Special Issue Information

Dear Colleagues,

Advanced materials (e.g.,: ceramic, metallic, and metallic alloy materials), post-processing techniques (e.g., anodizing, physical, or chemical vapor deposition, etc.), and/or surface modification strategies (e.g., chemical etching, laser patterning, etc.) have gained interest within the field of biomedical applications over the last years, particularly for dental implants.

In this regard, an improved knowledge of these advanced materials, as well as the post-treatment surfaces of them and the correlation between the microstructure, corrosion resistance, and biocompatibility properties will lead to hierarchical design materials, ranging across length scales over several orders of magnitude (i.e., from nanometers to hundreds of centimeters), depending the post-processing technique used.

Based on these considerations, this Special Issue aims to provide a critical overview of the current post-processing techniques and surface modification strategies for advanced materials, investigating and comparing the changes produced by these treatments in terms of microstructure, aging, and corrosion resistance, and the biological performance for dental implants. Furthermore, research articles, reviews, and communications relating to this topic, thus leading to developments in the design of advanced biomaterials for both material science researchers and practicing engineers and dentists, are all invited for this Special Issue.

You may choose our Joint Special Issue in Metals.

This study investigates the thermal stability and microstructural evolution of the solid electrolyte medium used in DLyte® dry electropolishing and dry anodizing processes. Samples were thermally aged between 30 °C and 45 °C to simulate Joule heating during industrial operation. Visual and SEM analyses revealed shape deformation and microcrack formation at temperatures above 40 °C, potentially reducing particle packing efficiency and electrolyte performance. Particle size distribution shifted from bimodal to trimodal upon aging, with an overall size reduction of up to 39.5% due to dehydration effects, impacting ionic transport properties. Weight-loss measurements indicated a diffusion-limited dehydration mechanism, stabilizing at 15–16% mass loss. Fourier transform infrared analysis confirmed water removal while maintaining the essential sulfonic acid groups responsible for ionic conductivity. In dry anodizing tests on titanium, aged electrolytes enhanced process efficiency, producing TiO2 films with improved optical properties—color and brightness—while preserving thickness and uniformity (~70 nm). The results highlight the need to carefully control thermal exposure to maintain electrolyte integrity and ensure consistent process performance. Full article
