VESTIBULOPLASTY METHOD Russian patent published in 2024 - IPC A61B17/24 

FIELD: medicine; surgical dentistry.

SUBSTANCE: invention is intended for use in vestibuloplasty to create a wide area of attached keratinized gums in the area of teeth and dental implants. Under local anesthesia using a scalpel, located at an acute angle to the surface of the alveolar bone, performing a linear horizontal incision in a zone of attached keratinized gingiva, parallel and 1–2 mm from the coronary mucogingival line to the periosteum along the group of teeth with subsequent mobilization of the mucous-muscular flap without disturbance of periosteum integrity with application of laser radiation at wave length 445±40 nm in pulse mode by non-contact method. Apical edge of incision is moved apically with fixation of flap edge to periosteum with non-resorbable suture to depth, allowing to create a zone of fixed tissues of at least 10 mm, using a continuous suture, made so that the first prick of a needle with a suture is carried out through an apically displaced mucous-muscular flap from its outer side, having retreated from the flap edge by 1.5–2 mm, the second needle is pricked into the periosteum, the needle with the thread is horizontally passed through the subperiosteal space, the needle with the suture is brought out from the subperiosteal space by sticking the needle into the inner surface of the periosteum. First needle stick point located at the edge of the apically displaced flap, is projected to the middle of the distance between the points of insertion and withdrawal of the suture from under the subperiosteal space, wherein the first prick of the needle is alternated from the outer and inner sides every 5–6 mm, at which from the outer side of the apically displaced mucous-muscular flap the needle with the suture is carried out at the initial and final stitches of the continuous suture, and formation of fixation of continuous surgical suture in two points by means of 3 knots is performed by 3 turns of suture around branches of needle holder. Continuous suture is removed not earlier than 21 days of the postoperative period. 5–0 synthetic non-resorbable suture of polypropylene is used to fix the flap edge to the periosteum.

EFFECT: method, by providing hemostasis in the area of the surgical field, maintaining the apically displaced mucous-muscular flap in a given position and stability of the plastic surgery result, allows to increase efficiency of surgical intervention at creation of wide zone of attached keratinized gum in area of teeth and implants of teeth.
