As people who have dental implants are increasing, we are often asked if they can have an MRI (Magnetic resonance imaging).
The question arises because dental implants are metallic objects. An MRI uses a powerful magnet to scan the human body. The magnet can be a problem with things containing ferrous metals (i.e. iron and steel).
However dental implants are made of titanium or titanium alloy, which in any case can not be magnetized since they contain no iron. The same applies to all the alloys used in the oral cavity.
There is no reason to worry about MRIs when you have dental implants. It is safe.
One interesting parameter is that as metal objects, dental implants can distort the MRI image around the area where they are located. This is of value only if the area concerned is near the dental implants.
If you have an over denture supported on implants or any mobile prosthesis with metal reinforcement that can be removed from the mouth, it is advisable to remove it so as to reduce its influence on the magnetic image.
