Corrosion 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 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 کاملGalvanic Corrosion Behavior of Dental Alloys
There is a wide variety of dental alloys, ranging from nearly pure gold and conventional gold-based alloys to alloys based on silver, palladium, nickel, cobalt, iron, titanium, tin, and other metals (Table 1). The types of dental alloys have increased significantly since 1980s in order to change the market price of gold and palladium. Although gold alloys are the mate‐ rials of choice in this a...
متن کاملTarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys
Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...
متن کاملThe effect of repeated porcelain firings on corrosion resistance of different dental alloys
PURPOSE The aim of this study was to evaluate the effects of repeated porcelain firing process on the corrosion rates of the dental alloys. MATERIALS AND METHODS Cr-Co, Cr-Ni and Pd-Ag alloys were used for this study. Each metal supported porcelain consisted of 30 specimens of 10 for 7, 9 and 11 firing each. Disc-shaped specimens 10 mm diameter and 3 mm thickness were formed by melting alloys...
