Noble and high-noble alloys used in casting crowns are generally based on alloys of gold. Gold is not used in its pure form as it is too soft and has poor mechanical strength. Other metals included in gold alloys are copper, platinum, palladium, zinc, indium and nickel.
This was the first material that truly replaced the usage of noble alloys in Orthodontics. Steel wire alloys, in comparison to the noble metals, were relatively cheaper. They also had better formability and can be readily used to be soldered and welded for fabrication of complex orthodontic appliances. [3]
Cobalt-chrome disc with dental bridges and crowns manufactured using WorkNC Dental. Cobalt-chrome or cobalt-chromium (CoCr) is a metal alloy of cobalt and chromium.Cobalt-chrome has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants.
An amalgam dental filling. Dentistry has used alloys of mercury with metals such as silver, copper, indium, tin and zinc. Amalgam is an "excellent and versatile restorative material" [9] and is used in dentistry because it is inexpensive and relatively easy to use and manipulate during placement.

A three unit porcelain fused to metal bridge (PFM) made by a dental technician A semi-precision attachment between teeth #3 and #4, with the mortise on #4. Note the lingual buttons extending, in the photo, upward on #2 (on the left) and downward on #4.
In dentistry, an abutment is a connecting element. [1] This is used in the context of a fixed bridge (the "abutment teeth" referring to the teeth supporting the bridge), partial removable dentures (the "abutment teeth" referring to the teeth supporting the partial) and in implants (used to attach a crown, bridge, or removable denture to the dental implant fixture).
The metal can be melted using either gas and compressed air, gas and oxygen or electric arc. Casting methods include the use of steam pressure or a centrifugal system. Gold is an example of a material that can be used to produce inlays/onlays.
