METHOD FOR MAKING INDIVIDUAL IMPRESSION FOR ORTHOPEDIC INLAY Russian patent published in 2021 - IPC A61C5/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to dentistry, and is intended for use in the restoration of the crown part of the tooth. When making an individual silicone impression, an impression of the tooth stump and root canal is formed from a liquid corrective silicone mass, which is obtained by mixing the activator and liquid silicone corrective mass until homogeneity. The corrective silicone mass is injected into the root canal by means of a disposable syringe through a cannula. The first part of the mass is filled with a part of the root canal, previously developed for 2/3 of its total length. Then a paper pin with a taper of 02-06 is inserted into the root canal until it stops. The end of the post is left protruding beyond the edge of the coronal portion. The cavity of the tooth stump around the post is filled with the remainder of the liquid silicone corrective mass. A tooth stump is modeled, and after polymerization of the corrective mass, an individual impression of the orthopedic inlay is removed from the cavities of the tooth and the root canal for the protruding end of the pin. After removing the impression, the protruding end of the pin is cut off.

EFFECT: invention allows simplifying accurate modeling of the inner surfaces of tooth cavities and root canals.
