DEVICE FOR MAKING IDENTICAL EXPERIMENTAL CONSTRUCTIONS OF TEMPORARY FIXED DENTURES Russian patent published in 2014 - IPC A61C13/20 A61C13/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to dental orthopaedics, and aims at analysing the strength properties of temporary fixed dentures. A device for making identical experimental constructions of temporary fixed dentures consists of two mated rectangular box-shaped units and a stamp. The box-shaped units are made of a low-melting metal; an inner surface of each unit has a profile of a negative image of the construction of the temporary fixed denture longitudinally, and triangular saw cuts extending from occlusion surfaces of the negative image of each crown denture passing to the end surface of the box-shaped units. The inner surfaces of the box-shaped units have retention guides in the form of triangular spines on one unit and in the form of triangular recesses on the other one. Each of the end surfaces of the units projecting on the surface of abutment teeth has a profile of a positive image of prepared stumps. The stamp is made of a low-melting metal and has a profile of the positive image of the prepared stumps and prosthetic bed.

EFFECT: invention enables making the identical temporary dentures of various lengths made of various structural materials.
