METHOD FOR SIMULTANEOUS VESTIBULOPLASTY AND TREATMENT OF GENERALIZED GINGIVAL RECESSION Russian patent published in 2024 - IPC A61B17/24 A61C8/02 A61K35/16 A61P1/00 A61K38/19 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical dentistry and periodontics. Local anaesthesia is performed with infiltration anaesthesia in the area of the small vestibule and recession of the gum and in the area of graft sampling on the hard palate. Submucosal graft is sampled from the donor area on the hard palate and the donor area is closed. Mucous membrane of the lip is incised parallel to a curvature of the lower jaw at distance of 9–12 mm from the mucogingival line in the region from canine to canine and 7–10 mm in the region of premolars and molars. Mucous flap is detached from the incision line to the jaw. Submucosal tissues are moved along the jaw periosteum to depth of 9–12 mm in the frontal portion, and by 6–7 mm in the lateral portions of the lower jaw. New depth of the oral vestibule is formed by performing a coronal displacement towards the apex of the teeth of the mucous flap and soft tissues in the area of the teeth with gingival recession, while maintaining the integrity of the gingival papillae. Patient’s venous blood is pre-sampled in a vibration-free centrifuge by the PRF or APRF technique and an automembrane is created. During the operation, the mucous flap is detached from the incision line to the jaw without intrusion into submucosal tissues of the inner surface of the lip. Combined mucosal flap is formed. Automembrane PRF or APRF is placed under the coronal displaced mucous flap of the combined mucosal flap, laying it on the jaw bone so that the surface of the exposed bone is covered and the newly formed vestibule is stabilized. Previously produced graft is placed under the coronal displaced full-thickness flap of the combined mucosal-full-thickness flap and a buccal flap, placed on the surface of the most exposed roots. Horizontal sutures are applied to fix the coronal displaced mucous flap in a new position, as well as interdental sutures to stabilize the moved tissues coronal. Wounds are closed and fixed. Anti-inflammatory and antibacterial treatment is prescribed. Wound is closed and additionally fixed with Superlimph alginate plates.

EFFECT: method enables to simultaneously eliminate generalized gingival recession and perform vestibuloplasty in patients with dentoalveolar malocclusion, modifying the biotype of the structure of soft tissues of periodontium with eliminating the risk of recurrences of the disease, provide an optimal amount of attached and keratinized gums in the area of teeth with a gingival edge recession, accelerate healing by reducing a probability of developing infectious complications.
