Types of Dental Crowns Explained (PFM, DMLS, Zirconia)
Let’s compare the three most commonly recommended crown materials in modern dentistry.
1) PFM Crown (Porcelain-Fused-to-Metal)
A PFM crown has:
- A metal core inside
- A porcelain layer outside for a tooth-like appearance
Best for:
- Back teeth (molars)
- Budget-friendly crown option
- Patients needing moderate durability
Advantages of PFM crowns
- Stronger than normal ceramic crowns
- Affordable compared to Zirconia crowns
- Good for moderate chewing force
Disadvantages of PFM crowns
- May show a dark metal line near the gums over time
- Can cause mild gum irritation in some patients
- Porcelain can chip if the bite is heavy
- Not the most natural-looking crown
Best patient profile:
If you want a balanced crown option with strength + reasonable cost, PFM can work well.

2) DMLS Crown (Metal Crown Made With LASER Technology)
DMLS stands for Direct Metal LASER Sintering.
It is a high-precision metal crown created using advanced LASER 3D printing technology.
Unlike traditional casting, DMLS gives:
- Better fit
- Higher accuracy
- Strong long-term performance
Best for:
- Heavy chewing force/grinders
- Long bridges
- Back teeth
- Patients needing extra strength
Advantages of DMLS crowns
- Extremely strong and durable
- Perfect fit due to digital precision
- Best for patients with bruxism (teeth grinding)
- Less chance of crown fracture
Disadvantages of DMLS crowns
- Less aesthetic (metal inside; porcelain layer may still chip)
- Not ideal for front teeth
- Not as natural-looking as Zirconia
Best patient profile:
If strength matters most – especially for molars, grinders, or bridges – DMLS is a strong choice.
3) Zirconia Crown (Best Aesthetic + Strength Crown)
A Zirconia crown is made from zirconium dioxide, a highly durable ceramic material.
Zirconia is popular because it combines:
- tooth-like appearance
- excellent strength
- gum-friendly design
Best for:
- Front teeth
- Back teeth
- Smile correction
- Patients who want premium crowns
Advantages of Zirconia Crowns
- Highly aesthetic and natural-looking
- Strong enough even for back teeth
- No metal line at gum level
- More biocompatible (gum-friendly)
- Long-lasting with proper care
Disadvantages of Zirconia Crowns
- Slightly higher cost than PFM
- Requires good bite alignment for best results
Best patient profile:
If you want the best overall crown (beauty + durability + comfort), Zirconia is usually the top recommendation.
