When it comes to dental crowns, two common materials are used for their construction: Porcelain-Fused-to-Metal (PFM) and zirconia. Both provide a long-lasting solution for patients who require a dental crown, but there are plenty of differences between the two that need to be considered. This article will look at the advantages and disadvantages of each type of crown. By understanding them, you can make an informed decision that is best for your smile.
The Case for PFM
PFM crowns are made by fusing porcelain with metal, creating a strong and durable crown. The metal base ensures durability and strength, making them ideal for restoring heavily damaged teeth. Meanwhile, the porcelain layer gives them a realistic, natural-looking appearance that blends in with the rest of the teeth. PFM crowns are also often more affordable than other types of dental crowns. The metal base also allows them to be used on teeth of any shape or size, making them an excellent choice for different dental restoration needs.
While these crowns are strong, durable, and aesthetically pleasing, they have some drawbacks. For one, PFM crowns can be more expensive than some other types of crowns. Additionally, the metal component of PFM crowns can sometimes be visible along the gum line, which can detract from the aesthetics of the crown. Apart from that, PFM crowns tend to be less biocompatible, meaning they may cause irritation or inflammation of the gums.
The Case for Zirconia
Zirconia dental crowns are made from a strong, durable ceramic material that is highly wear-resistant, making them ideal for restoring teeth that suffer from heavy wear and tear. This kind of dental crown also has a natural-looking, translucent appearance that closely mimics the look of real teeth. Additionally, zirconia dental crowns provide excellent insulation from temperature changes, reducing the sensitivity of the treated tooth. Finally, zirconia is biocompatible and will not cause allergic reactions or discomfort.
In terms of disadvantages, zirconia crowns require more precise measurements from the dentist; there is a higher risk of chipping and breakage. Also, because they are made of a more rigid material, they can be more uncomfortable for the patient than porcelain-fused-to-metal crowns. Lastly, due to their strength, they can be more difficult to adjust if needed.
Which Is Better?
The choice of dental crown is based on personal preference and requirements. PFM crowns can be more cost-effective and provide a lifelike aesthetic, while zirconia crowns tend to be more resilient and less likely to stain or fade. However, what is certain is that both materials offer the required strength and reliability for enhancing the appearance of your teeth. Ultimately, it is a decision that must be made between you and your dentist, considering your needs and desires.
