Ms. Chang, 63 years old, wearing removable dentures for many years, dentures not only often loose, but also placed metal hooks (snap ring) of the teeth one by one loose off, see the only two left in the lower jaw tiger teeth also wobbly, and then put wire hooks? Will the only two remaining teeth be lost? It will be more uncomfortable to have full dentures after all the teeth are lost, right? Ms. Chang fell into the distress …… In fact, in our country gradually into the aging society, life with Ms. Chang’s troubles of patients are not a few. Dentures loose, unstable, pressure pain, large open mouth dentures will fall down – “laugh off teeth”, and chewing strength is not enough, not beautiful, quality of life significantly reduced. Is there a solution to this problem? In Japan, the magnetic attachment denture has benefited more than 600,000 patients. In China, magnetic attachment denture is still an unfamiliar concept to most people. A magnetic attachment is a device that uses the magnetic force of a magnetic material to attach the denture to the roots of the teeth, allowing the denture to gain retention and stability. It consists of an armature mounted on the root of the remaining teeth in the patient’s mouth and a magnet mounted on the denture base, which uses the magnetic attraction between the two to stabilize the denture and prevent loosening and loss of the denture. This kind of denture with magnetic attachment to provide retention and stability is called magnetic attachment denture. It is known as the third generation denture retainer because of its reliable retention, small size, aesthetics, ease of use, no lateral force transmission, and wide range of applications. Dr. Zhang Cuicui, assistant of Associate Professor Ye Jiantao, said: We have made a lot of magnetic attachment denture in recent years, and patients are very satisfied. The outstanding advantages of magnetic attachment denture and the applicable population: 1, magnetic attachment denture without complex metal ring device, simple construction, easy to take off and wear. Many patients have experienced that removable dentures are sometimes difficult to take off and put on, especially for the elderly, who have slightly less finger dexterity, and because of the design of dentures, it takes several minutes to remove or put on the dentures. The wrong direction of force or the use of brute force can also cause trauma to their teeth. Therefore, for older people, especially those with poor finger dexterity, or with post-stroke sequelae, you can choose magnetic dentures when doing active denture repair, which are easier to put in and take out while ensuring better suction. 2, loose teeth and residual roots and crowns can use the magnetic attachment to the root of the characteristics of the small lateral force, without extraction. The retained roots are covered under the dentures, which can slow down the resorption of alveolar bone, retain the sensitivity and effectiveness of chewing, and also conduct the physiological stimulation to the brain when chewing, which is beneficial to health. It avoids the inconvenience of extracting all the loose teeth and rotten roots of some patients and then making full dentures. Do not pull teeth easily, and magnetic attachments can be used effectively for loose teeth and roots, turning waste into treasure. 3, wear movable dentures patients are often equipped with some fixed role of “metal hooks”, even located in the open mouth visible position, seriously affect the aesthetic, and magnetic attachments can replace the metal ring, so that the dentures more beautiful. For patients with high aesthetic requirements, the magnetic attachment denture is the first choice. In addition, magnetic attachments are simple to construct, so cleaning and maintenance can be done easily. In addition, the magnet and the armature of the magnetic denture are designed with a closed circuit magnetic field, so there is no leakage of magnetic force, which is strictly tested during the development process and does not cause any harm to the human body. In addition, the armature mounted on the root itself does not have magnetic properties, its role is equivalent to that of a nail, only when it touches the magnet will it attract each other. And the magnet installed in the denture base is not worn 24 hours a day, movable dentures are not worn at night. So patients do not have to have the feeling that magnetic things in the mouth will be detrimental to health concerns.
