Abstract:

In Implant Dentistry, the buccal alveolar ridge contour in the esthetic area has been confirmed as one of the key elements to obtain a high esthetic outcome. However, tooth extraction is always followed by the resorption of labial alveolar bone, especially in the most coronal 2 ~ 3 mm area, which can then cause dimensional changes in the remnant alveolar bone and severe gingival margin recession damaging the pink aesthetic outcome of peri-implant tissue. Therefore, immediate implant placement has been a significant challenging treatment modality for the clinician. The recently popularized socket shield technique involves intentional retention of a section of the remnant root at the time of immediate implant placement, thereby preserving the buccal bone from resorption. The objective of this systematic review was to assess the literature available on the socket shield technique and summarize its theoretical basis, indications and surgical essentials, as well as the long-term clinical outcomes and management of complications.
