METHOD OF MENTAL ANESTHESIA FOR BLOCKADE OF THE MENTAL AND INCISOR BRANCH OF LOWER LUNAR NERVES Russian patent published in 2019 - IPC A61M19/00 A61M25/14 

FIELD: medicine.

SUBSTANCE: invention refers to dentistry and can be used as an anesthesia device for blocking of incisor branch of lower lunar and mental nerves during dental interventions. Method for mental anesthesia for blockade of the mental and incisor branch of the lower lunar nerve, in which a device is used, comprising a body in the form of an arc-shaped frame, comprising a posterior middle wall with a graduated scale, in front of which there is a movable limiting plank, which is adjusted by means of a screw, and on the reverse side is made with bracket for installation of additional adjusting screw with support platform and spring-loaded clamp, made of handle, movably installed on rotary support. Lower end has a curved edge repeating the anatomical shape of the premolar neck. Posterior middle wall on the reverse side is equipped with a curved edge repeating the anatomical shape of the premolar neck; for this purpose, the device is inserted into the oral cavity in the area of the lower premolars. First, premolar is fixed on chewing surface of additional premolar by additional support screw, and arch-shaped frame of body front part is located in area of transient fold for displacement of lower lip and angle of mouth to vestibular side. Thereafter, the lower end of the clamp is inserted in the lower region of the premolar lower region by adjusting with an additional screw, and the movable limiting plate is set on the level of the chewing tooth surface with due allowance for the distance between the chewing surface and the mental canal. For anesthesia, a prick is pricked into a transient fold in the projection of the mental canal vertically in the premolar region and immersed until contact of the needle cannula with the surface of the movable limiting plate, which corresponds to the distance between the chewing surface and the mental canal, and an aspiration test is performed and an anesthetic depot is created, after which the syringe and the device are removed from the oral cavity, releasing the clamp handle.

EFFECT: use of the invention provides higher safety and effectiveness of mental anesthesia by accurate determination of the target point topography depending on the individual characteristics of the patients.
