What is Glass PFM?

PFM stands for Porcelain Fused to Metal.
Glass PFM refers to dental crowns or bridges where a metal base is covered with glass-like porcelain (ceramic) to look like a real tooth. It combines strength (metal) with natural appearance (porcelain/glass).

This product is mainly used in dental prosthetics (like artificial teeth), especially for patients needing tooth replacement.

?? How is Glass PFM Made?

  1. Metal Framework Creation:

    • A strong metal structure is first created using nickel-chromium, cobalt-chromium, or other biocompatible alloys.

  2. Porcelain/Glass Layering:

    • Over the metal frame, layers of glass-ceramic/porcelain are fused and baked at high temperatures.

  3. Shaping and Coloring:

    • Porcelain is shaped and colored to match the patients natural teeth.

  4. Final Polishing:

    • The crown/bridge is polished and checked for durability and color matching.

Why Use Glass PFM?

  • To replace damaged or missing teeth

  • To improve the appearance of teeth

  • To restore chewing function

  • To protect a weakened tooth after root canal
