What is socket Shield Technique?

A technique used in immediate implant cases, where instead of completely removing the tooth, a root fragment is left in the socket, as the implant is inserted.

The socket shield technique is essential in preserving tissues, and has been used with immediate implant placement. Without socket shielding after tooth extraction, the alveolar bone undergoes a remodeling process, which leads to horizontal and vertical bone loss. Socket shielding has been described to retain the original dimension of the bone after extraction. It has also been suggested that resorption of the bundle bone can be avoided by leaving a root segment (socket shielding technique) in place, because the biological integrity of the periodontium ( bundle bone) remains untouched.

Therefore, the theory is that by leaving a root fragment in place, you will predictably maintain this  bone.
