Abstract
A removable denture for an oral cavity of a human is disclosed. The removable denture includes a denture body and a supporting base. The supporting base is attached to mucosa on an edentulous alveolus and on palatine bones in the oral cavity. The denture body is joined to the supporting base. The denture body comprises a denture teeth for chewing. A central region of the supporting base is less flexible than a periphery region of the supporting base so as to maintain a high adhesion of the periphery region to the mucosa when the oral cavity is in chewing. The supporting base comprises an on-way venting device capable of improving the negative pressure effect between the supporting base and the mucosa so as to prevent the supporting base from falling off.

- and
- a supporting base comprising a first contact surface and a second contact surface opposite to the first contact surface;
- wherein the second contact surface is adapted to attach to mucosa on an edentulous alveolus and on palatine bones in an oral cavity, and when a central region and a periphery region surrounding the central region are defined on each of the first contact surface and the second contact surface along an occlusion direction, the central region of the first contact surface is joined to a central region of the mucosa-faced surface of the denture body, the periphery region of the first contact surface is detachably attached to a periphery region of the mucosa-faced surface of the denture body, and flexibility of the periphery region is greater than flexibility of the central region.
