Special Issue Information

Dear Colleagues,

Today's development of materials, and the development of nanotechnology and biocompatible materials in particular, has contributed to the emergence of better materials and procedures in medicine not only in the laboratory aspect but also in clinical use. Because of this, modern materials enable us to achieve better clinical success in treatment and better quality throughout the clinical period.

We have a large number of materials obtained through nanotechnology, with much better laboratory characteristics than older generation materials. Of particular note is the huge progress in composite materials for restorative dentistry, biocompatible materials for treatment and regeneration, new forms of dental ceramics and alloys, and, of course, huge progress in dental implantology. Osseointegrating materials enable bone and tissue replacement and, with biocompatible and advanced osteointegrating implants, solve the problems we had before. In order to significantly reduce the discrepancy between science and practice, the analysis of modern materials and treatment procedures between laboratory and clinical work is of crucial importance. Laboratory methods and results from the research of materials and their physical characteristics allow us to apply these same materials in clinical research, especially if it concerns biomedicine and related branches.

Therefore, I invite researchers of various professions involved in the clinical and laboratory analysis of modern materials and procedures in biomedicine and dentistry to contribute their scientific works to the advancement of science and technology so that we have better treatment methods to choose from.

Based on their high mechanical strength, Ti-based high-entropy alloys (HEAs) are of great potential as materials for high-performance reduced-diameter dental implants. Despite previous studies demonstrating their corrosion resistance in various simulated body fluids, their resistance in simulated buccal conditions has yet to be confirmed. In this work, the corrosion behavior of two Ti-based HEAs, TiZrHfNb, and TiZrHfNbTa was evaluated in comparison to CP-Ti and Ti-6Al-4V in artificial saliva (AS) solution and in AS with fluoride ion content (ASF). A set of electrochemical tests (electrochemical impedance spectroscopy, cyclic polarization, and Mott–Schottky) was employed and complemented with surface characterization analyses (scanning electron microscopy and atomic force microscopy) to determine dissolution and passivation mechanisms of the alloys. In general, the HEAs exhibited a far superior corrosion resistance compared to CP-Ti and Ti-6Al-4V alloys in both solutions. In the AS solution, the TiZrHfNb exhibited the highest polarization resistance and pitting potential, indicating a high corrosion resistance due to the formation of a robust passive layer. Whilst in the ASF solution, the TiZrHfNbTa showed a greater corrosion resistance due to the synergistic effect of Nb and Ta oxides that enhanced passive film stability. This finding emphasizes the role of Ta in elevating the corrosion resistance of Ti-based HEAs in the presence of fluoride ions and confirms the importance of chemical composition optimization in the development of next-generation dental alloys. Based on its electrochemical corrosion behavior, TiZrHfNbTa HEAs are promising new materials for high-performance reduced-diameter dental implants. Full article
