The utility model relates to dentistry and can be used as an anesthetic device for blocking the lower hole of the nerve during dental interventions. A device for determining the width of the branch of the lower jaw containing an arched body with an extraoral and intraoral parts, characterized in that the extraoral part is made in the form of a plate arc 1 with an end section with a groove 3, and a fixed ring-shaped grip 2 for the finger is installed on the outer bend of the body, and the intraoral part includes a measuring rod 7 with a graduated scale and a holder 8, and the end part of the rod is made in the form of a saddle 9, while the rod 7 is movably mounted along the through The pressure channel 5 is in the housing 4 and is held by means of a screw lock 6, for which it is equipped with an additional elastic element 10 supported between the end saddle 9 of the rod and the housing 4. Using this utility model, it will be possible to quickly and accurately determine the width of the lower jaw branch, measured by means of a graduated rod. Moreover, the device is universal for measuring the width of the lower jaw branch on both the right and left sides. Such an approach determines individual anatomical and topographic features of the width of the branch of the lower jaw, which are taken into account when performing mandibular anesthesia, which is necessary to increase the efficiency and safety of anesthesia associated with the exclusion of trauma of the mandibular neurovascular bundle. 1 tablet, 6 ill.Полезная модель относится к стоматологии и может быть использована в качестве анестезиологического устройства для блокады нижнего луночкового нерва при проведении стоматологических вмешательств.
