What Is a PFM Dental Crown?

A Porcelain Fused to Metal (PFM) crown is a custom-made dental restoration consisting of two layers:

Inner Metal Framework

The internal metal coping provides exceptional strength and structural support.

Outer Porcelain Layer

A tooth-colored ceramic (porcelain) layer is carefully fused to the metal framework, creating a restoration that closely resembles a natural tooth while maintaining excellent durability.

This combination allows PFM crowns to provide:

• High mechanical strength
• Good aesthetics
• Reliable long-term performance
• Excellent chewing function
• Wide clinical applications

Because of their predictable performance, PFM crowns continue to be recommended in many restorative situations, particularly where both strength and appearance are important.

Why Are PFM Crowns Still Popular?

Many patients believe that newer materials have completely replaced PFM crowns.

In reality, PFM crowns continue to be widely used throughout the world because they have demonstrated decades of successful clinical performance.

Dentists continue to recommend PFM crowns because they offer:

• Strong metal support
• Natural tooth-colored appearance

Modern manufacturing techniques such as DMLS have further improved the precision and quality of PFM restorations.

What Is DMLS Technology?

Direct Metal Laser Sintering (DMLS)

One of the most significant advances in crown and bridge dentistry is the introduction of Direct Metal Laser Sintering (DMLS).

Instead of producing the metal framework through traditional casting, DMLS uses advanced computer-controlled laser technology to manufacture highly accurate metal copings layer by layer.

The process begins with a digital CAD design of the crown framework.

A high-energy laser then selectively fuses extremely fine cobalt-chromium alloy powder according to this digital design, creating a precise three-dimensional metal framework.

The porcelain is subsequently bonded to this framework to complete the PFM crown.

DMLS technology combines:

• Digital precision
• Advanced metallurgy
• CAD/CAM design
• Laser manufacturing
• Excellent framework accuracy

Why We Prefer DMLS Technology for PFM Crowns

At Dr. Bharat Katarmal Dental and Implant Clinic, we believe that the quality of a PFM crown depends not only on the ceramic used—but also on how the metal framework is manufactured.

For this reason, whenever clinically appropriate, we prefer Direct Metal Laser Sintering (DMLS) over conventional casting techniques.

DMLS enables the metal framework to be digitally designed and manufactured with remarkable precision, helping us achieve restorations that fit accurately and perform predictably.
