摘要：
The invention relates to dentistry and can be used as an anesthetic device for blocking the mental and incisal branches of the lower alveolar nerve during dental procedures. A device for mental anesthesia according to C. Malamed, placed when used in the oral cavity, characterized in that the body 1 is designed as an arcuate frame 9, which contributes to the vestibular aspect of the lower lip and the angle of the mouth to the vestibular side to improve visualization of the transitional fold area determination of the injection site, containing the rear middle wall with a graduated scale 6, in front of which the adjusting bar 5 is moved by means of the adjusting screw 4, and with the reverse one It has a bracket for installing an additional adjusting screw 7 with a supporting platform 8 designed to be located on the chewing surface of the lower premolars, which is necessary when taking into account the height of the clinical crown of the tooth, and the spring-loaded clamp 2, designed as a handle 2a, movably mounted on a rotary support, and the lower the end has a curved edge 2b, which repeats the anatomical shape of the premolar neck, while the posterior middle wall on the reverse side is also provided with a curved edge that repeats the anatomical th shape of the neck of a premolar, which improves the fixation device in the neck of the lower premolars and makes it possible to use the device as a right or left side. Using this utility model allows you to determine the topography of the target point during mental anesthesia and contributes to a more accurate summing of the tip of the injection needle to the mental aperture, where the neurovascular bundle is located before entering the mental aperture, and increases the anesthetic effect. 6 Il.Полезная модель относится к стоматологии и может быть использована в качестве анестезиологического устройства для блокады подбородочного и резцовой ветви нижнего луночкового нервов при проведении стоматологических вмешательств.
