Whether or not an implant denture can be MRI’d depends on what the implant crown is made of; porcelain crowns have some effect, while all-ceramic crowns do not. Metal-based materials have an effect on MRI, while other materials do not. The implant consists of a lower part of the implant that is embedded in the alveolar bone and an upper part of the crown that is exposed in the mouth. The implant is usually made of pure titanium and has no effect on MRI. Crowns are made of a variety of materials, including porcelain crowns, which are made of metal and have an effect on magnetic resonance, and all-ceramic crowns, which have no effect on magnetic resonance. Therefore, the ability to have an MRI done on implant dentures depends on the implant crown. Patients who wish to have an MRI are advised to be aware of the dental implant material in their mouth before proceeding. Please also seek medical attention for any discomfort.
