  2. 16. On loading protocols and abutment use in implant dentistry. Clinical studies

    Author : Catharina Göthberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; abutment design; clinical studies; dental implants; dental prosthesis; implant-supported; gene expression; health; immediate implant loading; marginal bone loss; osseointegration; prosthodontics; risk factors; smoking; treatment outcome;

    Abstract : ABSTRACT Research questions: The influence of immediate or delayed loading and the use of abutments in implant dentistry with regard to peri-implant tissues and the effect of risk parameters. Methodology: Fifty partially edentulous patients each received three Brånemark TiUnite™ implants. READ MORE

  4. 17. A methodological platform to study molecular biocompatibility of biomaterials. Experimental and clinical studies

    Author : Maria Lennerås; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; inflammation; cell recruitment; cell adhesion; bone regeneration; bone remodelling; gene expression; immunohistochemistry; histomorphometry; removal torque; ultrastructure; FACS; protein profiling; transfemoral amputation; abutment; percutaneous; bacteria; clinical signs;

    Abstract : The aim of this project was to develop a methodological platform in order to advance our scientific understanding of the mechanisms of osseointegration. Screw-shaped, titanium implants, with different surface properties, were inserted in the rat tibia, or incubated in mono- or co-culture of human monocytes and MSCs. READ MORE

  5. 18. Multimodal and multiscale characterization of bone and bone interfaces in health and disease

    Author : Chiara Micheletti; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone; osseointegration; characterization; mineralization; ultrastructure; diabetes; osteoporosis; MRONJ; surface functionalization; local drug delivery; titanium; bioactive glass; imaging; spectroscopy; microscale; nanoscale; micro-computed X-ray tomography; micro-Raman spectroscopy; scanning electron microscopy; transmission electron microscopy; PFIB-SEM tomography; electron tomography;

    Abstract : Seeing is believing. Our understanding of phenomena often involves their direct observation. However, bone architecture is challenging to visualize given its multi-level hierarchical organization. READ MORE

  6. 19. Towards Natural Control of Artificial Limbs

    Author : Max Jair Ortiz Catalan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epimysial electrodes; robotic prostheses; sensory feedback.; real-time and simultaneous prosthetic control; neurostimulation; pattern recognition; advanced prosthetic control; neural interfaces; artificial limbs; cuff electrodes; bone-anchored prostheses; osseointegration;

    Abstract : The use of implantable electrodes has been long thought as the solution for a more natural control of artificial limbs, as these offer access to long-term stable and physiologically appropriate sources of control, as well as the possibility to elicit appropriate sensory feedback via neurostimulation. Although these ideas have been explored since the 1960’s, the lack of a long-term stable human-machine interface has prevented the utilization of even the simplest implanted electrodes in clinically viable limb prostheses.

  7. 20. Biomaterials for Promoting Self-Healing of Bone Tissue

    Author : Sonya Piskounova; Jöns Hilborn; Tim Bowden; Simon Cool; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Osseointegration; implant coating; hyaluronan hydrogel; bone morphogenetic protein-2; hydroxyapatite; bone; delivery system; injectable; mixing; radioactive labeling; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Abstract : The present work addresses poor bone/implant integration and severe bone defects. In both conditions external stimuli is required for new bone to form. READ MORE
