A full metal crown is a type of dental restoration that covers the entire tooth surface and is actually really popular among the patients who require dental restoration service. It is made of metals, such as gold, palladium, platinum, or silver, or a combination of other non-precious alloys and is typically used to restore severely damaged teeth. A full metal crown may be recommended if a tooth has been significantly weakened by decay or fracture. A full-cast metal restoration is extremely durable and can be a good option for patients with severely damaged posterior teeth. It’s also exceptional when a full-cast fixed dental bridge is needed.

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 crowns 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, chewing forces, and are durable as well.  

Full Semi-Precious White is a type of full metal crown which has around 25% of noble metals content in it and which does not require gold, instead uses silver, palladium, and others. Their corrosion resistance is slightly lower than HN alloy but the costs are less than NH alloy. They can be used for crown or bridges with or without porcelain covering as well. These crowns generally fall into the noble or non-noble categories and have a metallic appearance. Base metal crowns have a lot of similarities to gold crowns but are lighter in weight while being a little harder and more resistant to wear.

Full Semi-Precious White restoration is extremely unlikely to break and also can be suitable for patients having badly damaged teeth and even when a full-cast fixed dental bridge is required. During its preparation it is necessary to prepare all axial walls and the occlusal surface which helps in providing greater retention than opting for a conservative restoration on the same tooth. They can be highly biocompatible. Metal alloys have extremely good biocompatibility with gingival tissue and are unlikely to promote any allergic reactions. They are not susceptible to accumulating plaque, offer good corrosion resistance, and do not absorb fluids as well. It has numerous other advantages which includes:-

• They are durable.
• They are cost-efficient.
• They are highly resistant to deformation.
• Axial tooth contour modification is possible.
• They are conservative.
• They are highly biocompatible.
• They are corrosion-resistant and do not absorb fluids.
• They reduce the concern of wearing the opposite teeth.
• The coefficient of expansion is similar to natural teeth.
• They reduce the risk of excessive wear.

Although Full Semi-Precious White restoration has a number of advantages they do have some limitations with them. Some of them are mentioned below:-

• They may interfere with taste.
• They may not be aesthetic and look unreal.
• They require extensive tooth structural removal.
• They are not suitable for the ones who have metal allergies.
• They might cause a gum recession.

When selecting a dental restoration, it is important to think about the material. Metal crowns are really durable as they rarely chip or break, and non-precious crowns are a good option for people on a budget. If you’re looking for something more unique, consider a Full Semi-Precious White crown.
