Various types of metals have been used in dentistry, since ages. The properties, manufacturing process, reaction within the oral cavity are to be studied by the clinician to decide a treatment for the patient. Alloys are made of two or more metals. The basis of mixing two metals is to obtain a product that has improved properties, ideal for utilization. Alloys are used as filling materials like amalgam. They are used for all-metal fixed partial denture casting; metal sub-structure for ceramic-veneered fixed partial denture casting;removable partial denture framework casting; in implant body, fixture, component fabrication by manufacturer. The most commonly used alloy now is cobalt-chromium-nickel alloy. This article is a short overview about some commonly used alloys and their applications such as silver-palladium, cobalt-chromium, cobalt-chromium-nickel and also titanium alloys. These are a few among the various alloys formulated. A thorough knowledge about these materials and their properties are necessary by the clinician to obtain a desired outcome. This article shall also highlight the new trends being observed in alloy selection.
