  2. 21. On a novel technique for preparation and analysis of the implant surface and its interface to bone

    Author : Anders Palmquist; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Focused Ion Beam FIB ; Transmission electron microscopy TEM ; Scanning electron microscopy SEM ; osseointegration; rabbit; human; titanium; titanium alloy; surface analysis; bone-implant interface analysis; ultrastucture; surface modification; laser;

    Abstract : The ultrastructural and biomechanical properties of the bone-implant interface are important factors for implant performance. For further understanding of the osseointegration process novel tools enabling analysis of the intact interface in high resolution is needed, preferably combined with histology and biomechanical tests.

  4. 22. Radiographic follow-up analysis of Br?nemark? dental implants

    Author : Solweig Sundén Pikner; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cluster effect; Dental implants; Dependency; Diagnostic accuracy; Long-term follow-up; Marginal bone level; Observer variation; Osseointegration; Prediction;

    Abstract : Radiography plays an important role in clinical routine practice and in research projects evaluating dental implants, among them Br?nemark? System. Presence of a peri-implant radiolucency has been used in studies as a criterion for implant failure without knowledge of its diagnostic accuracy. READ MORE

  5. 23. In vivo and in vitro studies of polyetheretherketone: bone formation, inflammatory response and biofilm formation

    Author : Sargon Barkarmo; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PEEK; polyetheretherketone; hydroxyapatite; nanotopography; osseointegration; cytokines; biofilms; biomaterials; dental materials; titanium; nanocoated;

    Abstract : In prosthetic dentistry, restorative materials are used to replace missing teeth and tissues, so as to maintain oral functionalities and comfort for the patient. Depending on the clinical problem, metals, ceramics or polymers, are used both in dentistry and orthopedics. READ MORE

  6. 24. Biodegradable magnesium implants, immunomodulation, and tissue repair/regeneration

    Author : Heithem Ben Amara; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipose tissue; Biodegradable implants; Bone–implant interface; Bone marrow; Inflammation; Cellular mechanotransduction; Gene expression; Immunohistochemistry; Magnesium; Neovascularization; Osseointegration; Soft tissue injuries;

    Abstract : The century-old paradigm of holding fractures with a metallic implant to enable bone repair, known as osteosynthesis, is still used today without alteration. Patients are increasingly being treated with metallic implants made of magnesium (Mg) that secure osteosynthesis and are reabsorbed in situ without the surgical re-entry that requires their permanent analogs.

  7. 25. The osteogenic potential of human mesenchymal stem cells: Novel markers and key factors for differentiation

    Author : Cecilia Granéli; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenchymal stem cells; Mesenchymal stromal cells; Osteogenic differentiation; Adipogenic differentiation; Bone regeneration; Inflammation; Monocytes; Infection; Bacterial membrane vesicles; Compromised bone healing; Cell surface proteins; CD-markers; Osseointegration; Regenerative medicine;

    Abstract : Mesenchymal stem cells are multipotent stem cells with ability to differentiate into cells of the connective tissue lineage, such as adipocytes, osteoblasts and chondrocytes, both in vitro and in vivo. The main objective of the present thesis was to study different aspects of the osteogenic potential of MSCs. READ MORE
