MECHANICAL PROPERTIES AND STRUCTURAL RELIABILITY
The group specialises in the mechanical behaviour, reliability and the relationship between microstructure and in-service behaviour of a wide range of advanced materials. For example, it studies the biomechanical behaviour of different commercial structural prostheses in order to replace the materials from which they are made with new materials that are more reliable, durable and at the same time multifunctional. This last research line is based on the basic knowledge acquired in the field of biomaterials to transfer it to a real clinical problem.
The research lines currently focus on the study of:
– Ceramic materials, composites and ceramic matrix nanocomposites.
The scientific objective is the development of ceramic materials with high reproducibility and mechanical reliability. In this sense, research focuses on the study of different monolithic materials such as eco-piezoceramics subjected to an electric field or ceramics with dual microstructures, which are two-phase materials in which their components have different properties such as the coefficient of thermal expansion or the elastic modulus, or dissimilar composite materials such as ceramic-metal composites. This anisotropy in their properties and/or composition can be used to produce an increase in toughness by means of shielding mechanisms that make these types of materials tolerant to defects. Likewise, laminated structures of both the ABAB type and with gradient function are being developed. In this type of macrostructures, an optimal stress distribution can be obtained in order to increase their structural reliability. In all these cases, a vitally important aspect is the study of their cyclic fatigue, i.e. under subcritical conditions, since it is under these conditions that the components formed by these types of materials are generally going to work.
– Materials and components for dental implantoprostheses
Nowadays, the problems related to dental implants, in which this line of research is included, have an extraordinary impact both from a social point of view (in the EU alone the number of people who need implants is more than 100 million) and from an economic point of view. It is a sector with a spectacular growth (>20% per year), reaching a volume of € 5000 million in the EU alone. The results of this line have led to the development of a new generation of biomaterials for use in dental applications with a higher success rate than current implants. This is due to a lower number of clinical failures both biological, mainly associated with the reduction of the accumulation of dento-bacterial plaque that causes infections and/or peri-implantitis (20% of the population is prone to this disease), and biomechanical, as these new materials with improved mechanical properties can withstand higher levels of load applied to the implant. To this end, we have worked with dentists, mainly from the UCM, and with different leading companies in the dental sector (Straumann, Zimmer, etc…) to evaluate commercial implants and their possible improvements.
– Biomechanics of vertebral prostheses
This line of research is being focused in the field of cervical and spinal implantology, in collaboration with hospitals (e.g. Hospital Clínico Universitario de Valencia, Hospital de Villalba de Madrid, etc.) and companies (e.g. Spineart). Biomechanical studies of the implants are carried out, which, together with clinical studies, show the critical dependence of the clinical success of this type of implants on the materials of which they are made. The ultimate aim of all this research is to replace the current materials used in prosthetic components that present major durability problems (breakage or wear), infections or diagnostic problems (artefacts generated using the NMR technique) with new materials developed in this line of research.
