Abstract: An arrangement of artificial teeth, preferably made of methacrylate, in which the teeth are mounted at the roots end in the natural sequence on a flexible plastic strip made of acrylate plastic in such manner that movement of the teeth in relation to each other is possible without their disengagement from said plastic strip. The arrangement is suitable for the manufacture of an artificial partial or total denture, in that on a preformed prosthesis in which a part of the teeth can already be contained on the complete prosthesis base, a fixing substance is applied to the free remaining part of said prosthesis base, and the dental arrangement is fitted into it.
