VESTIBULOPLASTY METHOD Russian patent published in 2024 - IPC A61B17/24 A61B18/20 

FIELD: medicine.

SUBSTANCE: invention relates to surgical dentistry. Under local anaesthesia, a linear horizontal incision of the oral mucosa is performed parallel and 0.5–1 mm apically from the mucogingival line to the periosteum along a group of teeth at least one. Mucous-muscular flap is mobilized without disturbing the integrity of the periosteum using laser radiation at wavelength 445 ± 40 nm with power of 1 W in pulse mode by contactless method. Apical edge of the incision is moved apically. Flap edges are fixed to the periosteum with a non-resorbable suture to a depth of at least 10 mm. Continuous suture is performed so that the first needle with a thread is inserted through an apically displaced mucous-muscular flap from its outer side, at distance of 1.5–2 mm from the flap edge; the second needle is inserted into the periosteum. Needle with a suture is passed horizontally through a subperiosteal space. Needle with the suture is brought out from the subperiosteal space by sticking the needle into the inner surface of the periosteum. First needle point located at the edge of the apically displaced flap is projected to the middle of the distance between the points of filament insertion and removal from under the subperiostal space. First prick in of the needle is repeated from the outer and inner sides every 5–6 mm. From the outer side of the apically displaced mucous-muscular flap, a needle with a suture is delivered at the initial and final stitches of the continuous suture. Continuous surgical suture is fixed at two points with help of 3 knots. Suture is made 3 turns around the branches of the needle holder. Continuous suture is removed not earlier than 21 days of the postoperative period. 5-0 synthetic non-resorbable suture from polypropylene is used to fix the flap edge to the periosteum.

EFFECT: method enables increasing the effectiveness of vestibuloplasty, providing hemostasis in the area of the operative field, holding the apically displaced mucous-muscular flap in the preset position.
