Modified Labial Pedicle Papilla Flap (mLPPF) With or Without De-epithelialized Gingival Graft (dGG) for Peri-implant Papilla Reconstruction

Standard papilla-preserving incision without additional flap modification or connective tissue grafting. This group serves as the control, receiving only routine surgical access for implant site management.

Surgical reconstruction of the peri-implant papilla using the modified labial pedicle papilla flap technique. The flap is mobilized and sutured without adjunctive grafting procedures.

Surgical reconstruction of the peri-implant papilla combining the modified labial pedicle papilla flap with placement of a de-epithelialized gingival graft (dGG) at the papillary region to enhance soft tissue volume and stability.
