      In oral orthodontic treatments, achievement of a good adhesion between brackets and teeth surfaces is essential. One way to increase adhesion is to apply a surface treatment of teeth facing surfaces through the ...

    • Influence of different CoCrMo counterfaces on wear in UHMWPE for artificial joints 

      González-Mora, V. A.; Hoffmann, Michael; Stroosnijder, R.; Espinar, Eduardo; Llamas, José María; Fernández-Fairén, Mariano; Gil Mur, Francisco Javier (Springer, 2011)
      Article
      Accés obert
      Wear tests were carried out to study the effect of various counterface materials in the wear behaviour of Ultra High Molecular Weight Polyethylene (UHMWPE). The materials used as counterfaces were based on varieties of ...

    • Reduction of Ni release and improvement of the friction behaviour of NiTi orthodontic archwires by oxidation treatments 

      Espinar, Eduardo; Llamas, José María; Michiardi, Alexandra; Ginebra Molins, Maria Pau; Gil Mur, Francisco Javier (2011-03-25)
      Article
      Accés restringit per política de l'editorial
      This work studies NiTi orthodontic archwires that have been treated using a new oxidation treatment for obtaining Ni-free surfaces. The titanium oxide on the surface significantly improves corrosion resistance and decreases ...

    • Variation of the superelastic properties and nickel release from original and reused NiTi orthodontic archwiresOriginal 

      Gil Mur, Francisco Javier; Espinar, Eduardo; Llamas, José María; Manero Planella, José María; Ginebra Molins, Maria Pau (2012)
      Article
