Technical result is achieved by the following: device for gutta-percha pin calibration contains scalpel and case with calibration holes. Calibrating holes are located along the length and are provided with indicators of diameter and length scale with millimeter points. Scalpel is made in form of spring-loaded from butt end plate of ""-shaped section with bent inwards and at angle not exceeding 45 to base shelves. Plate is made from stainless elastic steel and is installed by means of shelves in L-shaped slots of lower part of base on its length with possibility to travel. On plate wall rectangular holes are made. Rectangular holes are located on its length evenly and in accordance with calibrating holes with cutting edge on one side. ^ EFFECT: increase of calibrated gutta-percha pin quality and therefore treatment quality, reduction of time required for rod calibration and tooth root canal treatment. ^ 3 cl, 8 dwg |
