960 s. They are encapsulated by connective tissue, which allows pistoning movements in the bone marrow canal This type of implant, mostly used in rheumatic patients, gives high patient satisfaction, relief of pain, correction of deformity and a changed arc of motion towards a more functional position.
