The impact of dentures during MRI depends on the material of the dentures. If the dentures are made of non-metal, such as porcelain, there is no effect on the MRI exam, and if the dentures are made of precious metals, such as titanium or gold, there is not much effect on the exam. If it is a cheaper metal, such as nickel-chromium alloy or cobalt-chromium alloy, it will have a greater impact on the MRI results, causing the dentures to shift and deform, which can seriously cause the patient to choke and produce artifacts on the image, and if the patient is examined in the head or adjacent areas such as the nasopharynx, the results are affected leading to misdiagnosis. For safety reasons, it is best to remove the dentures in advance before doing the MRI, and if they cannot be removed to know the composition of the dentures, the MRI room doctor will determine the safety before conducting the examination.
