Special Issue Information

Dear Colleagues,

Titanium and its alloys are important modern materials used for a variety of applications, in aeronautics, the automotive industry, extreme sports, and biomedical engineering. Commercially pure grades of titanium are commonly used in dentistry, after specific anodic surface treatments. As a transition metal, titanium serves to produce two-, three-, and four-component alloys, with favorable increased strengths and corrosion resistance. Plasma electrolytic oxidation (PEO) processes are developed to improve the surface of titanium alloys which serve for the production of joint endoprosthetics, elements for joining bone fractions, components of heart valves and artificial hearts in cardiac surgery and interventional cardiology, and for medical instrumentation.

Currently used electrochemical treatments such as PEO, known also as micro-arc oxidation (MAO) processes, serve to modify titanium and its alloys. A variety of surface properties are achieved thanks to the introduction of expected elements and compounds into the fabricated coatings of mono- or multi-layer structure. Porous coatings formed on the metal surface are fabricated for their biocompatibility and non-toxicity, with bactericidal properties, and may exhibit hydrophilic or hydrophobic properties.

This Special Issue is devoted to displaying the recent advances and achievements in the field. Specifically, modern electrochemical treatment methods to control the composition of the surface layer, its structure, and its properties on request are a focus.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Porphyromonas gingivalis infection is one of the causes of implant failures, which can lead to peri-implantitis. Implant surface roughness is reportedly related strongly to P. gingivalis adhesion, which can lead to peri-implantitis and, later, cell adhesion. Our aim was to evaluate the effects of Er,Cr:YSGG laser on titanium (Ti) disc surfaces and its interaction with bacterial adhesion and fibroblast viability. Ti discs underwent two treatments: autoclaving (control) and erbium, chromium-doped yttrium scandium gallium garnet (Er,Cr:YSGG) laser treatment (test). Ti disc surfaces were examined with scanning electronic microscope (SEM), Energy-dispersive spectrometry (EDX), X-ray photoelectron spectroscopy (XPS). The surface roughness same as wettability were also investigated. Fibroblast viability was assessed with the water-soluble tetrazolium 1 (WST-1) test, and osteoblast differentiation was assessed with the alkaline phosphatase (ALP) assay. Bacterial structure and colony formation were detected with scanning electron microscopy and Gram stain. In comparison to control discs, the test discs showed smoother surfaces, with 0.25-µm decrease in surface roughness (p < 0.05); lower P. gingivalis adhesion (p < 0.01); less P. gingivalis colonization (p < 0.05); and increased fibroblast viability and osteoblast differentiation (p < 0.05). Er,Cr:YSGG laser treatment improved disc surfaces by making them slightly smoother, which reduced P. gingivalis adhesion and increased fibroblast viability and osteoblast differentiation. Er,Cr:YSGG laser treatment can be considered a good option for managing peri-implantitis. Further investigations of laser-assisted therapy are necessary for better guidelines in the treatment of peri-implantitis. Full article
