The biomimetic sealing of dental implants (BIOSELLADO)

Lead Researcher:
Daniel Rodríguez Rius

Research Centre:
Universidad Politécnica de Cataluña. Barcelona.


Daniel Rodríguez RiusThe objective of this project is to modify the surface of titanium according to biomimetic models, to reduce failures due to bacterial infections in dental implants (peri-implantitis). To this end, the aim is to achieve the biological sealing of the implant with oral tissue by means of anchoring sequences of adhesion for the cells of the gum tissue over a coating that is antiadhesive for bacteria, in combination with the biomimetic deposition of apatite on the surfaces in contact with the bone tissue, to improve osteointegration.

The effect of these modifications will be studied in vitro to evaluate the reduction in bacterial adhesion and growth on the treated surface, as well as to evaluate any possible effects on gingival cells and osteoblasts. Once the best treatments have been selected, they will be used on a type of implant in the respective areas of contact with the bone tissue and gingival tissue, and will be tested in vivo in an animal model.

Daniel Rodríguez Rius (Barcelona, 1971) is an Industrial Engineer and Doctor (Polytechnic University of Catalonia (UPC)). He is currently professor of the Materials Science and Metallurgical Engineering at the UPC, and is a member of the BIBITE research group (Biomaterials, Biomechanics and Tissue Engineering), where he is in charge of the Nanotechnology Biomaterials Group at the NanoEngineering Research Centre (CRnE). Another outstanding feature of his professional career is his experience as the Head of R&D in a company that manufactures medical products.

He has taken part in several applied and research projects in the field of Biomaterials and Medical Products. He is the author of dozens of papers published in scientific journals, and has made many contributions to national and international conferences. He is also the editor of Biomecánica, the official journal of the Iberian Biomaterials and Biomechanics Society (SIBB), and an active member of various scientific associations in the field of Biomaterials and Biomechanics.

His chief area of research is based on the development of new surface treatments to improve the interaction between biomaterial and live tissue, together with the application of nanotechnology to this field of research.
