Many patients believe that metal or PFM (Porcelain-Fused-to-Metal) crowns must be removed before MRI. This is a common misconception.
The answer in most cases is a BIG NO. :contentReference[oaicite:0]{index=0}
Common Materials Used in Dental Crowns
- Nickel–Chromium (Ni-Cr)
- Cobalt–Chromium (Co-Cr)
These are widely used in India due to strength and affordability.
Are These Crowns Safe in MRI?
- They are non-ferromagnetic or weakly magnetic
- They are firmly cemented to teeth
- They do NOT move during MRI
Conclusion: They are SAFE.
What Actually Happens During MRI?
The main issue is image artifact, not safety.
- Distortion in scan images
- Shadow near crown area
- Mostly relevant in head/face scans
When Removal May Be Considered
- If MRI is for brain, jaw, or TMJ
- If artifact affects diagnosis
- If advised by radiologist
Otherwise, removal is not required.
Key Takeaway
Metal dental crowns are generally MRI-safe. Concerns are related to image clarity—not patient safety.
