      Concave surfaces have shown to promote bone regeneration in vivo. However, bone scaffolds obtained by direct ink writing, one of the most promising approaches for the fabrication of personalized bone grafts, consist mostly ...
    • Accelerated hardening of nanotextured 3D-plotted self-setting calcium phosphate inks 

      Raymond Llorens, Santiago; Maazouz, Yassine; Montufar Jiménez, Edgar Benjamin; Perez, Roman A.; González Arcos, Borja; Konka, Joanna Magdalena; Ginebra Molins, Maria Pau (Elsevier, 2018-01-01)
      Article
      Open Access
      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 ...
    • Computed tomography and histological evaluation of xenogenic and biomimetic bone grafts in three-wall alveolar defects in minipigs 

      Raymond Llorens, Santiago; Pastorino Carraz, David; Ginebreda, Ignacio; Maazouz, Yassine; Ortiz, Mònica; Manzanares, Maria Cristina; Ginebra Molins, Maria Pau (2021-05-01)

      Actual polymer bioresorbable stents (BRS) generate a risk of device thrombosis as a consequence of the incomplete endothelialization after stent implantation. The material-tissue interactions are not fully controlled and ...
    • Hydrothermal processing of 3D-printed calcium phosphate scaffolds enhances bone formation in vivo: a comparison with biomimetic treatment 

      Raymond Llorens, Santiago; Bonany Mariñosa, Mar; Lehmann, Cyril; Thorel, Emilie; Benítez Iglesias, Raúl; Franch Serracanta, Jordi; Canal Barnils, Cristina; Ginebra Molins, Maria Pau (Elsevier, 2021-11-01)
