Device for producing dental jaw models in the form of saw cut models, and construction kit therefor

摘要

The invention relates to a device for producing dental jaw models in the form of saw cut models, impression trays of various sizes for upper jaw and lower jaw being provided with guides or grooves at their opening rim, such that a base rim with a marking relief can be attached in a flush and interlocking manner at right angles to the upper plane of the base rim, while separating plates are received in guide grooves which plates are individually contoured such that they serve as intended breaking points for the production of individual stumps which surround a pin which has previously been introduced, in a manner corresponding to the impression position, at right angles in a support plate in the position which corresponds to the centre of the model stump to be produced, the support plate having at least one arc-shaped row of preshaped perforations which are arranged centrically to the rim of teeth or are individually bored, and, in addition, carrying one or more positive webs or negative guides which render the individual stump rotationally stable, the support plate being formed such that it is adapted to suit the base rim via a guide on the side lying opposite the impression tray, and grips circularly around this guide. <IMAGE>
