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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Integrated biomechanical, electronic and topographic characterization of titanium dental implants

    Författare :Johanna Löberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface roughness parameters; 3D-SEM; AFM; Interfacial shear strength; Impedance spectroscopy; Cyclic voltammetry; SBF; MG-63; TiO2-nanoparticles;

    Sammanfattning : Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored in the bone to withstand the forces induced by for example chewing. LÄS MER

  4. 3. Surface characterization methods for quality assessment of polyethylene-coated paperboard

    Författare :Javier Mauricio Brugés; Jan Lundgren; Mattias Andersson; Mikael Sjödahl; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization; surface characterization; Stokes polarimeter; polyethylene coating; paperboard;

    Sammanfattning : In manufacturing processes, the quality of a product often depends on its surface, and careful control of surface properties is critical to meet customer requirements. A thin layer of polyethylene (PE) is applied to paperboard to increase barrier functionality and high optical quality of the product. LÄS MER
