Rubber dam

A rubber-dam comprising

• a flexible cover foil for covering an oral cavity, wherein said cover foil has, in a relaxed state, the shape of a bag and
• at least one groove in said cover foil for marking a preferred cutting position in an incisial/occlusal area thereof.

A rubber dam comprising:

• a flexible cover foil for covering an oral cavity in the form of a patient's mouth, the patient's mouth having an upper and lower vestibule, upper and lower lips and two cheeks, wherein said cover foil has, in a relaxed state, the shape of a bag that is closed laterally and at a first end,
• a frame for being located outside the patient's mouth circularly around the patient's upper and lower lips, wherein an outer margin of said cover foil at a second end opposite the first end is connected to the frame, and
• arc-shaped first and second retaining members made from a firmer material than said cover foil, said first retaining member suited for being arranged in the upper vestibule of the patient's mouth and said second retaining member suited for being arranged in the lower vestibule of the patient's mouth, wherein said first and second retaining members are interconnected for generating vertical tensional forces.

A rubber-dam comprising:

• cover means comprising a flexible cover foil for covering an oral cavity in the form of a patient's mouth, the patient's mouth having an upper and lower vestibule, upper and lower lips and two cheeks, wherein said cover foil has, in a relaxed state, the shape of a bag that is closed laterally and at a first end,
• an affixing device with a, compared to the cover means, firmer holder means for pressing the cover means against the oral cavity of the patient, and a rubber-dam frame arranged circularly around the affixing device,
• wherein said affixing device comprises arc-shaped first and second retaining members made from a firmer material than said cover foil, said first retaining member suited for being arranged in the upper vestibule of the patient's mouth and said second retaining member suited for being arranged in the lower vestibule of the patient's mouth, wherein said first and second retaining members are interconnected for generating vertical tensional forces.
