简要总结
Anterior maxilla (Esthetic zone) is very challenging area because of thin buccal plate of bone. After tooth extraction physiological process occur causing alteration of bone and soft tissue so, delayed placement of implant lead to loss of bone height and width. Immediate placement of implant is become essential to preserve the bone and soft tissue from loss.
Socket shield technique is a recent technique which is by sectioning the root and extraction of palatal part and leaving buccal part of the root with its attachment of periodontal ligament and vascularization still intact then placing implant in palatal socket. This technique allow preservation of buccal plate of bone and soft tissue with minimum loss allowing better result in esthetic zone.
