Effects of chemical composition on the corrosion of dental alloys.
The aim of this study was to determine the effect of the oral environment on the corrosion of dental alloys with different compositions, using electrochemical methods. The corrosion rates were obtained from the current-potential curves and electrochemical impedance spectroscopy (EIS). The effect of artificial saliva on the corrosion of dental alloys was dependent on alloy composition. Dissoluti...
متن کاملMechano-chemical stability of gold nanoparticles coated with alkanethiolate SAMs.
Molecular dynamics simulations are used to probe the structure and stability of alkanethiolate self-assembled monolayers (SAMs) on gold nanoparticles. We observed that the surface of gold nanoparticles becomes highly corrugated by the adsorption of the SAMs. Furthermore, as the temperature is increased, the SAMs dissolve into the gold nanoparticle, creating a liquid mixture at temperatures much...
متن کامل[Dental alloys and corrosion].
Jedan od osnovnih zahteva koji se postavlja za sve stomatološke materijale jeste da su neškodljivi za ljudski organizam i (primum non nocere) i zatim da ne deluju nadražajno ili toksičko na oralna tkiva i organizam u celini. Oni takođe moraju biti niske alergijske aktivnosti i bez štetnog delovanja na bolesnike i osoblje koje njima rukuje. Stomatološke nadoknade ostaju u ustima dug vremenski pe...
متن کاملCorrosion Resistance of Dental Alloys
Metals and metallic alloys are unavoidable materials in everyday dental use for the making of fillings, cast cores and post systems, individual crowns, implantants’ suprastructures, dentures and orthodontic devices. They still belong to the vital materials in dentistry. Applied alloys in a mouth are exposed to the influence of chemical, biological, mechanical, thermal and electrical forces whic...
متن کاملGrindability of dental magnetic alloys.
In this study, the grindability of cast magnetic alloys (Fe-Pt-Nb magnetic alloy and magnetic stainless steel) was evaluated and compared with that of conventional dental casting alloys (Ag-Pd-Au alloy, Type 4 gold alloy, and cobalt-chromium alloy). Grindability was evaluated in terms of grinding rate (i.e., volume of metal removed per minute) and grinding ratio (i.e., volume ratio of metal rem...
