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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

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

    Abstract : 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. READ MORE

  2. 2. Aspects of oral implant technology and osseointegration

    University dissertation from Malmö University, Faculty of Odontology

    Author : Rainde Naiara Rezende de Jesus; Malmö University.; [2019]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

    Abstract : 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 technologies, macrodesigns, and surgical techniques have been developed to enhance osseointegration and lessen treatment timeframes, for example allowing immediate or early functional loading in patients with reduced bone density.

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

    University dissertation from Göteborg : University of Gothenburg

    Author : Omar Omar; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; bone; gene expression; bone-implant interface; qPCR; inflammation; cytokine; chemotaxis; chemokine; integrin; bone formation; remodeling; in vivo; rat; immunohistochemistry; ultrastructure; biomechanical torque test;

    Abstract : 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

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

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

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

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

    Abstract : 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.
