MRI with Dental Implant: All Things You Need to Know

Magnetic resonance imaging (or MRI) is a very common imaging tool to assist doctors in diagnosing health problems that impact the body's tissues and organs.

A variety of soft tissues and organs can be examined with an MRI, including the jaws and teeth. Computer applications are used to convert this data into a 3D picture.

Indeed, MRIs are frequently used to check for malignancies, assess the condition of your heart's chambers, and detect any damage to your brain following a stroke.

During the procedure, a powerful magnetic field is sent through your body's various tissues, and each tissue responds differently to this.

However, going through this procedure is a matter of controversy among those with dental implants.

Dental Implants and MRI

Certain metals, such as cobalt, nickel, and steel, are extremely vulnerable to the powerful force of magnets. They interact with it in certain ways.

Experts refer to these metals as “ferromagnetic metals”, which interfere with MRI accuracy by reacting to the magnetic field generated by the MRI machine.

Therefore, before having an MRI, patients are recommended to take off anything that contains metal.

The majority of high-quality, contemporary dental implants are composed of zirconia or titanium.

Thus, patients who have titanium dental implants can get an MRI without worrying about any safety hazards, side effects, or decreased precision.

Although zirconia and titanium dental implants don't interfere with MRIs directly, MRI may be a true concern for those with previous dental procedures.

You should give a thorough medical and dental history to both your doctor and the treating diagnostic professional when combining dental implants and MRIs.

Ferromagnetic materials found in braces, crowns with metal elements, metal fillings, and even dentures or veneers may cause interference with an MRI scan.

Dental Implant MRI Safety

Since zirconia, titanium, and titanium alloy, which make up the majority of dental implants, are not ferromagnetic metals, it is completely safe to have them in your mouth during an MRI.

However, if you require an MRI, it is always better to let your doctor know that you have dental implants.

Even if you have a very low risk of getting problems during the procedure, metal items in your body can still cause imaging problems.

Any metal crowns, braces, implant-supported dentures, or fillings should also be evaluated or taken away before the procedure.

It is wonderful news for those who can benefit from both dental implants and MRI technologies as they continue to progress.

You don't have to be concerned that dental work will restrict your possibilities for medical imaging in the future because the majority of implants are MRI-safe.

MRI Compatibility Dental Implants

Thankfully, the materials used in the design of the new and updated dental implants reduce the hazards of MRI with Dental Implants.

Indeed, they are designed to be compatible with MRI radiations, at least in most cases.

The main component of dental implant posts, titanium, is non-magnetic and usually safe for MRI scans.

For other components, manufacturers are equally careful to select non-ferromagnetic materials whenever feasible.

Indeed, surgeons can use MRI technology during the dental implant surgery. According to a study, using magnetic resonance imaging (MRI) during computer-assisted implant surgery is a practical and precise process that eliminates ionizing radiation exposure.

MRI Procedure Dental Implants

Although zirconia and titanium dental implants don't interfere directly with MRIs, the procedure should be a bit worrying for those who underwent previous dental procedures.

One of the main benefits of an MRI scan is that it offers superior imaging that can differentiate between fats, water, muscle, and other soft tissues.

Additionally, it is non-invasive, which means that the body is not exposed to radiation because it does not need to be inserted.

Both your doctor and radiologist should go through the patient's medical and dental history.

If it would be useful, you might ask a dentist in your area for information on your dental care before going through an MRI.

There are several additional imaging methods for dental implants besides MRI scans. However, you may ask: How long does a dental implant procedure take? The procedure usually takes between 1-2 hours for each implant.

Dental Implants and MRI Risks

Both people and physicians frequently have worries when patients undergo an MRI while wearing dental implants.

Experts should address these issues to guarantee patient safety and trust going forward.
Since the MRI is incompatible with metallic objects, there have been some questions over its compatibility with dental implants.

However, this is not the case with dental implants, which typically employ non-ferromagnetic titanium and zirconia metals.

They are therefore very compatible with the MRI as they lack iron characteristics and are immune to the powerful magnetic field of the scan. Besides, MRIs are unlikely to lead to implant failure symptoms.

MRI Scan Dental Implant Considerations

Comprehensive guidelines and recommendations of radiology societies are available to guarantee the safe and efficient use of MRI technology in patients who have dental implants.

These recommendations reflect best practices and procedures for minimizing possible hazards and improving imaging outlines, making them a useful tool for patients and healthcare professionals.

The majority of dental implants are composed of non-magnetic materials and are deemed safe for MRI scans, under the American College of Radiology's (ACR) recommendations.

However, with certain implant-supported prostheses or devices with magnetic components, safety measures are highly required.

Dental Implant Types MRI

The magnetic fields produced by MRI equipment vary in intensity. While lower-field machines provide fewer dangers, higher-field machines could interact more with dental implants.

Because titanium, titanium alloy, and zirconia are non-ferromagnetic, getting an MRI while wearing dental implants is safe.

These polymers, which are frequently used in dental implants, enable people to undergo MRIs and other medical procedures without endangering their oral health.

During an MRI, some dental implants or supporting component types composed of ferromagnetic metals may provide hazards or difficulties.

These substances may cause problems when they interact with the powerful magnetic field created during the scan. However, MRI is unliley to cause hurt after a dental implant.

Due to their well-known magnetic characteristics, dental implants composed of particular stainless-steel alloys with a high concentration of ferromagnetic elements may not be suitable for MRI treatments.
The safety of an MRI treatment is further compromised by implants composed of cobalt-chromium alloys, which have magnetic characteristics.

Another possible concern during an MRI is magnetic attachments between dental implants and dentures, which might interfere with the magnetic field of the scanner and result in issues or inaccurate readings.

MRI Guidelines for Dental Implants

Most radiologists receive extensive training on how to reduce and correct picture abnormalities during MRI due to metals or implants.

Despite having dental implants, they use several techniques to get the finest picture quality. Among these tactics are:

• Scan Configuration: To reduce artifacts and enhance picture quality, your radiologist may adjust the MRI machine's parameters, such as the flip angle, echo duration, or slice thickness.
• MRI Coil: To reduce the effect of the dental implant on the picture, your radiologist may switch out the coil type or rearrange the coils.

Frequently Asked Questions

Can I Get an MRI With Dental Implants?

MRI and dental implants may be done safely together. However, metal implants and lead to potential effects, at least in certain cases.

Why Titanium and Zirconia Implants Are Safe for MRI?

Since titanium and zirconia implants are non-magnetic, they don't react with the pulses or magnetic fields during MRI scans. Patients who have these kinds of implants can thus have MRI without issues.

‪Do Dental Fillings Affect MRIs?

The copper, silver, and mercury used in fillings are often unaffected by MRI magnets. Certain elements like cobalt, nickel, and iron are a source of potential problems, however.

Are Dental Crowns and MRIs a Dangerous Combination?

Because dental crowns don't interfere with the magnetic field, they are usually safe during MRI scans.

What Metal Is Not Allowed In MRI?

Items composed of ferromagnetic materials, such as iron, cobalt, manganese, nickel, and some rare earth metals and their alloys, have the capacity to move or twist in a static magnetic field, which might be dangerous.
