Abstract:

During tooth extraction, the periodontal ligament, which is responsible for the formation of buccal bundle bone, is lost. Consequently, the blood supply to the bundle bone is discontinued, thereby affecting its nourishment and eventually causing its total or partial resorption. The retained root fragment preserves the periodontal ligament and supracrestal attachment of the tooth, thus avoiding buccal bone remodeling. The socket shield technique performed together with an immediate implant is a recently developed alternative method for the preservation and maintenance of tissues around a dental implant. In this method, a buccal root fragment is left in the socket instead of completely removing the tooth, and the implant is inserted palatal to it. This paper reviews the related articles of socket shield technique, which can help oral clinicians understand the technology more comprehensively.

Key words: socket shield technique, hard-tissue preservation, soft-tissue preservation
