Exploring Porcelain Fused to Metal Crowns

Dental professionals constantly seek reliable, efficient, and aesthetic solutions for restorative cases. Among the many options available, durable dental crown options stand out for their balance of strength and appearance. One such option is the porcelain fused to metal crown, a tried-and-tested choice that continues to serve clinicians and patients well. In this post, I will explore the key features, benefits, and practical considerations of these crowns, helping you make informed decisions for your practice.


Understanding Durable Dental Crown Options


When selecting a crown, durability and aesthetics are paramount. Crowns must withstand biting forces, resist wear, and blend naturally with surrounding teeth. Durable dental crown options include all-ceramic crowns, zirconia crowns, and porcelain fused to metal crowns. Each has unique advantages and limitations.


  • All-ceramic crowns offer excellent aesthetics but may lack the strength needed for posterior teeth.

  • Zirconia crowns provide superior strength but sometimes compromise translucency.

  • Porcelain fused to metal crowns combine a metal substructure for strength with a porcelain overlay for natural appearance.


This hybrid design makes porcelain fused to metal crowns a versatile choice, especially for cases requiring both durability and aesthetics.

Advantages of Porcelain Fused to Metal Crowns


Porcelain fused to metal crowns deliver several benefits that make them a preferred option in many clinical scenarios:


  1. Strength and Longevity

    The metal core provides a robust foundation, making these crowns highly resistant to fracture and wear. This strength is particularly valuable for molars and bridges where chewing forces are greatest.


  2. Aesthetic Appeal

    The porcelain overlay mimics the natural tooth’s colour and translucency. While not as lifelike as all-ceramic crowns, they still offer a pleasing appearance suitable for most patients.


  3. Cost-Effectiveness

    Compared to some all-ceramic or zirconia options, porcelain fused to metal crowns often come at a lower cost, making them accessible without compromising quality.


  4. Versatility

    These crowns can be used in various clinical situations, including single crowns, bridges, and implant restorations.


  5. Proven Track Record

    Decades of clinical use have demonstrated their reliability and patient satisfaction.


To maximise outcomes, ensure precise lab communication and accurate impressions. Partnering with a dental lab like Inno Dental Lab can streamline this process, providing advanced digital solutions for implant and prosthetic cases.

What is Another Name for a Porcelain Fused to Metal Crown?


In dental terminology, porcelain fused to metal crowns are sometimes referred to as PFM crowns. This abbreviation is widely used among clinicians and technicians. The term highlights the two main components:


  • Porcelain: The ceramic material that covers the crown, providing a tooth-like appearance.

  • Metal: The underlying substructure that offers strength and support.


Understanding this terminology helps in clear communication with labs and colleagues. It also aids in patient education, allowing you to explain treatment options succinctly.


Practical Considerations for Clinical Use


When planning to use porcelain fused to metal crowns, consider the following clinical factors:


  • Tooth Preparation

Adequate reduction of the tooth structure is necessary to accommodate both the metal substructure and porcelain layer. This ensures proper thickness for strength and aesthetics.


  • Shade Matching

Work closely with your dental technician to select the correct porcelain shade. Although PFMs are less translucent than all-ceramics, skilled layering can achieve a natural look.


  • Margin Design

Metal margins can sometimes show as a dark line near the gumline, especially if gums recede. To avoid this, use a shoulder or chamfer margin design and discuss margin placement with your lab.


  • Occlusion

Check occlusion carefully to prevent porcelain chipping. Adjustments may be needed to reduce excessive forces on the crown.


  • Patient Factors

Consider patient habits such as bruxism, which may influence crown choice. PFMs generally tolerate these stresses well but may require night guards for protection.


By addressing these points, you can enhance the success rate and longevity of porcelain fused to metal crowns in your practice.
