    Direct ink writing (DIW) techniques open up new possibilities for the fabrication of patient-specific bone grafts. Self-setting calcium phosphate inks, which harden at low temperature, allow obtaining nanostructured scaffolds ...
  • Bioceramics and bone healing 

    Ginebra Molins, Maria Pau; Español Pons, Montserrat; Maazouz, Yassine; Bergez, Victor; Pastorino Carraz, David (2018-05-01)
    Article
    Open Access
    - Calcium phosphates have long been used as synthetic bone grafts. Recent studies have shown that the modulation of composition and textural properties, such as nano-, micro- and macro-porosity, is a powerful strategy to ...
  • Cementos de fosfato tricálcico sustituidos con silicio: estudio de la bioactividad y de la liberacion de iones 

    Maazouz, Yassine (Universitat Politècnica de Catalunya, 2010-02)
    Master thesis (pre-Bologna period)
    Open Access
    El presente proyecto, que estudia un cemento de fosfato de calcio dopado con silicio y lo compara con el cemento análogo sin dopar, se divide en dos partes. En la primera, se evalúa la bioactividad de ambos cementos in ...
  • Evaluation of a porosity measurement method for wet calcium phosphate cements 

    Ajaxon, Ingrid; Maazouz, Yassine; Ginebra Molins, Maria Pau; Ohman, Caroline; Persson, Cecilia (2015)
    Article
    Open Access
    Covenantee:  Uppsala universitet
    The porosity of a calcium phosphate cement is a key parameter as it affects several important properties of the cement. However, a successful, non-destructive porosity measurement method that does not include drying has ...
  • Osteogenesis by foamed and 3D-printed nanostructured calcium phosphate scaffolds: Effect of pore architecture 

    Barba, Albert; Maazouz, Yassine; Díez Escudero, Anna; Español Pons, Montserrat; Montufar Jiménez, Edgar Benjamin; Ginebra Molins, Maria Pau (Elsevier, 2018-10-01)
    Article

    There is an urgent need of synthetic bone grafts with enhanced osteogenic capacity. This can be achieved by combining biomaterials with exogenous growth factors, which however can have numerous undesired side effects, but ...
  • Osteoinduction by foamed and 3D-printed calcium phosphate scaffolds: effect of nanostructure and pore architecture 

    Barba Serrahima, Albert; Díez Escudero, Anna; Maazouz, Yassine; Rappe, K.; Español Pons, Montserrat; Montufar Jiménez, Edgar Benjamin; Bonany Mariñosa, Mar; Sadowska, Joanna Maria; Guillem Martí, Jordi; Ohman, Caroline; Persson, Cecilia; Manzanares, Maria Cristina; Franch Serracanta, Jordi; Ginebra Molins, Maria Pau (2017-12-06)

    Some biomaterials are osteoinductive, that is, they are able to trigger the osteogenic process by inducing the differentiation of mesenchymal stem cells to the osteogenic lineage. Although the underlying mechanism is still ...
  • Relevance of the setting reaction to the injectability of tricalcium phosphate pastes 

    Ginebra Molins, Maria Pau; Montufar Jiménez, Edgar Benjamin; Maazouz, Yassine (2013-04-09)
    Article
    Open Access
    The ai m of the present work was to analyze the influence of the setting reaction on the injectability of tricalcium phosphate (TCP) pastes. Even if the injection was performed early after mixing powder and liquid, ...
  • Robocasting of biomimetic hydroxyapatite scaffolds using self-setting inks 

    Maazouz, Yassine; Montufar Jiménez, Edgar Benjamin; Guillem Martí, Jordi; Fleps, I.; Ohman, C.; Persson, C.; Ginebra Molins, Maria Pau (Royal Society of Chemistry, 2014-01-01)
    Article
    Open Access
    Low temperature self-setting ceramic inks have been scarcely investigated for solid freeform fabrication processes. This work deals with the robocasting of alpha-tricalcium phosphate/gelatine reactive slurries as a bioinspired ...
  • Self-hardening and thermoresponsive alpha tricalcium phosphate/pluronic pastes 

    Maazouz, Yassine; Montufar Jiménez, Edgar Benjamin; Malbert, Julien; Español Pons, Montserrat; Ginebra Molins, Maria Pau (2017-02)
    Article
    Open Access
    Although calcium phosphate cements (CPCs) are used for bone regeneration in a wide range of clinical applications, various physicochemical phenomena are known to hinder their potential use in minimally invasive surgery or ...
  • A study of the rheological properties and injectability of calcium phosphate cements : application to minimally invasive surgical procedures and scaffold fabrication for tissue engineering through rapid prototyping 

    Maazouz, Yassine (Universitat Politècnica de Catalunya, 2018-10-15)
    Doctoral thesis
    Open Access
    The present work addresses two different applications enabled by a specific and useful property of calcium phosphate cements (CPCs): injectability. On the one hand minimally invasive procedures involving the use of CPCs ...
  • Vertical bone regeneration with synthetic biomimetic calcium phosphate onto the calvaria of rats
