Dental implants are a popular and effective solution for people who have lost one or more teeth. They are designed to look and feel like natural teeth, providing a long-lasting and durable replacement for lost or severely decayed teeth. However, some patients with dental implant and mri may be concerned about undergoing magnetic resonance imaging (MRI) scans, as there is some concern that the implants may interfere with the imaging process.

This post from Sydney Dental will cover the relationship between dental implants and MRI and provide advice to those undergoing a dental implant that may require an MRI scanning.

1. What are dental implants?

Dental implants are a type of dental prosthesis that are used to replace missing teeth. They are typically made of titanium or other biocompatible materials, and are surgically placed into the jawbone. The implants are designed to integrate with the surrounding bone tissue, providing a stable and secure foundation for replacement teeth, such as dental crowns, bridges, or dentures.

Dental implants have become a popular solution for people who have lost one or more teeth, as they offer several advantages over other tooth replacement options. For example, dental implants:

  • Are long-lasting and durable;
  • Look and feel like natural teeth;
  • Provide a stable and secure foundation for replacement teeth;
  • Help to prevent bone loss and preserve the jawbone structure;
  • Do not require the alteration of adjacent teeth, as with bridges;
  • However, despite their many benefits, some patients with dental implants may be concerned about undergoing MRI scans.

2. What is MRI?

MRI is a medical imaging technique that uses a powerful magnetic field and radio waves to produce detailed images of the body’s internal structures. MRI can be used to diagnose a wide range of medical conditions, including neurological disorders, cancers, and musculoskeletal injuries.

MRI is a safe and non-invasive imaging technique that does not use ionizing radiation. However, because it relies on a strong magnetic field, there are some concerns that certain medical devices, including dental implants, may interfere with the imaging process.

An MRI may be used to assess the quality and quantity of bone in the jaw prior to dental implant placement. This is typically done when a patient has experienced severe trauma to the face, or if they have a medical condition that affects bone density or quality. In such cases, an MRI can provide additional information about the extent of the injury or condition, which can aid in implant placement planning.

It is important to note that an MRI cannot be used during the actual implant placement surgery, as the strong magnetic field of the MRI machine can cause metal implants to move or heat up, which can be dangerous for the patient. Therefore, CBCT is the preferred imaging modality for dental implant placement, and is widely used by dental professionals for this purpose.

3. Can dental implants interfere with MRI results?

The potential for dental implants to interfere with MRI depends on several factors, including the type of implant, the strength of the magnetic field, and the location of the implant in the body.

Most dental implants are made of titanium, which is not magnetic and is therefore not affected by the strong magnetic field used in MRI. However, some dental implants may contain small amounts of ferromagnetic materials, such as iron or cobalt, which can be magnetized by the strong magnetic field used in MRI.

If a dental implant contains ferromagnetic materials, it may cause artifacts or distortions in the MRI images, making it difficult for radiologists to interpret the results accurately. In some cases, the implant may also cause local heating, which can be uncomfortable or even dangerous for the patient.

To minimize the risk of interference, it is important for patients to inform their healthcare providers about any dental implants or other medical devices they may have before undergoing an MRI. This will allow the healthcare provider to select the appropriate imaging protocol and take any necessary precautions to ensure patient safety and image quality.

4. What should patients be careful about?

It is advisable that those getting dental implant treatment that requires an MRI should take the following precautions:

4.1. Inform your healthcare provider

Be sure to inform your healthcare provider about any dental implants or other medical devices you may have before undergoing MRI. This will allow the provider to select the appropriate imaging protocol and take any necessary precautions.

4.2. Check your implant materials

If you are considering dental implants, be sure to ask your dentist about the materials used in the implant. Most dental implants are made of titanium, which is not magnetic and will not interfere with MRI. However, if the implant contains ferromagnetic materials, it may cause artifacts or distortions in the MRI images.

4.3. Consider alternative imaging techniques

If you have dental implants that may interfere with MRI, your healthcare provider may recommend alternative imaging techniques, such as computed tomography (CT) or ultrasound. These imaging techniques do not rely on a strong magnetic field and are less likely to be affected by dental implants.

4.4. Follow pre-scan instructions

Before undergoing an MRI, you will be given instructions on how to prepare for the scan. Follow these instructions carefully to ensure that you are adequately prepared and to minimize the risk of complications.

4.5. Inform the MRI technologist

When you arrive for your MRI scan, inform the MRI technologist about any dental implants or other medical devices you may have. The technologist will take extra precautions to ensure that the implant does not interfere with the imaging process and that you are safe throughout the procedure.

5. A note from Sydney Dental

All in all, dental implants serve as an optimal tooth restoration method for millions of patients around the world. Those who are taking dental implants into account or have already undergone dental implants should inform their healthcare providers about the treatment  before getting an MRI. With the proper consideration and imaging protocols, patients with dental implants can safely receive MRI and receive the diagnostic information needed to support the implant treatment and improve their overall well-being.
