With the advancement of science and technology, people are paying more and more attention to oral health. As an advanced method of tooth restoration, titanium dental implants are favored by more and more patients. However, many people worry about whether it will affect the results of MRI examinations when choosing dental implant materials. This article will reveal to you the relationship between titanium dental implants and magnetic resonance.
What are the advantages of titanium for dental implants?
Pure titanium can be used to make crowns, bridges, and brackets for removable dentures. Compared with traditional dental metal materials, it has excellent physical and chemical properties, good biocompatibility, small specific gravity, and corrosion resistance.
Titanium artificial bones, artificial joints, cardiac pacemakers, artificial tooth roots, etc. have been widely used in clinical practice. In addition to excellent tissue affinity, dentures made of pure titanium also have the following advantages:
lightweight
Titanium has a small specific gravity, which is 1/4 of gold alloy and 1/2 of cobalt-chromium alloy. Therefore, dentures made of pure titanium will be much lighter, which can reduce the burden on the remaining tissues in the mouth and have better Comfort.
Moderate hardness
It is between enamel and dentin, so crowns made of pure titanium will not wear too much on the natural teeth in the opposite jaw. Using pure titanium to make posts in the tooth roots can make the stress conduction in the tooth roots more consistent with physiological patterns and reduce the risk of tooth root fractures.
Low thermal conductivity
Crowns made of pure titanium can better isolate hot and cold stimulation, help protect the dental pulp, and will not cause soreness when eating cold or hot food.
No taste interference
Titanium metal has good stability, does not have a metallic taste in the mouth, and does not cause taste interference.
Radiolucent to X-rays
Titanium is semi-transmissive to X-rays. When wearing a crown made of pure titanium, you can check whether there is any caries inside the crown when taking X-rays, to achieve early detection and early treatment. This is used for making dentures. Advantages that other metal materials do not have.
Better magnetic resonance compatibility
Titanium metal is a non-paramagnetic metal. Compared with commonly used cobalt-chromium alloys and nickel-chromium alloys, titanium produces minimal artifacts during magnetic resonance examinations and has little impact on magnetic resonance examinations. In most cases, it is not necessary to remove the pure titanium denture during a head MRI examination.
Do titanium dental implants affect magnetic resonance imaging?
1. Introduction to titanium dental implants
Titanium dental implants are currently one of the most ideal ways to repair teeth. They use titanium metal materials to make artificial tooth roots and then connect the implants to the alveolar bone to achieve the purpose of fixing the teeth. Titanium metal has good biocompatibility, mechanical properties, and corrosion resistance, so it is considered the best material for tooth restoration.
2. Magnetic resonance principles and influencing factors
Magnetic resonance examination (MRI) is a non-invasive examination method that uses strong magnetic fields and radio waves to image the internal structures of the human body. Many factors that affect MRI examination results, including human implants, iron objects, electronic equipment, etc., which may interfere with the examination results.
3. Will titanium dental implants affect magnetic resonance examinations?
Experiments have proven that titanium dental implants will not have a significant impact on magnetic resonance examinations. This is because titanium metal material is not magnetic and cannot be magnetized by an external magnetic field. In addition, titanium implants have good compatibility with surrounding tissues, will not cause inflammatory reactions, and will not release any radioactive substances. Therefore, patients can feel confident using titanium dental implants during MRI examinations.
4. How to avoid potential risks
Although titanium dental implants will not have a significant impact on magnetic resonance examinations, to ensure safety, patients still need to inform the doctor that they have used titanium dental implants before undergoing magnetic resonance examinations. In addition, patients should also pay attention to avoid wearing jewelry, clothing, and other items containing iron parts in daily life to avoid interfering with the test results.
Titanium dental implants are an advanced method of tooth restoration, and the material itself will not affect the results of magnetic resonance examinations. However, to ensure safety, patients still need to pay attention to avoid potential risks when undergoing MRI examinations.
