METHOD OF ATRAUMATIC APEX REMOVAL OF TOOTH ROOT (VERSIONS) Russian patent published in 2020 - IPC A61C3/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical dentistry and maxillofacial surgery, and is intended for use in removing apex of a tooth root. Root dislocation is performed with the luxator. At that, wire from bioinert material is inserted into the socket of the removed tooth until it stops into the occlusal surface of apex of the tooth root; bending of wire above vestibular edge of socket in direction of apex of tooth root is performed until it adjoins the oral mucosa of the oral cavity of the alveolar process or the alveolar portion of the jaw to form a wire staple with the vestibular and oral arms; vestibular arm of wire brace is cut off to length equal to sum of lengths of oral arm of staple and apex of tooth root; dosed manual pressure is punctured distally or medially, or apically relative to the end portion of the vestibular arm of the wire staple through the oral mucosa, submucosal layer, periosteum, outer cortical plate, spongy substance of alveolar process or alveolar part of jaw in projection of apex of tooth root by flat cutting edge of straight luxator perpendicular to external cortical plate to form wound channel with diameter equal to diameter of intermediate part of luxator; flat cutting edge of the direct luxator through the wound canal or simultaneously with formation of the wound canal is introduced into the periodontal slot or bone tissue distally or medially, or apically to the apex of the tooth root, the luxator is rotated along longitudinal tool axis by 90° resting on basal jaw in wound canal before apex dislocation in occlusal direction. Also, the end portion of the vestibular arm of the wire clip is bent to an annular guide diameter equal to or greater than the width of the flat cutting edge of the straight luxator; dosed manual pressure is punctured through annular guide vestibular arm of wire clip through oral mucosa, submucosal layer, periosteum, outer cortical plate, spongy substance of alveolar process or alveolar part of jaw in projection of apex of tooth root by flat cutting edge of straight luxator at an angle of up to 30° to an external cortical plate to form wound channel with diameter equal to diameter of intermediate part of luxator; flat cutting edge of the straight luxator is inserted through the annular guide of the vestibular arm of the wire clip and the wound canal or simultaneously with formation of a wound canal into the periodontal slot or bone tissue distally or medially, or apical to a root apex, the luxator is rotated along longitudinal tool axis by 90° resting on basal jaw in wound canal before apex dislocation in occlusal direction.

EFFECT: method provides minimizing a soft tissue injury and prevents occurrence of fractures of jaw and dental root walls, creates conditions for preservation of trophism of surrounding tissues, and also reduces time of surgical intervention, minimized risk of injuries of adjacent teeth and surrounding tissues.
