A safe method for studying pathologies of internal systems and organs is magnetic resonance imaging. This type of diagnosis is successfully used in all areas of medicine. Can i do an MRI with dental implants? In certain cases, this may be a contraindication to the procedure.
The essence of the method
MRI is a modern and universal way to diagnose disorders of the human body. The essence of tomography is the use of such a physical phenomenon as nuclear magnetic resonance. In the process of research, the hydrogen atoms in the tissues of the human body supply weak radio signals. They are "caught" and ordered by a special apparatus - a tomograph, consisting of a magnet and supporting a constant magnetic field. The computer helps to process and convert the received information into a three-dimensional image.
Magnetic resonance imaging completely eliminates x-ray radiation. Therefore, most patients with certain indications can do MRI. With dental implants, the procedure is prescribed only individually. The magnetic resonance method is completely safe for the human body.
Indications for appointment
The range of diseases in which an MRI can be prescribed to a patient is quite wide. Due to the lack of x-ray radiation, the method is used to study pregnant women and children from a very young age.
Can i do an MRI with dental implants, braces or crowns? This method is an alternative to computed tomography , which has more contraindications.
Most often, the technique is used when it is necessary to diagnose soft tissues and blood vessels. Diagnostics is recommended in the following cases:
- circulatory disorders;
- thrombosis;
- hemorrhage;
- vascular aneurysms;
- heart diseases;
- pathology of the musculoskeletal system;
- inflammatory processes of various origins;
- diseases of the internal organs.
Can i do an MRI with dental implants?
A huge number of people now have dental designs and products for various purposes, but this is not a reason not to undergo medical diagnostics. In dental practice, magnetic resonance imaging allows you to assess the state of visible and hidden for a simple overview of the dentition. If the patient has pins and other metal structures in the oral cavity, is it possible to do an MRI? With dental implants, many people go through this procedure.
Dentists claim that the presence of metal elements is not a contraindication to magnetic resonance therapy. To get the correct result, you must first notify the specialist about the presence of metal elements and the type of material from which they are made.
When is MRI prescribed in dentistry?
Diagnosis is necessary for patients suffering from the following pathological conditions:
- chewing pain;
- crunch when moving the jaws;
- pain in the lower jaw;
- spasm when closing and opening the mouth.
MRI of the brain
In neurology, the technique of magnetic resonance therapy is used to study impaired functionality of the vessels of the brain, spinal cord, and spinal column. Brain MRI with dental implants is indicated for increased intracranial pressure, suspected stroke, and skull injuries. Diagnosis will help determine the cause of frequent headaches, developmental pathologies, the presence of infectious diseases.
A more detailed picture of the disease allows you to get the use of contrast in the diagnostic process. For this, a special substance is administered to the patient, which enters the blood vessels of the brain through the bloodstream. When exposed to a magnetic field, coloring of problem areas in the image occurs.
Implant Materials
The material from which the dental structure is made may be a paramagnet, a ferromagnet or a diamagnet. They behave differently when exposed to a constant magnetic field. Do MRIs with dental implants from ferromagnetic alloys? The procedure is quite realistic, however, the final result can be greatly distorted.
Currently, experts prefer paramagnets - non-magnetic alloys. One of the popular materials is titanium. It has several advantages over other alloys:
- lack of toxic effects;
- high survival rates of titanium implants with tissues;
- high strength and ductility;
- lack of vanadium in the alloy;
- the presence on the surface of an oxide film that protects against environmental influences;
- the material is not an allergen.
Features of the procedure
MRI with dental implants made of alloys of gold, platinum, palladium can show a distorted picture of the disease. To conduct research in this case is not recommended. It should be borne in mind that the procedure will not bring any harm to a patient who has ferromagnetic implants. Although some tend to think that a displacement or heating of the dental product may occur. Implants are small in size and well fixed products, and therefore you should not be afraid of anything at all.
However, the resulting image will be unreliable and will not allow the doctor to make the correct diagnosis. Before the procedure, it is necessary to check with the dentist the type of material of the dental structures. In the future, this information must be reported to a specialist who will conduct magnetic resonance imaging. This will allow you to properly configure the equipment and get a true picture of the patient's condition.
