METHOD OF NON-TRAUMATIC APEX REMOVAL OF DENTAL IMPLANT (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 apex removal of a dental implant. A bone bed is created by the crestal approach to the occlusal surface of the apex fracture of the dental implant. A wire from bioinert material is inserted into the bone bed until it stops in the occlusal surface of the apex of the dental implant; bending of wire above vestibular edge of bone bed in direction of apex of dental implant to fit it to mucous membrane of oral cavity of vestibular surface of alveolar process or alveolar portion of jaw to form a wire staple with 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 dental implant; dosed manual pressure is punctured distally, or more medially, or apically relative to the end portion of the vestibular arm of the wire staple through the oral mucosa, the submucosal layer, the periosteum, external cortical plate, spongy substance of alveolar process or alveolar portion of jaw in projection of apex dental implant flat cutting edge of direct luxator perpendicular to external cortical plate with formation of wound channel with diameter equal to diameter of intermediate part of luxator; flat cutting edge of the direct luxator through a wound canal or simultaneously with formation of a wound canal is introduced into the bone tissue distally, or more medially, or apically than the apex of the dental implant, the luxator is rotated along longitudinal tool axis by 90° resting on the basal jaw in the wound canal until the apex of the dental implant is dislocated in the occlusal direction.

EFFECT: method provides minimizing a soft tissue injury and prevents occurrence of jaw wall alveolar fractures, creates conditions for preservation of trophism of surrounding tissues, shortens time of surgical intervention, preserves volume of bone and soft tissues.
