The invention relates to a dental prosthesis comprising a prosthesis base and teeth which are attached in or to the prosthesis base (14), wherein the prosthesis base (14) comprises a ventilation element, in particular a ventilation valve (12).

The invention relates for producing permanent dentures without using any implants (screws) on the gum or using glue but using the vacuum of suction cells (suckers), between the natural gum and dentures, but using flexible thin plastic (approved by FDA) sheath between the gum and the dentures using suckers (similar to octopus) made on upper and lower surfaces of the sheath the upper sheath surface will have the same shape of the normal denture lower surface, similarly the lower sheath surface will have the same shape of the gum, the shape of the plastic sheath will always have the same shape of the gypsum modeled cast at the dentist clinic, for the gum surface, all the suckers will be (squeezed) pressed and create vacuum to hold the dentures to the gum and the dentures.

A denture-securing device is provided that is usable to substantially secure a denture within a mouth. The denture-securing device may be used with top dentures, bottom dentures, or other configurations of dentures. The denture-securing device may advantageously secure dentures without requiring use of adhesives. The denture-securing device may also reduce the likelihood of food getting under dentures, provide a firm yet soft and comfortable fit, and minimize rocking of lower dentures. The denture-securing device may advantageously be secured to gums using a suction fit through saliva or other sources of moisture.

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.
