METHOD FOR VESTIBULOPLASTY WITH SUPRABONY IMMOBILIZATION OF A FREE GINGIVAL AUTOGRAFT Russian patent published in 2022 - IPC A61B17/24 A61C13/00 A61C8/00 A61C3/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely surgical dentistry and maxillofacial surgery. Along the border of the keratinized and non-keratinized gums, a horizontal incision is made to the periosteum from the vestibular side of the mucous and submucosal layers. Next, the mucous membrane is split and moved apically. Then the movable mucous membrane is fixed at a new depth of the vestibule with a resorbed suture material. Next, a free gingival autograft is modeled. A strip of soft tissues from the patient’s hard palate is used as a free gingival autograft, and the length of the strip is more than twice the width. In this case, the strip of the free gingival autograft should have a rectangular shape around the perimeter with a uniform thickness over the entire area, and also contain epithelium, its own plate and fat layer. The resulting free gingival autograft is rigidly fixed directly to the bone for the entire length of the recipient area using bone titanium pins. At the same time, the fat layer of the free gingival autograft is removed before transferring it to the recipient area.

EFFECT: method makes it possible to replenish significant volumes of lost soft tissues with extensive defects using a minimum number of the patient’s autogenous tissues, achieve a functional, stable and high-quality result of keratinized motionless mucosa, keep the result stable without tissue loss in the delayed period, significantly reduce the level and area of trauma of the donor zone, prevent soft tissue necrosis and avoid violations of bone vascularization in the field of transplantation, to avoid mucosal recession, tissue inflammation, peri-implant mucositis, mucositis, peri-implantitis, bone destruction and implant loss, shorten the rehabilitation period, as well as facilitate independent home oral hygiene.
