Crestal incision using no. 15 blade on a bard parker no. 3. Two blind lateral vertical ostotomies at about 1.5 to 2 mm from the adjacent tooth roots to preserve subpapillary and root bone coverage. These cuts are to ensure the complete fracture of buccal plate while being attached to the overlying periosteum.

Crestal incision and 2 vertical releasing incisions will be made using a no.15 blade mounted on a Bard Parker no.3. Then, a full mucoperiosteal flap reflection to expose bone.
