    • Optimización del proceso de Nanocavitación para superficies rugosas de Titanio y estructuras 3D 

      Aguilar Caparrós, Manel (Universitat Politècnica de Catalunya, 2024-07-03)
      Bachelor thesis
      Open Access
      Les modificacions superficials a escala nanomètrica s'utilitzen ampliament per millorar la biocompatibilitat de materials per implants. En aquest estudi es vol optimitzar el procès químic nomenat Nanocavitació, que genera ...

    • Optimization of a thermochemical process and antibacterial properties for 3D printed prostheses of titanium 

      Rafik Rafik, Belal (Universitat Politècnica de Catalunya, 2019-02-25)
      Master thesis
      Restricted access - author's decision

      A relevant aspect in the biomedical field is the research for optimizing the bone-implant coupling in order to avoid the stress-shielding effect. Bone requires a mechanical stimulus for growth; hence, in a bone-implant ...

    • Osteointegration characterization of titanium biofunctionalized with drug-loaded nanoparticules implanted in a diabetic animal model 

      Hulata, Elise (Universitat Politècnica de Catalunya, 2022-02-08)
      Master thesis
      Open Access
      Type II diabetes mellitus is the most common metabolic disorder and represents a contraindication for optimal orthopaedic implant treatment since it is considered to be directly related to decrease bone regeneration ...

    • Prótesis total de cadera con disco a compresión (PDC) 

      Merino, E. J.; Higuera, J.; López Acevedo, G.; Prieto, J. M.; Ramos, M. (Sociedad Ibérica de Biomecánica y Biomateriales, 1997)
      Article
      Open Access
      Se describe en este trabajo, un implante protésico total no cementado de cadera, sin anclaje intramedular. Se estudia la biomecánica de la articulación de la cadera, de los implantes endomedulares y se marcan las ...

    • Silver nanoparticles deposition on titanium surface through silanization 

      Moreno Duarte, Daniel; Rodríguez Rius, Daniel; Manero Planella, José María (Universitat Politècnica de Catalunya, 2022-06-16)
      Conference lecture
      Open Access

    • Surface treatment of titanium with antibacterial properties for biomedical applications 

      Chihab, Nahel (Universitat Politècnica de Catalunya, 2021-02-15)
      Master thesis
      Open Access
      Titanium, thanks to its good mechanical properties and an excellent biocompatibility and osseointegration, is used in the manufacture of dental implants. Nevertheless, after insertion into the human body, ...

    • Titanium scaffolds by direct ink writing: Fabrication and functionalization to guide osteoblast behavior 

      Rupérez de Gracia, Elisa; Vidal Girona, Elia; Rodríguez Rius, Daniel; Guillem Martí, Jordi; Ginebra Molins, Maria Pau; Manero Planella, José María; Torres Garrido, Diego; Scionti, Giuseppe (Multidisciplinary Digital Publishing Institute (MDPI), 2020-08-27)

      Titanium (Ti) and Ti alloys have been used for decades for bone prostheses due to its mechanical reliability and good biocompatibility. However, the high stiffness of Ti implants and the lack of bioactivity are pending ...

    • Tribological behavior of surface nitrided zirconia 

      Puaud, Margerie (Universitat Politècnica de Catalunya, 2009-02)
      Master thesis (pre-Bologna period)
      Open Access
      Since the middle of the 80’s, zirconia stabilized with yttrium oxide (Y-TZP) is used in order to produce femoral heads. This material shows a reinforcement mechanism by phase transformation that provides excellent mechanical ...

    • Zirconia vs. titanium dental implants: primary stability in-vitro analysis 

      Arlucea, Nerea; Brizuela Velasco, Aritza; Diéguez Pereira, Markel; Punset Fuste, Miquel; Molmeneu Trias, Meritxell; Sánchez Lasheras, Fernando; De Llanos Lanchares, Hector; Álvarez Arenal, Ángel (Multidisciplinary Digital Publishing Institute (MDPI), 2021-12-20)
