Summary

Among the individuals who applied to the Department of Periodontology, Faculty of Dentistry, Health Sciences University between 2019 and 2021, patients with an unrestorable tooth in the maxillary esthetic region and required implant placement were included in this randomized clinical trial. Before implant surgery, patients were randomized into socket shield technique and guided bone regeneration groups. While the buccal gap was untreated in the socket shield group, a xenograft, and membrane were applied in the regeneration group. Peri-implant pocket depth, modified plaque index, modified bleeding index, keratinized mucosa width, and mucosal thickness were recorded at the permanent restoration and the postoperative first year. Horizontal bone level and vertical bone level were assessed with cone beam computed tomography images taken before the surgery and one year after prosthesis insertion. The pink esthetic score was evaluated with intraoral photographs taken before the surgical procedure and first-year follow-up.

Conditions

  • Immediate Implant Placement

Interventions

PROCEDURE

Socket shield technique

For the patients in the shield group, shields were prepared with the Root Membrane Kit. After the palatal part was removed, the buccal fragment was prepared at the crest level, and an internal bevel chamfer was formed on the fragment. Implants were placed 3-4 mm apical to the gingival margin of the adjacent teeth. Healing caps were placed, and the periphery of the caps was covered with an absorbable gelatin sponge.

PROCEDURE

Guided bone regeneration

For the patients in the regeneration group, teeth were extracted atraumatically, implants were placed 3-4 mm to the gingival margin, and the space between the implant and buccal bone was filled with anorganic bovine bone graft at the time of implant placement. The graft particles were covered by a pericardium membrane. The membrane was fixed to the bone with titanium pins.
