METHOD FOR VESTIBULOPLASTY Russian patent published in 2019 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical dentistry, and can be used in vestibuloplasty. Vestibular cavity is formed by cutting along mucogingival junction. Incision along the mucogingival junction is started and completed in zones with a normal width of the attached gum. Incision is made to a depth of the mucous layer along the border of an attached keratinized gum and a movable mucous membrane. Muscular bands are separated from the periosteum so that the depth of the prepared vestibule is deeper than the required depth by no more than 20 %. Edge of the mucous membrane is displaced apically to the obtained depth and fixed to the periosteum with horizontal mattress sutures using resorbable threads 5-0. Autograft is divided along S-shaped linear incision into two symmetrical fragments. One of the ends of the fragments has a width corresponding to the width of the normally attached gum; the width of the second, narrow ends of the fragments is not less than 1.5 mm. Obtained fragments are placed along the deepest part of the prepared vestibule. Wide ends are fixed along edges of wound to attached gum with normal width of nonrebiable monofilaments 6-0. Artificial membrane for closing an open periosteum is a polymer phospholipid matrix that is a two-layer film with an internal rough and an external relief surface. Matrix is modeled by defect shape and laid with rough layer on wound. Then it is fixed along external edges with non-resorbable monofilaments 6-0 with interrupted sutures. Over the pressing seams are applied. Donor palatal region is closed with a phospholipid matrix. Sutures are removed by the end of the second week.

EFFECT: method provides creating conditions for uniform cell proliferation along entire wound surface, obtaining a fixed depth of a vestibule and an increase in the width of the area of the attached keratinized gum in conditions of its almost complete absence in separate areas in the area of teeth and implants with a minimum risk of infection, reducing the size of the defect of the donor area, improving the aesthetic effect and reducing the length of treatment by using autografts, a polymer phospholipid matrix and a method for using them.
