horizontal extending incision
a papilla preserving incision will be made on the labial side of the front teeth with a thin alveolar bone or dehiscence and/or fenestration. Then horizontally extending incisions will be added to each side of the initial incision, extending one to two teeth beyond the defected area, before a full-thickness flap is lifted.
vertical releasing incision
a papilla preserving incision will be made on the labial side of the front teeth with a thin alveolar bone or dehiscence and/or fenestration. Vertical releasing incisions will be made on each side of the initial incision before a full-thickness flap is lifted. The incision formed an oblique trapezoidal flap with a wider base.
