HOLDING DEVICE FOR A DENTURE OR BASE STRUCTURE MODEL

摘要

The invention relates to a holding device (56) that can be braced in a surveying machine together with an individual preparation model (22) produced by dental laboratory techniques. The holding device (56) has a mechanically stable frame (10) with bores (12) disposed at a distance (a) to one another, in which at least two holding pins (18) are locked that can be displaced at least in the axial direction (A). The holding pins (18) are linked on the front thereof with the preparation model (22) that is free of undercuts by means of a primer (34) and they fixate the model rigidly and without tension in the frame (10). The loaded frame (10) can be braced in the surveying machine by means of a machine-side bracing adapter (16) in an anti-skid and rotationally fixed manner. The preparation model (22) and the frame (10) are fixated outside the surveying machine. The number and position of holding pins (18) is determined, the pins are inserted in the respective bores (12), the primer (34) is applied to the front of the pins and the pins are placed on the surface of the preparation model (22) and all holding pins (18) are locked so that they cannot be displaced or rotated. The loaded holding device (56) is exposed once the primer (34) is cured.
