MRI, or in other words magnetic resonance imaging, is an image that helps to accurately establish a diagnosis, examine the functioning of internal organs, detect tumors and monitor chronic diseases. Its advantage is that it does not use x-ray radiation, which means it is as safe as possible for human health. Is it possible to do an MRI with dental implants? This is a question that plagues dental office patients. There are stories among people that after examination they become dislodged, fall out and even explode. But is this true or is it true?
What's happened?
Magnetic resonance imaging is one of the main methods used to diagnose brain diseases. In its process, detailed images are taken to diagnose the presence of a tumor, aneurysm, head injury, malfunction of blood vessels and the pituitary gland. Based on its results, a treatment method can be prescribed.
How is it carried out?
The procedure involves a special table on which the patient lies. This table automatically slides into the cylindrical shape of a special scanner. When performing a tomography, the patient must wear headphones, as the device makes some noise. The doctor performing the examination uses radio waves to adjust the image quality and the patient should not move for 10-30 minutes so as not to distort the diagnostic results.
During the procedure, two-way audio communication is used between the patient and the doctor. If the patient does not feel well during the process, he can inform the doctor about it. Sometimes, for the accuracy of the study, the subject cannot breathe.
Contraindications for MRI
Metal objects are not allowed to be present in the tomograph scanner. There are also a number of contraindications:
- tattoos made with certain dyes;
- clips for adjusting blood circulation pressure in blood vessels;
- ferromagnetic devices or implants, pacemakers.
MRI and are compatible, however, in order to avoid distortion of the results and any complications, you should prepare in advance.
Features of magnetic resonance therapy of patients with dentures
If a person with removable dentures is shown an MRI image, then there is no problem at all. I took off the prosthesis, went through the procedure and put it back on. In addition, pins, prostheses or implants made of gold or similar neutral materials are safe. Prostheses made of nickel, chromium and steel can cause distortion in the images.
Braces
Metal structures are installed to correct the appearance and bite of teeth. When diagnosing with a tomograph, they have a big drawback - a large impact area, which can lead to serious distortion of the study results.
When prescribing such a procedure, the patient will have to temporarily stop wearing braces, especially if we are talking about identifying an aneurysm or brain tumor.
Pins and implants
Another type of metal structures is crowns or. They are usually mounted on iron or titanium pins. The materials from which these dental structures are made are inert, which means they are not harmful to the body, but are extremely undesirable when performing tomography.
Is it possible to do an MRI with dental implants? This question is not clear-cut. If diagnostics are required for the abdominal cavity and other organs located below the lower back, then the presence of prostheses will not have any effect on the image.
When diagnostics is required for organs located above the lower back, in the neck, pituitary gland, brain and chest, serious distortions in the final tomography result can occur here. But you should understand that any examination has to be done with them, i.e. Removing dental structures and installing them again is not a cheap pleasure.
Metal prostheses
Each patient, when installing implants, should know for himself in the future what raw materials the product is made from. If it contains metal or metal-ceramics, then the doctor who will perform the MRI should be warned about this.
Let's dispel the myth - a prosthesis attached to hard bone tissue does not shift in any way under the influence of radio waves, but the result of the study will be slightly distorted.
If the medical institution has the appropriate equipment, the doctor can adjust the tomograph settings so that the negative impact from the tomograph is minimal. In addition, you can use another diagnostic option, for example, CT.
Rules for preparing for diagnostics
MRI with titanium is possible, but their presence will distort the final result of the study on a magnetic resonance imaging scanner. However, they do not in any way have a negative effect on the body. In addition, they do not become deformed or fall out after the examination.
First, you need to understand which organ will be examined. If it is below the lower back, then there is no need to worry, but if it is higher, then this is a reason to think about it. If you have removable dental structures, for example, braces or dentures, then it is better to remove them, and if the dentures are permanent, then you must warn the doctor about this.
Knowing the specifics of the patient, the specialist will decide to change the equipment settings during the study or refer him to a clinic with more modern and improved equipment. In addition, another type of examination may be offered.
Thus, when the doctor knows in advance about the possible distortion of the results, he will already understand what to do in the current situation and what points to focus on.
