METHOD AND FORCEPS FOR REMOVING DENTAL CALCULI Russian patent published in 2007 - IPC A61C3/00 

FIELD: medicine.

SUBSTANCE: method involves applying forceps. Distance between clearer blade and lower branch support surface is set and the support surface is placed on the dental chewing surface. The clearer blade is brought close to the lateral tooth surface under calculus base deviating ginigiva aside and lightly pressing blade edge to the tooth. The branches are pressed together and calculus is removed. Tooth surface is processed all around in rotating the clearer blade about its axis. The forceps has lower branch connected to the upper one by means of hinge. The clearer blade is fixed in the upper branch passing into hole in lower branch plate thrusting against tooth. The branches are tubular, the clearer blade and its socket in the upper branch have curl or thread on the end opposite with respect to the blade so that the clearer blade is rotatable about its axis and no longitudinal spontaneous displacement is allowed. The clearer blade is fixed with screw movable in the upper tubular branch via internal thread to clamp the clearer blade in curl or thread zone. The hinge is designed as flexible member and the clearer blade is placed in perpendicular to the clearer blade axis.

EFFECT: improved mechanical conditions in pressing clearer blade against lateral tooth surface.
