Ms. Chang had been wearing removable dentures for many years, and not only were the dentures often loose, but even the teeth on which the metal hooks were placed were wobbly. Will she lose her only two remaining teeth? In life, there are not a few elderly people who have such worries as Ms. Chang. The dentures are loose, unstable, painful to press, and even fall out when you open your mouth, as well as not chewing hard enough, which affects eating. Is there a solution to this problem? Magnetic attachment denture (denture) can help people with this trouble. It consists of an armature mounted on the roots of the remaining teeth in the patient’s mouth and a magnet mounted on the denture base, which utilizes the magnetic attraction between the two to stabilize the denture and prevent it from loosening and falling out. Many patients have experienced that it is sometimes difficult to take off and put on movable dentures. Using force in the wrong direction or brute force can also cause trauma to your teeth. However, magnetic attachment dentures do not have complex metal clasps and are simple in construction, making them easy to remove and wear. Therefore, for the elderly, especially those with poor finger dexterity, or with the sequelae of a stroke, magnetic denture can be chosen when doing removable denture repair. With this new technology, loose teeth and residual roots can also be effectively utilized to avoid the inconvenience of making full dentures. In addition, the magnetic attachment can replace metal clasps, making the denture more beautiful. In addition, magnetic attachment denture construction is simple, cleaning and maintenance can be easily done. The magnet and armature of the magnetic denture are specially designed so that the magnetic force will not leak and will not be harmful to the human body. It is important to note that the patient should be examined and judged by a professional physician to determine whether the patient is suitable for a magnetic denture, and a physician skilled in this technology should carry out the correct design and operation in order to achieve the desired results. Patients who have magnetic denture should take out the movable denture with magnet to avoid affecting its accuracy when doing head and face magnetic resonance examination. These patients also need to pay attention to oral hygiene, especially brushing around the armature on the roots of the teeth in the mouth. Magnetic denture is not suitable for those who have poor root conditions, cannot maintain oral hygiene or patients with malignant tumors of the head and face who need frequent MRI examinations before and after surgery.
