Magnetic resonance examination is a kind of medical examination method, which is more commonly used in the clinic. The examination itself is not harmful to the human body, but for those who have metal objects in their bodies, they should avoid the examination.

If the dentures are made of non-precious metals, the MRI can be performed even if they are not removed and will not affect the results. Non-precious metal materials can have a heat-making effect during an MRI, causing the metal substance to become hot, which can burn the skin. At the same time, there is a strong magnetic field in the room during the MRI examination, and dentures made of metal in the mouth will be adsorbed into the magnetic field at a very fast speed, thus causing greater harm to the human body. It is recommended that patients first clarify the material of dentures, and then choose the appropriate examination program according to their personal situation to avoid affecting their health.
