The tooth crown is given the final shape by a veneer material attached to the external surface of the coping by e.g. firing of dental porcelain. To manufacture a tooth crown according to the method of the invention decreases essentially the manufacturing time for the tooth crowns and at the same time the strength and the accuracy to shape increase.
