[Initial corrosion of dental casting alloys in the oral environment].
In order to study the initial corrosive changes of dental casting alloys in the mouth, the condition and composition of the proximal surface of the class II inlay were analyzed by the scanning electron microscope (SEM) and the electron probe microanalyser (EPMA). These analyses on the same small areas of the proximal surface were carried out every week for four weeks. The results were compared ...
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 کامل“An investigation of the corrosion characteristics of base ceramo-metal dental casting alloys"
Ceramo-metal dental casting alloys are used for crowns and fixed partial dentures (bridges). Ni-Cr and Co-Cr are base ceramo-metal dental casting alloys and now account for the majority of the fixed metalceramic restorations used clinically. The corrosion of these alloys result in release of elemental components with potential adverse biological reactions. It is of great importance to investiga...
متن کاملCasting of Titanium Alloys for Dental Applications
In dentistry, gold-based noble metal alloys have traditionally been cast into various types of dental prostheses, such as partial dentures, crowns, and bridges. More recently, less expensive dental alloys with base-metal elements, such as Co-Cr and Ni-Cr, have been used. Titanium is considered to be an attractive alternative to these traditional dental alloys because of its remarkable lack of t...
