Cone-beam computed tomography revealed a distolingual RE with significant bone destruction around it, indicative of a through-and-through furcation defect. A treatment approach, known as vital root resection, which combined vital pulp therapy and surgical root resection, was implemented.

This manuscript describes a dual-layer flap preparation approach that utilizes an external coronally advanced flap (CAF) and an internal trapdoor periosteal flap (TPF) for EMS in the esthetic zone. The external CAF is a split-full-split-thickness flap that allows the gingival margin to be coronally advanced over the cementoenamel junction or prosthetic margin to mitigate any potential gingival recession due to flap retraction or to treat existing gingival recession. The internal TPF is the periosteal elevation of the partial-thickness tissue that remained following the elevation of the external CAF. The internal TPF employs vertical release(s) to obtain adequate access for periapical surgery. Sites treated with this approach healed with no complications, minimal patient discomfort, no facial recession or loss of papilla, and minimal soft tissue scarring.

The surgical techniques for vertical soft tissue augmentation and papilla augmentation at implant sites, their predictability, and outcomes have recently gained popularity among clinicians to meet patients' high esthetic demands. This study describes the application of the tunneled coronally advanced flap for vertical soft tissue reconstruction and papilla augmentation (verTCAF) for the treatment of peri-implant soft tissue dehiscences (PSTDs) characterized by papilla loss. Twelve patients with isolated PSTD in the anterior region were consecutively enrolled and treated with the verTCAF in combination with a connective tissue graft. This approach required a temporary phase prior to the surgery. The verTCAF involved a horizontal and vertical incision, with the opening of one surgical papilla one tooth more distal than the implant site. The anterior region, including the implant site and the interproximal soft tissue were tunneled. A connective tissue graft (CTG) was inserted and stabilized from the lateral opening, where the surgical papilla was raised. After the soft tissue augmentation and a new temporary phase of at least 3-4 months, the cases were finalized with new restorations. Patient- reported outcomes, and clinical and ultrasonographic measures were collected over 1 year to assess the results of the procedure. One year after the intervention, the subjects reported a significant improvement in the esthetics (93.92 visual analogue scale points at the last visit).
