Study of the Influence in osteoblastic Behavior of compressive residual Stress in smooth and rough Surfaces of titanio dental Implants. (Tesis Doctoral Inédita). Universidad de Sevilla, Sevilla.https://hdl.handle.net/11441/164816In oral rehabilitation, the necessity of excellent results in long term, translated in a physiologic fully adapted masticatory function and irrepressible aesthetics, totally satisfactory to individual requirements, become the ultimately and principal objective to the surgical and dental clinician. Nowadays, the use of dental implants in oral rehabilitation have become an usual process with predictable results. All the efforts to improve the biological relationship of these materials with the host, have allowed the rehabilitation of cases with increasing complexity. All the process of conceptualization and execution of the rehabilitation treatment is based in an well adapted individual plan. The treatment clinical decision must be supported on broad and enlightened knowledge of the available instruments. The evolution of dental implants, and changes resulting from this, has followed a line towards optimizing the relationship of these devices with neighboring tissues, namely with the surrounding bone, through osseointegration process, and with soft tissues maintaining their integrity. In this sense, implant surface treatments concerning the topography, chemical composition and surface energy have made possible to enhance these results making the osseointegration process faster, more effective and predictable. Surface treatments can be categorized as additive, subtractive or bioactive. Many of these treatments are carried out in a combined way, enhancing the added value of each one. It is generally agreed that the topographical change of an implant through these treatments will consequently bring a chemical change to the surface of the implants. The surface energy and wettability inherent to the material also change, which, in terms of osteointegration, becomes an added value in being able to enhance the relationship between the implant and the biomolecular environment, since these energetic properties may increase adhesion, proliferation and cell differentiation. It is known that subtraction treatments change the residual energy of materials. The effect that this energetic alteration promotes at the molecular, cellular and bacteriological level is still an open field whose knowledge and comprehension may enhance the results to obtain. The aim of this work is to establish a relationship between two titanium surfaces, rough and smooth, and the residual energy on each one of these surfaces with the adhesion, proliferation and differentiation of osteoblastic cells, as well as understanding whether there is a relationship between this residual energy and the development of bacterial species present in the oral cavity, using two colonizing species with different characteristics.149 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccess
