METHOD FOR THIXOTROPY TESTING OF DENTAL MATERIALS AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2010 - IPC A61C13/38 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment and can be used in orthopaedic dentistry for thixotropy testing of cast dental materials. A device for thixotropy testing of the cast dental materials comprises a transparent cylinder wherein in its top, there is a piston with a rod, and thereunder there is a limiter with a capillary directed to a cylinder bottom to form a chamber for the cast dental material between the piston and limiter; a load tank with a cover mounted on the opposite side of the rod. The transparent cylinder is fixed in an opening of the frame fixed on a base. On the piston rod, there is a stopper for the piston stroke limitation. The transparent cylinder, stopper and capillary are calibrated in mm. The method implies that with using a device under cl.1, triple pressure of one weight load is exerted on equal volume of each analysed cast material.

EFFECT: ensured adequate comparative thixotropy testing of cast dental materials.
