Are there any effects or limitations of having porcelain teeth or dental implants for MRI?

The scientific description is that sometimes, the metal iron ions left in the body may affect the image quality and even the correct diagnosis, because the metal iron ions may affect the uniformity of the magnetic field during the examination, causing the interference of the image and the formation of artifacts, which is not conducive to the display of the lesion. It is safe to perform an MRI, and metals such as gold, silver, and titanium do not interfere meaningfully with the MRI image. Head and neck MRI examinations are safe with a nickel-chromium restoration; The effect of porcelain teeth in the oral cavity on magnetic resonance can be eliminated by adjusting the scanning tomography of magnetic resonance and will not move in the magnetic field, so patients with titanium internal fixations in the body are safe when undergoing MRI examinations, and metals such as gold, silver, and titanium will not have meaningful interference with the MRI images.

Good materials are fine, a friend of mine went down to the mine collapse and opened the scoop on his head and forgot what a good thing, titanium or what, X-ray will go directly to the past without saying that it is okay without magnetism.

Nowadays, there are many edentulous patients, why don't they dare to see a dental clinic for dentists? Because dental implants and dentures hurt them too much, there are a few patients who will go to the dental hospital to see their teeth, they would rather have no teeth than go to your dental hospital, and now there are many rich people, don't they also prefer missing teeth to go for dental implants and dentures? I really hope that your dental hospital can promote the clinical practice of stem cell tooth regeneration, which is the hope that every edentulous patient sees, thank you.

With the development of science and technology, people's pursuit of beauty has been satisfied, not only to meet the beauty of people's face, but also to whiten teeth, porcelain teeth are more and more favored by people. But everything has two sides, and metal is used in porcelain teeth, so does it have an impact on porcelain teeth to do MRI? Let's find out together.

Does MRI of porcelain teeth have an effect

If the porcelain tooth is installed, the MRI examination can still be done, but because the inside of the porcelain tooth is made of metal material, it will produce artifacts on the image of the adjacent parts when the head MRI is done, and if the position of the artifact is exactly the location where the patient needs to observe the lesion, it will indeed have a certain impact. To put it simply, it is equipped with porcelain teeth, and the MRI examination can be done, and it has no effect on the examination of other parts of the body, but the image of the head will have some unclear points.

Other hazards of porcelain tung teeth

After surgery, there may be different degrees of swelling, bleeding and other conditions. Metal allergies may also occur in the later stage, teeth are sensitive after wearing, and gums become sensible. If the porcelain tooth is broken, seek medical attention in time and need to redo the porcelain tooth.

Keep your mouth clean and have regular oral check-ups to prevent dental caries and gum recession. Avoid biting hard things with porcelain teeth. The biggest harm of porcelain tooth restoration of missing teeth is that the damage to adjacent teeth is serious, and the original teeth are much smaller, and they are permanently reduced.

Although porcelain teeth can make teeth look more beautiful, there will also be some drawbacks, so you should not blindly follow the crowd, and choose whether to perform porcelain tooth surgery correctly according to your actual conditions. Once porcelain tooth surgery has been performed, it is necessary to take good care of and clean it to avoid more serious consequences caused by bad conditions.

Dental implants are the crystallization of modern technology, and dental implant technology has made people's dreams of natural and realistic dentures come true. Dental implants are what we often call dental implants, and many people have heard that when doing an MRI examination, there can be no metal objects on the body, otherwise it will affect the results of the examination and even endanger people's safety. If you have removable dentures in your mouth, can you still remove them, can you do MRI for dental implants?

At present, dental implants are basically made of pure titanium or titanium alloy from the implant and abutment, and the upper porcelain is made of *** as the bottom crown, or all-porcelain is metal-free. Therefore, patients who have had implants can have an MRI. It may only have a slight effect on the image of the area around the implant (less than 3 mm radius) and will not affect the imaging of the head and nervous system.

According to Zhide dental experts, the porcelain metals commonly used in oral restoration include gold alloy, nickel-chromium alloy, cobalt-chromium alloy, etc. A large number of experimental data show that gold alloys only have slight artifact interference in magnetic resonance examination, while non-nickel-chromium alloys and cobalt-chromium alloys will produce large artifacts, which have a certain impact on magnetic resonance examinations. In fact, it only interferes with the imaging within a certain range around the restoration.

If the area to be examined is not in the vicinity of the metal restoration, it will not affect the diagnosis of the disease and there is no need to remove the restoration.

Pure titanium dental implants have no effect on MRI.

According to the doctor, the material used for the artificial implant is pure titanium, which is the best biocompatible metal known at present, and it is a non-magnetic metal, and it will not be magnetized in a large magnetic field, so the implant itself has no effect on the magnetic resonance examination. The dentures on the implant may have an impact on the MRI examination, and there are two types of implant denture restoration materials commonly used: all-ceramic and metal porcelain. The all-ceramic material is non-metallic and has no effect on the MRI examination, while the metal porcelain tooth has different degrees of interference with the MRI imaging due to the different metal types.

Is it true that there are non-*** fixed prostheses in the mouth that must be removed first when doing an MRI examination? Not necessarily. This is because these dental alloys do not cause harm to the body during MRI, but only interfere with imaging within a certain range around the restoration.

If the area to be examined is not in the vicinity of the metal restoration, it will not affect the diagnosis of the disease and there is no need to remove the restoration.

Implant experts suggest that people should properly choose the material for denture restoration according to their own situation: the general preferred material is all-porcelain and ***, because this kind of material is not only beautiful but also almost does not bring allergies and other adverse reactions to the human body, and will not interfere with the diagnosis when doing magnetic resonance examination. Of course, if you choose ordinary metal, it is not necessary to remove all of them before the MRI examination, and the doctor will make a judgment based on the actual situation.

Therefore, don't worry too much about those who need dental implants, dental implants are a very safe, comfortable, beautiful and practical dental restoration technology, and it is the greatest achievement in the field of dentistry in the 20th century.

3. If you already know the location of the metal porcelain teeth, you can generally exclude the virtual shadow of the imaging position of ** and the computer. If the material of the porcelain tooth is low in metal, the impression should have little impact.

Generally, there is no effect on the image and does not affect the accuracy of the MRI.

Half ***, i.e. *** 25wt.

Base metals, i.e. ***<25wt. Commonly used dental base metals include nickel-chromium alloys, cobalt-chrome alloys, copper alloys, titanium alloys, and amalgam, among others.

The study showed that the artifacts formed by non-*** fixed restorations could cause distortion of adjacent tissues, and the artifacts had a certain impact on the imaging observation of the eyeball, maxillary sinus and oral structure, but had no effect on the imaging observation of the cranial brain and cervical spine.

It has also been shown that copper alloys, cobalt-chromium alloys and nickel-chromium alloys have different degrees of influence on magnetic resonance, among which nickel-chromium alloy has the most serious interference, which can distort the magnetic resonance imaging of adjacent tissues and have a greater impact on magnetic resonance functional images.

Titanium and amalgam generally have no significant interference with imaging, and studies have shown that pure titanium and amalgam have no effect on magnetic resonance imaging.

Hello is influential, if you do all-ceramic teeth then it doesn't matter!!
