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.
