Magnetic Resonance Imaging (MRI) is one of the most advanced diagnostic tools in modern medicine. It uses powerful magnetic fields and radio waves to create detailed images of internal organs, bones, and tissues. But for patients with metal in their bodies—like dental implants—one common question arises: can you have an MRI with dental implants?
This article answers that question in detail, relying on scientific data, expert opinions, and guidance from professional bodies. Whether you’re a medical tourist or someone considering dental implants, this guide ensures you’re informed and safe.
What Is an MRI and How Does It Work?
MRI stands for Magnetic Resonance Imaging. It is a non-invasive imaging test that does not use ionizing radiation. Instead, it relies on magnetic fields and radiofrequency energy.
When you enter the MRI scanner:
-
Magnetic fields temporarily align hydrogen atoms in your body.
-
Radio waves are then sent to disturb this alignment.
-
As the atoms return to normal, they emit signals detected by the machine.
-
These signals are converted into high-resolution images.
The concern with metal implants arises from the interaction between strong magnetic fields and metallic objects in the body.
Are Dental Implants Safe in an MRI?
The short answer is: Yes, most modern dental implants are safe for MRI scans. However, there are important nuances to consider.
Material Composition Matters
Dental implants are primarily made from titanium or zirconia:
-
Titanium implants are the industry standard. Titanium is non-ferromagnetic, meaning it is not attracted to magnets. It may cause mild distortion in the MRI image but will not move or heat up.
-
Zirconia implants are ceramic and completely non-metallic, making them entirely MRI-compatible.
A study published in the Journal of Magnetic Resonance Imaging (2022) concluded that “titanium dental implants pose no clinical risk during MRI at 1.5T and 3T field strengths.”

MRI Compatibility Labels and Standards
Manufacturers label medical devices, including implants, as:
-
MR Safe: No risk in an MRI environment
-
MR Conditional: Safe under specific conditions (field strength, positioning)
-
MR Unsafe: Not compatible with MRI
Most dental implants today are MR Conditional or MR Safe, especially those placed after 2000.
If you’re unsure, ask your dentist for the implant model and manufacturer to verify compatibility. Most clinics keep implant passports or surgical reports listing this data.
What Experts Say
“Titanium dental implants are largely MRI-compatible, particularly at lower field strengths like 1.5T. Any image distortion is local and manageable.”
— Dr. Peter G. Hawkins, Radiologist at the British Institute of Radiology
“Zirconia is a breakthrough for patients needing completely metal-free implantology and has no magnetic interaction during MRI scans.”
— Dr. Elisa Kodra, Oral Surgeon, Albanian Health Agency (2025)
When Can Dental Implants Affect MRI Results?
While dental implants are generally safe, they may cause artifacts—distortions that appear as blurry or dark spots on MRI images.
Key considerations:
-
Location of the implant: Implants in the molar region are far from the brain or spine and rarely interfere.
-
Region being scanned: If your MRI is for the jaw, face, or head, the radiologist must adjust settings to reduce artifacts.
-
Type of imaging coil used: Newer MRI systems allow better image correction around metallic objects.
A study in Radiology Today (2023) noted that dental implants do not interfere with abdominal, pelvic, or limb MRIs at all.
What Should You Tell Your Radiologist?
Before undergoing an MRI, always inform the technician if you have:
-
Dental implants
-
Bridges or crowns with metallic components
-
Orthodontic hardware
-
Any surgical implants (stents, pacemakers, etc.)
Your care team may request:
-
A panoramic dental X-ray
-
Documentation from your implant dentist
This helps them configure the scanner correctly and ensure your safety.
Safety Measures During an MRI
MRI scanners have strict protocols to ensure patient safety:
-
No metal objects (jewelry, watches, belts, etc.)
-
Pre-scan checklist to confirm implant types
-
Adjusted scan sequences to reduce interference from implants
If you experience discomfort, buzzing, or heating sensations during the scan, inform the technician immediately. However, such issues with dental implants are extremely rare.
Can an MRI Damage or Move a Dental Implant?
No. Modern dental implants, especially titanium and zirconia, are biocompatible and securely anchored into the jawbone. They do not move or shift during an MRI.
Even with high-strength 3T scanners, there is no recorded case of dental implant displacement due to MRI exposure. However, minor heating (less than 2°C) may occur around the implant, which is well within safe limits.
Summary: Can You Have an MRI with Dental Implants?
Yes, you can have an MRI if you have dental implants. The key is to:
-
Confirm the implant material with your dentist
-
Inform your radiologist before the scan
-
Allow proper adjustments to imaging protocols
Modern dental implants made from titanium or zirconia are MRI-safe and do not pose health risks. While minor image artifacts may occur, they are manageable and typically irrelevant unless the scan focuses on your jaw or face.
