The socket-shield technique and immediate implant placement

Abstract

Healing of extraction socket leads to the dimensional changes which will affect the placement of the implant and its emergence profile. Atraumatic extraction, socket preservation technique, and immediate implant placement decrease the alveolar bone resorption by maintaining the postextraction socket. Hürzeler et al. introduced socket-shield technique by keeping a buccal fragment of the tooth to prevent the buccal cortical bone from resorption. This case report represents a 40-year-old male patient with grossly decayed maxillary left lateral incisor indicated for extraction replaced with an immediate implant. While examining cone-beam computed tomography, thin buccal cortical plate was noticed which may get fracture during extraction. Socket-shield technique was designed for implant placement to protect buccal bone and to get the proper esthetic form. Two millimeters buccal fragment of the tooth was kept attached and the implant was placed in contact with tooth fragment. Three-month follow-up shows proper healing, and healthy peri-implant tissue shows that socket-shield technique with immediate implant placement will be a good alternative to preserve buccal cortical plate and implant placement, especially in the esthetic area.

Socket‐shield technique for implant placement to stabilize the facial gingival and osseous architecture: A systematic review

“…Detailed analysis of the included studies is presented in Table as clinical and animal studies on the SST and their outcome. Of the included studies, 11 were case reports, 6 case series, 1 clinical randomized control trial, 1 technical report and 2 animal randomized control trials …”

“…Hurzeler et al 5 used heterologous graft material between the root portion and the implant to fill the jumping distance of 2 mm or more. Dayakar et al 22 in their study placed a bone graft between the implant surface and the socket wall as the lingual jumping distance was more than 1 mm. It is recommended that a graft in between the implant and shield does not serve much of a role and should be restricted to cases where the jumping distance is more than 1 mm.…”
