All About PFM Crowns: Benefits, Preparation Dimensions, and Everything You Need to Know
Dental crowns are an effective way to restore damaged or decayed teeth. However, with a variety of crown materials to choose from, selecting the right one can be a daunting task. In this blog post, we’ll focus on one of the most popular options, PFM crowns. We’ll discuss the benefits of PFM crowns, the preparation dimensions, and some important things you need to know about them.
PFM stands for porcelain-fused-to-metal, and these crowns are made up of two parts — a metal layer and a porcelain layer. This combination gives PFM crowns the strength and durability of metal, along with the natural appearance of porcelain. PFM crowns are a great option for posterior teeth, and are commonly used for patients who grind their teeth or have a strong bite force.

One of the advantages of PFM crowns is that they can be customized to match the surrounding teeth for a natural appearance. Unlike all-metal crowns, PFM crowns can be color-matched to blend in seamlessly with the rest of your natural teeth. Moreover, PFM crowns are more affordable than all-ceramic crowns.
Next, let’s talk about PFM crown preparation dimensions. The dimensions for PFM crown preparation depend on the amount of tooth structure that needs to be removed, and the amount and type of material that will be used for the restoration. Most PFM crowns require less tooth preparation than traditional full-coverage crowns, as the metal substructure is more durable and requires less thickness for strength. During the preparation stage, your dentist will remove decayed or damaged areas of the tooth, and shape the remaining structure to accommodate the crown.
It’s important to note that not everyone is a candidate for PFM crowns. Patients who have metal allergies may want to avoid PFM crowns due to the metal content. The porcelain layer can also wear down over time, which may require replacement after a certain period. Patients who have grinding or clenching habits may be more prone to chipping or cracking of the porcelain layer.
Another consideration is the PFM crown’s margin. The margin is the area where the crown meets the remaining tooth structure. Ideally, this area should be smooth and tight-fitting to prevent bacteria and food debris from getting trapped and causing decay. Proper margin placement is crucial for the longevity and success of the crown.
In summary, PFM crowns are a popular option for restoring damaged teeth due to their strength, natural appearance, and affordability. They are commonly used for posterior teeth due to their durability and resistance to wear. The preparation dimensions for PFM crowns depend on various factors such as the amount and type of material used and the amount of tooth structure that needs to be removed. While there are certain considerations that patients should take into account, PFM crowns are a great option for many people.
