  • Patent number: 4380436
    Abstract: The invention relates to a support for retaining a removable dental prosthesis on the remainder of one's natural teeth. In accordance with the invention, a conical pin is mounted on the crown base of a capped tooth. A slotted conical bushing is mounted on a dental prosthesis which bushing is received in a telescopic manner on the pin. The pin and the bushing are so disposed that they are positioned vertically between the capped tooth of the remainder of the natural teeth and the adjacent tooth of the dental prosthesis. The bushing is provided with a spring element which yieldingly engages into recesses of the pin when the bushing and the pin are in total engagement with each other, thus retaining the dental prosthesis in its end position. By a corresponding force application, the yielding snap connection can be easily released, so as to remove the dental prosthesis.
