Combined movable denture

Abstract

The invention provides a combined movable denture suitable for being worn on a human oral cavity. The combined movable denture includes an appearance member and a support base, the support base is adapted to be attached to the oral mucosa of the alveolar part and the palatal portion within the human oral cavity. The appearance member detachably connects with the support base. The appearance memberhas artificial teeth for the user to chew. The peripheral area of the support base is more flexible than the central area thereof, such that the peripheral area of the support base remains attached to the oral mucosa while the oral cavity exercises. Skirt enclosure can thus be ensured. The support base further includes a one-way valve to increase negative pressure effect while the oral cavity isexercising under the circumstances of skirt enclosure. Support base is thus less likely to be loose. Therefore, the removable artificial tooth assembly of the present invention can have a better userexperience.

Description

technical field [0001] The invention relates to a removable denture. Background technique [0002] The current full-mouth removable dentures are worn in the edentulous upper or lower jaw, mainly relying on the adhesion of saliva between the artificial full-mouth removable dentures and the oral mucosa, as well as the material of the removable dentures and the oral cavity. Friction between mucous membranes. However, during the chewing movement, the dentures of the upper jaw tend to fall off by themselves, and the dentures of the lower jaw are easy to dislocate and move. Some operators will create a concave circular space in the middle of the upper palate plate of the movable dentures. The negative pressure effect of the suction cup, but because it has not been designed for exhaust and decompression, it will not produce a vacuum-negative pressure effect, and theoretically it will not produce the negative pressure effect of the suction cup Install an exhaust device in the spac...

Problems solved by technology

[0006] Another example is the full-mouth movable denture of China Taiwan Patent Publication No. 200901942. The method of the 200901942 case is to install a sucker device at the bottom of the full-mouth removable denture. This method will cause damage to the oral cavity after long-term use, and the most direct damage is to cause oral cavity damage. The hyperplasia and deformation of the mucous membrane, that is, the oral mucosa at the suction cup will produce a bulge, and finally when the bulge is large enough to fill the space of the suction cup negative pressure cavity, the suction cup will lose its effect

In addition, theoretically, the stability of the removable dentures in the oral cavity can be divided into three functions: retention, stabilization, and support. A suction cup, and this makes the substrate unable to fit most of the area occupied by the suction cup in the oral cavity. Therefore, although the suction cup can increase the retention of the adsorption effect, but due to the reduction of the attachment area, the total removable denture The stabilizing effect and supporting effect are reduced. In summary, the practice of the 200901942 case needs to be improved, especially the protuberance hyperplasia and deformation of the oral mucosa
