Can you still do head ct and MRI after dental implant?

Dental implant is the crystallization of modern science and technology, which makes people realize the dream of natural and realistic dentures. Dental implants are what we often say. Many people have heard that you can't have any metal objects on your body when doing MRI, otherwise it will affect the inspection results and even endanger people's safety. There are removable dentures in the mouth, which can be removed. Can dental implants do MRI? At present, the implants and abutments of dental implants are basically pure titanium or titanium alloy, and the upper porcelain is made of precious metal as the bottom crown, or all porcelain is metal-free. So patients who have been implanted can have an MRI. It may only have a slight impact on the image of the local area around the implant (radius less than 3mm), and will not affect the imaging of the skull and nervous system. According to dental experts, the commonly used porcelain metals in dental restoration are gold alloy, nickel-chromium alloy and cobalt-chromium alloy. A large number of experimental data show that precious metals such as gold alloy only slightly interfere with the test of magnetic vibration, while non-precious metals such as nickel-chromium alloy and cobalt-chromium alloy will produce large artifacts, which have a certain impact on the test of magnetic vibration. In fact, it only interferes with imaging in a certain range around the prosthesis. If the part we want to check is not near the metal prosthesis, it will not affect the diagnosis of the disease, and it is not necessary to take out the prosthesis. Pure titanium dental implants have no effect on magnetic resonance imaging. According to the doctor, the artificial implant is made of pure titanium, which is the most biocompatible metal, non-magnetic and will not be magnetized under a large magnetic field, so the implant itself has no effect on magnetic resonance examination. It is the denture on the implant that may affect the magnetic resonance examination. At present, there are two kinds of commonly used implant denture restoration materials: all-ceramic and porcelain-fused-to-metal. All-ceramic materials are nonmetals, which have no influence on magnetic resonance imaging, while metal porcelain teeth have different degrees of interference on magnetic resonance imaging due to different kinds of metals. Is there any non-precious metal fixed prosthesis in the mouth that must be taken out first when doing magnetic vibration examination? Actually, not necessarily. Because these dental alloys will not cause harm to the body when doing magnetic vibration examination, but only interfere with imaging in a certain range around the restoration. If the part we want to check is not near the metal prosthesis, it will not affect the diagnosis of the disease, and it is not necessary to take out the prosthesis. Implant experts suggest that people should choose appropriate denture restoration materials according to their own conditions: generally, all-ceramic and precious metal materials are preferred, because these materials are beautiful and will hardly bring adverse reactions such as allergies to the human body, and will not interfere with diagnosis when doing magnetic resonance examination. Of course, if you choose ordinary metal, you don't have to remove it all before magnetic vibration inspection. The doctor will make a judgment according to the actual situation. So friends who need dental implants don't have to worry too much. Dental implant is a very safe, comfortable, beautiful and practical dental restoration technology, and it is the greatest achievement in the dental field in the 20th century.
