Conventional dentures often have dentures shaking or falling from the gum when the denture is installed on the gum. Implants are intended to address these shortcomings. Implant dentures have the advantage of being firmly fixed compared to conventional dentures However, implant dentures are complex in structure, time consuming to implant, complex to plant, and even after installing implant dentures, considerable effort is required to manage the implants. Implants or dentures may break because they are delivered as is to a few implants below In order to solve the shortcomings of the implant denture, the magnetic denture fixing device of the present invention used a magnet pulling force with each other as a method for fixing the denture to the gum. In other words, two magnets are planted in the alveolar bone and the other is planted in the denture so that when the dentures are installed on the gums, the magnets are fixed to the gums using the force of pulling the magnets together. The advantages of magnetic denture fixtures over conventional implant dentures First, the structure is simple and durable (usually two magnets) Secondly, the procedure is simple and the duration of the procedure is short (no bone adhesion period is required, such as when fixing an implant, and it is usually screwed or glued) Third, less damage to the jawbone (including alveolar bone) compared to the implant dentures, less damage to the jawbone Fourth, since there is no protruding part on the gum like the abutment of the implant, there is little possibility of infection and it is easy to manage after the procedure. Fifth, since the pressure when chewing food is transmitted directly to the alveolar bone denture fixing device 10 rather than directly through the gums, there is little risk that the denture fixing device is broken by the pressure when chewing. Sixth, when using dentures, simply place the dentures on the gums, and the dentures are fixed to the gums by the force of the magnet.기존의 틀니는
