Abstract
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).
Claims15
A dental prosthesis comprising
- a prosthesis base, and
- teeth which are attached to the prosthesis base,
- wherein the prosthesis base comprises a ventilation element,
- wherein the ventilation element comprises a ventilation valve,
- wherein the ventilation valve is combined with a bleed valve,
- wherein both the ventilation valve and the bleed valve close automatically under pretension and only the ventilation valve may be opened by manual actuation, and
- wherein a valve body of the ventilation valve and the bleed valve ends in a valve body lip which extends on a tooth side of the prosthesis base and covers and closes the valve opening in the manner of a suction cup lip.
4 more elements
The dental prosthesis as claimed in 1,
- wherein the valve body lip is lifted from the prosthesis base upon application of pressure to an actuation element of the valve body from the tooth side of the prosthesis base and opens the valve.
A retrofit kit for a dental prosthesis comprising
- a prosthesis base having a valve body which is configured to be inserted into a valve opening to be installed in the prosthesis base, and is attachable thereat by adhesive bonding or polymerization, and
- wherein the valve body is a ventilation valve combined with a bleed valve,
- wherein both the ventilation valve and the bleed valve close automatically under pretension and only the ventilation valve may be opened by manual actuation, and
- wherein the valve body of the ventilation valve and of the bleed valve ends in a valve body lip which extends on a tooth side of the prosthesis base and covers and closes the valve opening in the manner of a suction cup lip.
1 more element
A retrofit kit for a dental prosthesis comprising
- a prosthesis base having a combination of a valve body with a valve seat which are prefabricated such that they match one another,
- wherein the valve seat is configured for installation in a bore configured for installation in the prosthesis base and is attachable thereat by adhesive bonding or polymerization and
- wherein the valve body is a ventilation valve combined with a bleed valve,
- wherein both the ventilation valve and the bleed valve close automatically under pretension and only the ventilation valve may be opened by manual actuation, and
- wherein the valve body of the ventilation valve and of the bleed valve ends in a valve body lip which extends on a tooth side of the prosthesis base and covers and closes the valve opening in the manner of a suction cup lip.
