METHOD OF BONE GRAFTING WHEN REMOVING IMPACTED LOWER THIRD MOLAR Russian patent published in 2023 - IPC A61B17/56 A61K6/74 A61P1/02 A61C3/14 

FIELD: medicine; surgical dentistry.

SUBSTANCE: after local anesthesia, an intrasulcular incision is made in the area of the second molar of the lower jaw to its distal surface. A vertical incision is performed in the distal and lateral direction towards the branch of the lower jaw. The muco-periosteal flap is exfoliated. The impacted lower third molar is removed. Curettage of the bone cavity is performed and filled with osteoplastic material based on octacalcium phosphate. The edge of the mucoperiosteal flap adjacent to the distal surface of the second molar is mobilized and de-epithelialized. A needle with a thread is injected into the base of the gingival papilla from the vestibular surface between the first and second molars on the intervention side. A puncture is performed from the lingual surface of the gingival papilla and an injection is made through the lingual mucosa at the level of the distal surface of the second lower molar. The vestibular flap is pierced through in the zone of de-epithelialization from the inner surface. Injection is performed through the mucosa lingually at the level of the distal surface of the lower second molar. An injection is made into the base of the gingival papilla from the lingual surface between the first and second molars of the lower jaw and an injection is made from the vestibular surface of the gingival papilla at a distance of 3–5 mm from the free edge of the thread. At the same time, the free threads are tensioned by pulling the edge of the mucoperiosteal flap under the mucosa from the lingual surface in the region of the second molar. A surgical knot is tied. On the distal part of the incision, 1 simple interrupted suture or 2 simple interrupted sutures are placed at a distance of 3 mm from each other.

EFFECT: method makes it possible to prevent the formation of a periodontal pocket in the region of the lower second molar after the removal of the impacted third molar.
