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.

Abstract: Arrangement for joining denture components by adhesion, in particular a prosthesis component with an anchoring or bedding part. It consists of a pair of connecting elements or model parts for connecting elements which are joined to or can be joined to the components to be joined and at least one of which encloses the other. So that the join can be closed without the danger of thermal distortion with correctly prepared individual components--if appropriate even in the mouth of the patient--the surfaces to be joined on the connecting elements or the model parts have an intermediate space which allows positioning of the components to be joined and can be filled with sealing compound which hardens, the surfaces comprising surface portions cut away in respect of the direction of loosening and hence acting on the sealing compound in a positive manner.
