The invention refers to a fabricating method for one-piece cast dental crowns, with controlled thickness, as well as for dental bridges consisting of crowns and the bridge body. To this end a calibrated wax cylinder is placed on the tooth stump, this cylinder being flared in order to form proximal contact points with the adjoining teeth, thus realizing practically also the control of thickness; over the wax cylinder a lid is applied at the level of the occusal surface and in which the occlusal relief is fashioned in relation to the contact points of the antagonistic teeth. In the case of dental bridges, the patterns of the respective crowns are fashioned first, as above, then the pattern of the bridge body which is united with the pattern of the crowns, after which follows the casting of the entire assembly from a gold alloy.
