Accelerated hardening of nanotextured 3D-plotted self-setting calcium phosphate inks
(Elsevier, 2018-01-01)
Article
Open AccessDirect 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
(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
(Universitat Politècnica de Catalunya, 2010-02)
Master thesis (pre-Bologna period)
Open AccessEl 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 ... -
Computed tomography and histological evaluation of xenogenic and biomimetic bone grafts in three-wall alveolar defects in minipigs
(2021-05-01)
Article
Open Access
Covenantee: Mimetis Biomaterials / Universitat Internacional de Catalunya / Universitat de Barcelona. Departament de Patologia i Terapèutica ExperimentalObjectives This study aimed to compare the performance of a xenograft (XG) and a biomimetic synthetic graft (SG) in three-wall alveolar defects in minipigs by means of 3D computerised tomography and histology. Materials ... -
Evaluation of a porosity measurement method for wet calcium phosphate cements
(2015)
Article
Open Access
Covenantee: Uppsala universitetThe 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
(Elsevier, 2018-10-01)
Article
Open AccessThere 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
(2017-12-06)
Article
Open Access
Covenantee: Universitat Autònoma de Barcelona. Departament de Medicina i Cirurgia Animal / Universitat de Barcelona. Departament de Patologia i Terapèutica ExperimentalSome 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 ... -
Regeneration of segmental defects in metatarsus of sheep with vascularized and customized 3D-printed calcium phosphate scaffolds
(Nature, 2020-04-27)
Article
Open AccessAlthough autografts are considered to be the gold standard treatment for reconstruction of large bone defects resulting from trauma or diseases, donor site morbidity and limited availability restrict their use. Successful ... -
Relevance of the setting reaction to the injectability of tricalcium phosphate pastes
(2013-04-09)
Article
Open AccessThe 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
(Royal Society of Chemistry, 2014-01-01)
Article
Open AccessLow 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
(2017-02)
Article
Open AccessAlthough 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
(Universitat Politècnica de Catalunya, 2018-10-15)
Doctoral thesis
Open AccessThe 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 ... -
Use of three-dimensionally printed ß-tricalcium phosphate synthetic bone graft combined with recombinant human bone morphogenic protein-2 to treat a severe radial atrophic nonunion in a Yorkshire terrier
(Wiley, 2020-07-08)
Article
Open Access
Covenantee: Universitat Autònoma de BarcelonaObjective: To describe a novel surgical approach to treat a critical-sized bone defect due to severe, radial atrophic nonunion in a miniature dog. Study design: Case report Animal: A 1-year-old Yorkshire terrier with a ... -
Vertical bone regeneration with synthetic biomimetic calcium phosphate onto the calvaria of rats
(2019-01-18)
Article
Open Access
Covenantee: Inserm / University of Minnesota School of DentistryBone regeneration is often required to provide adequate oral rehabilitation before dental implants. Vertical ridge augmentation is the most challenging of all situations, and often requires the use of autologous bone ...
