  2. 1. 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.

  6. 4. Characterising Dental Implant Surfaces by Topographical, Electrochemical, and Biomechanical Methods

    Author : Johanna Löberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium dental implants; 3D-SEM; AFM; Mott-Schottky analysis; surface roughness parameters; biomechanics.;

    Abstract : Replacement of extracted teeth by dental implants was first introduced in the 1950’s. From the beginning, threaded titanium implants with smooth surfaces were used. Later on, screw shaped implants with micro-scaled roughened surfaces were introduced showing bone ingrowth and improved in vivo and in vitro results and good long term stability. READ MORE

  7. 5. Bone structure characterisation using neutron scattering techniques

    Author : Elin Törnquist; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanics; neutron tomography; x-ray tomography; small-angle neutron scattering SANS ; small-angle x-ray scattering SAXS ; Experimental mechanics; implant integration; tomography; nanoscale; microscale; mechanical properties;

    Abstract : Bones have unique mechanical properties that originate from their main constituents: mineral, in the form of hydroxyapatite (HAp) crystals, and collagen type-I. The stiffness of the HAp mineral combined with the flexibility of collagen, and their intricate hierarchical arrangement from the smallest individual building blocks to the organ level, result in a composite tissue with a remarkable ability to withstand complex loading scenarios.
