Description

Technical Field

[0001] The utility model relates to the technical field of oral medical treatment, in particular to a novel split-type movable denture. Background Art

[0002] In daily life, our teeth will experience slow physiological wear when chewing food. With the increase of age, as well as factors such as bad chewing habits and bruxism at night, the wear will increase day by day. At present, our solutions for repairing edentulous and missing teeth are mainly based on removable dentures. The professional name of removable dentures is removable dentures, including removable partial dentures and full dentures. They use the remaining natural teeth, the mucosa and bone tissue under the base as support, rely on the denture's retainers and base for retention, use artificial teeth to restore the shape and function of missing teeth, and use base materials to restore the defective alveolar ridge, jawbone and its surrounding soft tissue morphology. Patients can take it off and put it on by themselves.

[0003] For example, the "New Split-Type Removable Denture" with publication number CN209933029U includes a base body and a tooth body, the top of the base body is provided with a tooth socket matching with the tooth body, the lower end side of the tooth body is provided with a step portion 1, the inner wall of the tooth socket is provided with a step portion 2 matching with the step portion 1, the bottom of the tooth body is provided with a boss, the bottom of the tooth socket is provided with a groove matching with the boss, the bottom of the boss is provided with a socket, the groove is provided with a rod matching with the socket, and the groove is provided with a spring, the bottom end of the spring is fixedly provided on the bottom surface of the groove, and the top end of the spring is fixedly provided with a pressure sensor. By arranging the step portion 1, the step portion 2, the boss, the groove and the spring, the problem that the traditional removable denture tooth body and the base body are not tightly connected and the tightness of the tooth body is difficult to evaluate in time is solved.

[0004] Although the above-mentioned removable dentures have certain advantages in installation and fixation, they still have certain disadvantages:

[0005] When using the above dentures, after a long period of continuous occlusion, the crowns of the dentures are worn and damaged, thus affecting their use. When replacing, the above dentures need to be replaced, and it is impossible to replace them alone or replace the crowns, which causes waste, increases the loss of money, and is inconvenient for subsequent maintenance and use.

This setting can effectively prevent food residues from entering the crown 5.

[0027] Here’s how it works:

[0028] First, when using, the patient puts the base 2 on the gum 1 and uses the tooth hook 3 to fix it on the existing teeth to complete the installation of the denture;

[0029] Second, after long-term use, the crown 5 is damaged due to repeated bites, which affects the use and needs to be replaced. The adjusting plate 671 is rotated to make the adjusting plate 671 vertical, and then the adjusting plate 671 is pushed. When the adjusting plate 671 moves, the movable rod 62 is moved. When the movable rod 62 moves, the adjusting rod 63 is moved. When the adjusting rod 63 moves, the spring 65 is squeezed.

[0030] Third, the old crown 5 is then taken out, and when the crown 5 moves upward, it pushes the limit block 661 to move toward the groove of the adjustment rod 63;

[0031] Fourth, place the new crown 5 along the fixing rod 61, then loosen the adjusting plate 671, and the spring 65 releases its elastic potential energy after losing its force, pushing the adjusting rod 63 to move. When the adjusting rod 63 moves, it pushes the limit block 661 to move toward the limit groove 662, so that the limit block 661 fixes the crown 5, and then rotate the adjusting plate 671 to make the adjusting plate 671 in a horizontal state, and the installation of the crown 5 is completed.

[0032] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0033] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
