简要总结

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.

详细描述

This study aimed to compare the non-grafted socket shield technique with simultaneously guided bone regeneration in immediate implant placement in terms of clinical, esthetic, and radiographic parameters. Within the scope, immediate implant placement was applied to randomized groups (socket shield technique and guided bone regeneration). Immediate implant placement was performed following shield preparation in the shield group, and guided bone regeneration was applied in the regeneration group. A temporary non-functional immediate prosthesis was inserted at the same visit. After four months, permanent restorations were applied. Clinical, radiographic, and esthetic parameters were compared between two groups at baseline and first-year follow-up.
