- Porcelain Fused To Metal crown
Porcelain-fused-to-metal (PFM) crowns are a type of dental restoration that combines the strength of a metal base with the aesthetic appeal of porcelain. These crowns are widely used to restore damaged or weakened teeth, providing both durability and a natural appearance.
PFM crowns offer several benefits, making them a popular choice for dental restorations:
The procedure for placing PFM crowns involves several steps:
The dentist prepares the tooth by removing a portion of the enamel to create space for the crown. An impression or digital scan is taken to create a custom PFM crown that fits precisely.
While the permanent PFM crown is being crafted in a dental laboratory, a temporary crown is placed on the prepared tooth to protect it and maintain function.
Once the permanent crown is ready, the temporary crown is removed, and the PFM crown is placed and bonded to the tooth. The dentist will adjust the fit and bite alignment to ensure comfort and proper function.
To ensure the longevity and appearance of your PFM crown, follow these care guidelines:
| Consideration | Description |
|---|---|
| Metal Allergy | Some patients may have an allergy to the metals used in the crown, although this is rare. |
| Gum Recession | Over time, gums may recede, potentially exposing the metal edge of the crown and affecting aesthetics. |
| Porcelain Chipping | While durable, the porcelain layer can chip or crack if subjected to excessive force or trauma. |
| Appearance | The metal core may sometimes cause a slight grayish hue at the gum line, especially if gums recede. |
With proper care, PFM crowns can last 10 to 15 years or longer. Their longevity depends on factors like oral hygiene and the level of wear and tear.
Yes, PFM crowns can be used on both front and back teeth. However, for highly visible front teeth, some patients may opt for all-porcelain crowns for better aesthetics.
Yes, if a crown becomes damaged or worn, it can be replaced with a new one by your dentist.
Initially, a PFM crown may feel slightly different, but most patients quickly adjust and find that the crown feels like a natural part of their mouth.
Porcelain-fused-to-metal crowns provide a reliable and aesthetically pleasing solution for restoring damaged teeth. Consulting with your dentist will help determine if this type of crown is the right choice for your dental needs.
