Abstract

A process for documenting the position of a dental casting model relative to the mold surface is distinguished by the fact that the position of the model on the gate molder is pictorially recorded prior to it being embedded. This is expediently done simultaneously to the pictorial fixing of a marking which reproduces the position of the surface of an assigned mold in relation to the cast object or to the gate molder. This can be a marking which is physically connected to the gate molder. However, it can also be contained in the recording instrument or stored in the analyzing unit of the recording instrument. Where different sizes are used, the assignment of the respectively pertinent marking to the gate molder of predetermined size can be realized automatically. Instead of the use of such a marking, it is also possible additionally to take a pictorial record of the mold following the embedding, in order to be able to interrelate the position of the object and the position of the mold surfaces by comparing the records prior to and following the embedding. Instead of this, it is also possible to document the model in the actually used muffle mold shell or to document the model or the…
