PFM
There are many advantages of using Porcelain Fused Metals, or PFMs. We are going to list out 5 advantages on this page.
They Offer Affordable Aesthetics
Extremely Durable
They Can Be Made Using Different Metals
Used for Dental Crowns or Dental Bridges
PFM Restorations Have Been Used for Decades
1. They Offer Affordable Aesthetics
Nowadays, many people are looking to improve the look of their smile, without breaking the bank to afford it. PFM crowns and bridges offer the best of both worlds. They are highly aesthetic like all ceramic crowns, but are far more affordable. Because of this, they are highly popular.
2. Extremely Durable
One main benefit of PFM crowns and bridges is their durability. Out of all the aesthetic options for dental crowns, PFM is the strongest and most resistant to chips and cracks. Because of this strength, PFM crowns and bridges are ideal choices for restoring teeth located in the back of the mouth. They can also be recommended for patients who grind or clench their teeth. Their strength also makes them last longer than other types of dental crowns. On average, PFM crowns can last about 10-15 years.
3. They Can Be Made Using Different Metals
PFM restorations can be made using different metals such as base metal alloys (cobalt, nickel, chromium), titanium alloys, and gold alloys. Base metal alloys are a popular choice, but can cause metal allergies in some people. Titanium alloys can be used and are similar to gold alloys, however gold alloys are still considered to be one of the best metals for PFM restorations. They have the most strength and durability. Gold alloys also do not cause metal allergies.
4. Used for Dental Crowns or Dental Bridges
Porcelain fused to metal crowns are often used to restore teeth that are severely damaged or decayed. A PFM crown is a cap that is cemented over a natural tooth in order to protect it from damage or further decay. A porcelain fused to metal bridge is used to restore missing teeth. PFM bridges are composed of two PFM crowns with a fake tooth in the middle.
5. PFM Restorations Have Been Used for Decades
The first PFM crown was invented in the 1960s. Since then, PFM has been used successfully in dentistry for the fabrication of dental crowns and bridges. The fact that PFM restorations have been around for so long show that they are a dependable choice for restoration fabrication. Although all-ceramic crowns can offer aesthetics, they have not been found to be as dependable as PFM crowns.
