METHOD FOR MAKING PLASTIC REPAIR IN FRONTAL PART OF THE ORAL CAVITY Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves making cut along mucogingival boundary of the maxilla down to periosteum. The mucous membrane is detached in transition fold area. It is moved towards deeper oral cavity atrium fornix and sutured to periosteum. Wound surface is covered with bound flap taken from buccal area behind lip commissure. To form the flap, the first incision is made on the maxillary transition fold area behind lip commissure. The incision is continued downwards over the cheek 2-3 mm far from the commissure towards mandibular transition fold. The second incision is done in maxillary transition fold area 1 cm distal from the previous one. The incision is continued downwards over the cheek and connected to the first incision end. Mucosubmucous flap is detached beginning from the lower end. The formed flap width in the central region is to be equal to 1 cm. The flap is turned on the feeding pedicle at an angle of 90°, laid over the wound surface on vestibular side of maxillary alveolar process and fixed with sutures on mucous membrane edge. Another version of the method involves making incision along mucogingival boundary of the mandible down to periosteum. The mucous membrane is detached in transition fold area. It is moved towards deeper oral cavity atrium fornix and sutured to periosteum. Wound surface is covered with bound flap taken from buccal area behind lip commissure. To form the flap, the first incision is made on the maxillary transition fold area along projection immediately behind lip commissure. The incision is continued downwards over the cheek towards mandibular transition fold. The second incision is done in maxillary transition fold area from the beginning of the first incision. The incision is continued downwards over the cheek towards mandibular transition fold. Mucosubmucous flap is detached beginning from the upper end. The formed flap width in the central region is to be equal to 1 cm. The flap is turned on the feeding pedicle at an angle of 90°, laid over the wound surface on vestibular side of mandibular alveolar process and fixed with sutures on mucous membrane edge.

EFFECT: improved esthetic and functional results.
