Local flap Buccal flap - A sharp probe is used to locate the edge of the bone -Excise soft tissue margin leaving 2-3 mm. rim
Buccal flap (cont.) -Vertical incision with a board base on buccal mucoperiosteal flap -The periosteum lining the inner surface of the flap is cut parallel to and close to its base, allowing the flap to be stretch
Buccal flap (cont.) -The palatal margin is slightly undermined and the wound close with mattress sutures.
Advantage - Broad base providing good blood supply -No raw surface left behind - No rotation Disadvantage -Reduction of buccal vestibule
Palatal flap -Excise an elongated mucoperiosteal palatal flap, which follow the course of the greater palatine artery. It should be for long enough for its free end to be rotated to cover the defect.
Palatal flap (cont.) -Care of the greater palatine artery not to cut or damage it -The flap is sutured across the defect using mattress sutures
