  2. 11. On the role of surface properties for implant fixation : From finite element modeling to in vivo studies

    Author : Patrik Stenlund; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implant stability; Removal torque; Surface roughness; Surface chemistry; Finite element analysis; Experimental; In vivo; Osseointegration; Mechanical loading; Bone regeneration; Biomechanics;

    Abstract : The aim of this thesis was to gain a deeper understanding of the factors contributing to the fixation of bone-anchored implants, especially with regard to surface chemistry, surface topography and implant loading. The methodology used in the thesis ranges from systematic bench studies, computer simulations, experimental in vivo studies, to load cell measurements on patients treated with bone-anchored amputation prostheses.

  4. 12. Progression and treatment of experimental peri-implantitis

    Author : Jean-Pierre Albouy; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal experiment; bone loss; dental implants; histology; infection; inflammation; ICT; inflammatory lesion; peri-implant disease; peri-implantitis; plaque; radiographs; titanium; treatment;

    Abstract : Peri-implantitis is characterized by inflammatory lesions in peri-implant tissues and loss of supporting bone. The aims of the present series of studies were to analyze (i) spontaneous progression and (ii) the effect of surgical treatment of experimental peri-implantitis at different types of implants. Labrador dogs were used. READ MORE

  5. 13. Defining the clinical usefulness of vertebral fracture assessment

    Author : Lisa Johansson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vertebral fracture; vertebral fracture assessment; osteoporosis; DXA; HRpQCT; bone microindentation; mild vertebral fracture; physical function; fracture risk; incident fracture; older women;

    Abstract : Objective: Vertebral fractures (VFs) are the most common osteoporotic fracture and among the strongest predictors for future fracture. VFs can be identified by vertebral fracture assessment (VFA) from lateral spine imaging (LSI) by dual-energy X-ray absorptiometry (DXA). READ MORE

  6. 14. Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

    Author : Danfeng Cao; Edwin Jager; Jose Gabriel Martinez Gil; Jonathan Rossiter; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The human body is a complex system, consisting of different types of biomolecules and living matters, such as nucleic acids, proteins, carbohydrates, lipids, serum, cells, tissues, and organs. These complex biomolecules and living matters integrate and interact dynamically to perform and maintain body functions. READ MORE

  7. 15. Predictors of bone fragility in older women. Associations in older women between risk medications and measurements of physical function, bone microstructure and fracture risk

    Author : Berit A M Larsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteoporosis; risk prediction; fracture; risk medication; selective serotonin reuptake inhibitors; statins; physical function; timed up and go; one leg standing test;

    Abstract : Bone fragility with fractures constitutes a growing public health concern, resulting in suffering and major health care cost. This thesis project has been carried out by means of studies based on the SUPERB cohort of 75–80-year-old women from Gothenburg. READ MORE
