PFM VS BruxZir® Zirconia
Porcelain-fused-to-metal crowns (PFM) VS BruxZir® Zirconia
Porcelain-fused-to-metal crowns (PFM) have been the only method used throughout the years, offering dentists with dependable, and durable restorations. But PFM is becoming a thing of the past. In recent years, more and more dentists turn to the newest alternative, BruxZir® Zirconia restorations. The requested number for PFM has been lower and lower ever since BruxZir® Zirconia came into the picture. Some dentists, like Dr. Natalya Carmichael, have even switched to only working with BruxZir® Zirconia restorations. Durability, strength and improved looks have led professionals to choose BruxZir® Zirconia Crowns over PFM Crowns. Let’s examine the differences between the two. Let’s take a look at the deference between PFM VS BruxZir® Zirconia.
PFM Crowns.
There are some disadvantages associated with porcelain-fused-to-metal crowns. They include:
The “dark line” phenomenon.
The metal that lies underneath the crown’s porcelain surface can sometimes be seen as a dark line right at the crown’s edge. A dentist will usually try to position the edge of a PFM crown just underneath the tooth’s gum line. But, if a person’s gums happen to recede, this dark line can show, thus spoiling the crown’s appearance.
Achieving superior aesthetics can be a challenge.
While the appearance of a PFM crown can be excellent, it’s often difficult to create one that’s 100% natural-looking. For the most part, this difficulty stems from the crown’s metal substructure and how it must be masked by covering it with relatively opaque (less translucent and therefore less natural-looking) porcelain.
Durability.
It’s possible for the porcelain surface of a PFM crown to chip or break off. If porcelain breakage does occur, it’s very difficult to make a lasting repair. The most predictable solution typically involves making a new crown. As a compromise, some minor chipping may just be smoothed over or polished.
PFM crowns may wear opposing teeth.
The porcelain surface of a porcelain-fused-to-metal crown can create (possibly significant) wear on those teeth that it bites on or rubs against. This issue might be especially important for people who brux (clench and grind) their teeth.
BruxZir® Zirconia Crowns
There are many benefits for patients using a BruxZir® Crown. There is a better feel with these crowns than with the traditional PFMs. They give you more of a perfect fit, according to feedback from actual dental patients. This is something that is ideal for people who grind their teeth. Many times, they can’t withstand other restorations and destroy them with their teeth grinding.
The crowns are chip-resistant because they’re made of solid zirconia, not porcelain, which is easier to chip. This makes them the perfect type of replacement crown, especially for areas with limited space. They are also more attractive and hygienic than porcelain crowns. That’s because they’re glazed so that the surface is smooth. This helps to reduce the accumulation of plaque on the crown itself.
Here are some of the great BruxZir® Crown benefits at-a-glance:
– Cemented conventionally
– Hypoallergenic
– CAD/CAM precision
– Conservative preparation
– Great for para-functional dental patients
– Chip-resistant
– Virtually unbreakable
– Much more attractive than full-cast gold restorations
– Much more affordable full-cast gold alternative
– Comes with a 5-year warranty
