What are some ways to greatly increase the retention and stability of removable dentures? A magnetic denture can help! A magnetic denture is a type of removable denture that consists of an armature mounted on the remaining tooth roots in the patient’s mouth and a magnet mounted on the denture base, using the magnetic attraction between the two to stabilize the denture and prevent loosening and loss of the denture. Compared with traditional removable dentures, the magnetic denture exerts the least lateral force on the roots of the teeth, which protects the roots of the teeth. More importantly, the magnetic denture can be used effectively to turn loose teeth and root remnants into treasure. The key to a magnetic denture is to have the right roots. Most of the teeth in the mouth are missing and there are a few strong roots left, which is the best indication for a magnetic denture. Partial tooth loss, the remaining roots can also be replaced by metal rings, which is more beautiful. For a full mouth with only a few weak, loose teeth, it is recommended to cut the crown (i.e. saw off the tooth leaving the root) to make a magnetic denture, which will protect the root for a longer period of time and provide retention for the denture. Because of the use of magnets for retention, the magnets will separate from the armature and the denture will automatically dislocate when subjected to harmful forces, which will gently protect the roots. For patients with a loose removable denture and no remaining teeth or roots, there is the option of placing an implant in the jawbone as an artificial root (dental implant) and then having a magnetic denture, but this requires more cost and treatment time. Whether a patient can have a magnetic denture or not should be examined by a professional physician, including taking dental x-rays, and properly designed and operated by a physician skilled in this technology in order to achieve the desired results. Otherwise, improper selection of indications or poor fabrication may accelerate the loosening and loss of the tooth root. Many patients worry about doing magnetic denture is not good for health, Ye Jiantao said, magnetic denture magnet and armature using closed circuit magnetic field design, magnetic force without leakage, after strict testing in the development process, the human body will not produce any harm. Its only drawback is the impact on magnetic resonance (MR) imaging, making the local MR image unclear. Therefore, the denture with the magnet should be removed when doing cranial MR examination.
