Full metal crowns are one type of dental crowning which are really on the hype in the market. This kind of metal crowning is made up of several types of metal including gold, palladium, nickel, chromium, and a combination of other non-precious alloys. Metal crowns give a full crown covering all axial surfaces of the tooth and are one of the commonly indicated crown restorations for posterior teeth. As they are made of metal, they are mostly preferred by people who don’t mind the appearance of metal and can be used as a single unit. There are various types of full metal crowning available for you to choose from according to your preference which includes ​Full Non-Precious, Full Semi-Precious White, Full Semi-Precious Yellow, Full White High-Noble, Full Yellow High-Noble, Inlay/Onlay Yellow High-Noble,  NP Post & Core, SP Post & Core. Metal crowns are really durable as they rarely chip or break, and non-precious crown require only a very minimum amount of the tooth to be prepared to preserve the core for maximum strength and retention than other types of crownings. PFM non-precious crowns can endure biting, hewing forces, and are durable as well.  

Full Non Precious metals are also referred to as base metal alloys and when compared to noble or precious metals they are more abundant in nature. This is the reason why they are a bit cheaper in comparison. Full Non Precious restoration is suitable for thoses who require  posterior restorations, patients with heavy bite/tight occlusion. Compared to any other noble metals they are relatively more reactive to the atmosphere and will oxidize, tarnish and corrode relatively easily when exposed to moisture, air or acidity. Full Non Precious metals are produced with the combination of more than around 75% base metals, and a limited noble metal content including gold and platinum group metals of less than 25%. Even nickel free alloy can be used in case a patient has any kind of allergies. And for patients who have an allergy with nickel the alloy used is cobalt chromium (Nickel free) which is silver in color.
