Is the rush to all-ceramic crowns justified?

Journal of the American Dental Association (1939)·2014

Porcelain-fused-to-metal (PFM) crowns remain a dental restoration staple, but newer materials are emerging. Consider alternatives for high esthetic demands or metal allergies, while acknowledging PFM

Area of Science:

  • Dentistry
  • Dental Materials Science

Background:

  • Porcelain-fused-to-metal (PFM) crowns have dominated tooth-colored restorations for decades.
  • The market is experiencing a slight decline in PFM use due to the influx of all-ceramic and composite alternatives.

Purpose of the Study:

  • To review the established role and characteristics of PFM restorations.
  • To identify clinical situations where alternative materials to PFM may be indicated.
  • To advise on the transition from PFM to newer restorative materials.

Main Methods:

  • Literature review of PFM restoration properties and clinical applications.
  • Analysis of indications for alternative dental materials.
  • Discussion of PFM advantages, disadvantages, and long-term clinical history.

Main Results:

  • PFM restorations offer proven longevity, acceptable esthetics, minimal fracture, and reliable fit for various situations.
  • Indications for non-PFM materials include high esthetic demands, metal allergies, and patient preference for metal-free options.
  • PFM restorations have a well-documented history of success but also known limitations.

Conclusions:

  • PFM crowns remain a reliable option with a strong clinical track record.
  • Emerging all-ceramic and composite materials present viable alternatives for specific patient needs.
  • Clinicians should exercise caution when transitioning from PFM to less established restorative materials.
