摘要：
FIELD: medicine.SUBSTANCE: invention refers to dentistry and can be used as an anesthesia aid in mandibular anesthesia accompanying dental interventions. Method of mandibular anesthesia is characterized by using a device comprising an arched body with extraoral and intra-oral parts. Extraoral part is made in the form of plate-like arc with end section with groove, on external bend of housing fixed ring-shaped grip for finger is installed. Intra-oral portion comprises a measuring rod with a graduated scale and a holder, wherein the end portion of the rod is in the form of a saddle, wherein the rod is movably installed along the through guide channel in the housing and is retained by means of the screw retainer, and additionally is equipped with an elastic element resting between the end seat of the rod and the housing. Anesthetic is fixed by fixing the end section of the arc with the extraoral part groove at the posterior edge of the mandible branch within the maximum concavity, after which the graduated rod is placed in the oral cavity, pulling back behind the holder. Rod end saddle is placed on the front edge of the mandible branch in the area of maximum concavity thus fixing the rod in the preset position by means of a fixator. Then, the device is removed from the oral cavity, the mandibular branch width is recorded, by which the optimal depth of the needle immersion is determined by calculation, which value is established on a line of the device for mandibular anesthesia by means of a movable limiter, and safe mandibular anesthesia is performed. For this purpose, the prepared device for mandibular anesthesia is placed in the patient's oral cavity within the maximum concavity of the front edge of the lower jaw branch until reaching the anvil. Device handle is located vestibularly from dental arches, moving angle of mouth and cheek outside to level of interocclusal height with open mouth, after which cartridge syringe with anesthetic and needle are installed parall
