Measure
HEI Group
PAOO with horizontally extending incisions on both sides horizontally extending incisions (HEIs): 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.
VRI Group
PAOO with vertical releasing incisions on both sides Vertical releasing incisions (VRIs):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.

Timeframe: 12 months

Gingival scarring was evaluated at 12 months postoperatively through visual inspection. Participants were classified as scar-positive if any visible scar was present at the surgical site, including normotrophic scars (flat and white) and pathological scars (raised or irregular in shape). Each participant was counted once regardless of scar characteristics.

Timeframe: 1 day

The net weight of the bone graft material before surgery is recorded as W1. After surgery, the remaining bone graft material was collected, dried, and weighed by the same electronic scale as W2. The amount of bone graft material used during surgery was calculated as ΔW=W1-W2.
