Which Dental Crown is Right for You? Take Our Easy Self-Test to Find Out!

Choosing between PFM (Porcelain Fused to Metal) crowns, DMLS (Direct Metal Laser Sintering) crowns, and zirconia crowns depends on various factors including aesthetics, strength, durability, cost, and specific clinical needs. Here is a detailed comparison to help you make an informed decision:

PFM Crowns (Porcelain Fused to Metal)

It’s an age-old technique of making ceramic crowns. Handmade with wax patterns and metal casting.


  • Aesthetics: Good aesthetic result as the porcelain can be matched to the natural color of the teeth.
  • Strength: Strong due to the metal substructure, making them suitable for both anterior and posterior teeth.
  • Cost: Generally less expensive compared to zirconia and DMLS crowns.


  • Aesthetics Over Time: The metal underneath can sometimes show through as a dark line at the gum line, especially if gum recession occurs.
  • Wear on Opposing Teeth: Porcelain can be abrasive to opposing teeth, potentially causing wear.
  • Biocompatibility: Some patients may have allergic reactions to the metals used.

DMLS Crowns (Direct Metal Laser Sintering)


  • Precision: DMLS technology allows for highly precise and well-fitting crowns.
  • Strength and Durability: Metal crowns made using DMLS are very strong and durable.
  • Biocompatibility: Generally made from biocompatible metals, reducing the risk of allergic reactions.

  • Aesthetics: Metal crowns are not as aesthetically pleasing as PFM or zirconia crowns because they cannot be color-matched to natural teeth.
  • Cost: More expensive than PFM crowns due to the advanced technology used in their fabrication.

Zirconia Crowns


  • Aesthetics: Excellent aesthetic qualities; can be made to look very similar to natural teeth.
  • Strength: Very strong and durable, suitable for both anterior and posterior applications.
  • Biocompatibility: Highly biocompatible, with very low risk of allergic reactions.
  • Minimal Wear: Causes less wear on opposing teeth compared to porcelain.


  • Cost: Generally the most expensive option among the three.
  • Potential Brittleness: Although strong, zirconia can be more brittle and may chip under certain conditions.

Decision Factors


  • For highly visible areas where appearance is crucial, zirconia or PFM crowns are preferable.
  • If the metal showing through the gum line is a concern, zirconia is the best choice.

Strength and Durability:

  • For areas subject to high bite forces (like molars), zirconia and DMLS crowns are ideal due to their strength.
  • PFM crowns also offer good strength, but less so compared to zirconia.


  • If budget is a primary concern, PFM crowns are the most economical option.
  • DMLS crowns provide a balance between cost and advanced technology.
  • Zirconia crowns, while more expensive, offer superior aesthetics and strength.


  • For patients with metal allergies or sensitivities, zirconia crowns are the best option due to their high biocompatibility.
  • DMLS crowns typically use biocompatible metals, but individual sensitivities should be considered.

Clinical Situation:

  • For patients with heavy grinding or bruxism, zirconia crowns are recommended due to their durability and minimal wear on opposing teeth.
  • For restoring dental implants or in situations requiring precise fittings, DMLS crowns might be preferable.

Crown Selection Self-Test

1. How important is the natural appearance of your crown?

2. Are you concerned about a metal line appearing at the gum line over time?

3. Which teeth need the crown?

4. Do you have a history of grinding or clenching your teeth (bruxism)?

5. What is your budget for dental crowns?

6. Do you have known allergies to metals or dental materials?

7. Are you looking for a long-term solution that requires minimal maintenance?

8. How important is it for you that the crown causes minimal wear on opposing teeth?


Selecting between PFM, DMLS, and zirconia crowns should be based on a combination of aesthetic requirements, functional needs, cost considerations, and individual patient factors. Consulting with a dental professional who can assess your specific situation and provide personalized recommendations is crucial.
