Porcelain Fused Metal Crowns, or PFM crowns, are dental restorations that combine the strength and durability of metal with the aesthetics of porcelain.Read on https://bellavisomedicalcenter.ae/dentistry/porcelain-fused-metal-crowns/
They are a dependable and affordable option for restoring damaged, decayed, or missing teeth. They are also more biocompatible than other dental materials, allowing them to last longer and be better tolerated by the gums and bone structure.
Strength
Porcelain Fused Metal Crowns (PFM) are bi-layered restorations that consist of a metal substructure and porcelain on top. They are a dependable, durable option that is recommended by many dentists for restorations that require excellent strength and durability.
A number of different materials are used for PFMs, including feldspathic porcelain. Today, more options are available that utilize advanced ceramics.
Zirconia is the strongest tooth-colored material on the market, and it has a natural translucency that gives it an esthetic appearance. Glidewell offers zirconia crowns in two formulations: BruxZir Full-Strength and BruxZir Esthetic.
Durability
Porcelain Fused Metal Crowns are one of the most durable tooth crown options available. With proper care, they can last for around 15 years.
This type of crown is fabricated with a metal-alloy interior and a porcelain exterior. This combination enables them to have the strength of metal crowns while also offering visual appeal and a natural-looking appearance.
Moreover, these crowns can be designed to fit the shade of surrounding teeth. This makes them a popular choice for patients who need to restore front teeth.
However, PFM crowns are not recommended for patients with metal allergies. They can also cause wear on opposing teeth, which may be uncomfortable for some people. In addition, they can also push back the gum line. This can occur if the metal portion of the crown rubs against the gum tissue.
Aesthetics
Porcelain Fused Metal Crowns, also called PFM crowns, are fabricated by bonding a metal-alloy interior to a porcelain exterior. This two-material composition gives them durability and a tooth-colored esthetic that is preferred by many dentists.Optimal Esthetics
The challenge with PFM crowns is that their internal metal framework must be masked by a very opaque (less translucent and therefore less natural-looking) porcelain layer. This often results in a grey line that shows at the gumline, spoiling the overall appearance of the restoration.
All-ceramic crowns can achieve excellent esthetics, especially when crafted from lithium disilicate (e.max(r)). They can also offer varying degrees of translucency, based on the strength and density of the specific material.
Comfort
Porcelain Fused Metal Crowns (PFM) are a tried-and-true restoration that has been used by dentists and patients for decades. They offer strength and durability and can work well in cases that require precision attachments or when minimal inner occlusal space is available.
They are a great option for bridges that last for many years, and they have been known to help prevent night grinding. But PFM crowns may not be the right choice for you if you suffer from metal allergies or have gum disease.
Regardless of the material, tooth restorations require careful preparation before placement. This ensures that the lab has enough space for a natural-looking restoration and that the porcelain fused to metal crown fits correctly over the tooth.
Convenience
Porcelain Fused Metal Crowns (PFM crowns) combine the strength of a metal base with the aesthetics of porcelain. They can be made in a variety of colors and shades to match the surrounding teeth, making them ideal for patients who want their crowns to blend in with the rest of their smile.Book Your Appointment on BellaViso.
These types of restorations also have a reputation for being less susceptible to cracking than traditional all-ceramic crowns. They can last for decades if they are properly cared for.
Another advantage is that PFM crowns are bio-compatible if the dentist chooses a high noble metal substructure, such as gold. Nonetheless, some patients may be concerned about the metals in PFM crowns. This is because they can irritate the gum tissue, which can lead to a receding gum line.
