ABSTRACT:
A dental cap for the veneer of a jacket crown comprising a noble metal foil in substantially frusto-conical shape, which starting from a substantially circular foil piece is formed by folding the outer region in the direction towards the axis of rotation to form overlappings, the outer region of the foil piece being divided into flaps and the overlapping regions being joined inseparably together. For dividing the outer region two different types of cuts are made from the outer edge in the direction towards a surface area disposed in the center and as a result of said cuts the dental cap is completely closed in the side wall region by overlappings there.
