A Novel Surgical Procedure for Peri-implant Papilla Reconstruction in the Aesthetic Region: Modified Labial Pedicle Papilla Flap Technique With De-epithelialized Gingival Graft
In Brief
A clinical study evaluating Papilla-preserving incision (Control), Modified Labial Pedicle Papilla Flap (mLPPF), and 1 other intervention for Peri-Implant Papilla Deficiency. Completed, enrolled 80 participants across 1 site.
Detailed Summary
This randomized controlled clinical trial aims to evaluate the effectiveness of two surgical techniques for peri-implant papilla reconstruction in single-tooth implants in the maxillary anterior and premolar regions. A total of 80 cases with papilla deficiency were allocated into three groups: papilla-preserving incisions only (Control), modified labial pedicle papilla flap (mLPPF), and mLPPF combined with a de-epithelialized gingival graft (mLPPF+dGG). Clinical outcomes including papilla fill (Jemt scores), papilla height, and crestal mucosa thickness were assessed at baseline, immediately after surgery, two weeks postoperatively, and six months after final restoration. The primary goal is to determine whether combining connective tissue grafting with flap surgery provides superior and more stable papilla reconstruction compared with papilla preserving flap-only approaches.
Study Details
Timeline
Interventions
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.
