Porcelain Fused to Metal Crowns (PFM)
Advantages of porcelain fused to metal crowns
- The underlying metal fused with the porcelain provides stability and strength to the crown.
- It has great aesthetic appeal and is most commonly preferred as it gives the restored tooth a natural look.
- They have a very high rate of success in the long run.
PFM crowns are a hybrid between porcelain and metal crowns. Initially a metal shell is prepared which can fit perfectly over the concerned tooth. Then a porcelain veneer is fused on the metal shell which gives the crown a natural looking appearance. METAL DOES NOT SHOW AT ALL.
The best part of these crowns is the stability and strength which is unmatched to any other restorations available today.
- These are best for patients looking for natural look and durability.
- Porcelain fused to metal crowns (PFM) are highly recommended for back teeth restorations
- PFM crowns have been the commonest option for dentists as well as for patients for over 35 years
WHAT IS A DENTAL CROWN?
- A dental crown is a cap that is tooth shaped. It covers a particular tooth to re-establish its size, shape, appearance and improve its strength.
- When the crown is cemented, it completely encases the visible portion of the tooth.
- They look just like a natural tooth and last for about seven years. Sometimes, they last up to forty years
When is a dental crown needed?
- There are a number of conditions when crowning may be required. Some of them are:
- To protect any tooth from breakage or decay and in some cases to hold pieces of a cracked tooth together.
- To restore a broken tooth.
- To support and cover a tooth with an outsized filling in case a large part of the tooth is not available.
- To keep a dental bridge in its place.
- To cover up a tooth that is highly discolored.
- To cover up a dental implant.
Some typical use cases of dental crowns:
- In case of a cracked tooth resulting from chewing with excessive force, crowning becomes essential.
- A tooth which underwent root canal treatment may become weak and be more vulnerable to a fracture. Thus, it needs to be covered by a crown so that chances of fracture are minimized.
- When a tooth becomes fractured such that any filling cannot restore it then it has to be replaced with a crown.
A PORCELAIN FUSED TO METAL CROWN (PFM) is a preferred choice when bridges for the long run are required and night grinding is a problem. Since these crowns are a combination of porcelain and metal they are accepted worldwide and well known for the treatment they cater. They are trusted not only by the patients but also by the doctors all over the globe.
