The socket-shield technique: a step-by-step protocol after 12 years of experience
Staehler, Philip / Abraha, Sophia M. / Bastos, Joel / Zuhr, Otto / Hürzeler, Markus
The socket-shield technique, first published in 2010, has gained worldwide scientific and clinical acceptance. To address possible complications with this innovative approach in esthetic implant dentistry, we provide a comprehensive step-by-step protocol incorporating what we have learnt in the past decade. After initial decoronation of the tooth, the implant bed is prepared through the root of the tooth to be extracted. Following extraction of the palatal root fragments, the shield is prepared according to either a mechanical or biologic 'locking' principle. The mechanical 'locking' comprises a direct contact between the implant and the shield, whereas the biologic approach facilitates ankylosis of the shield, preventing its coronal displacement. The coronal part of the shield is brought into a concave shape, ending up 0.5 mm coronal to the buccal bone. The implant is consequently inserted, and an individualized healing cap fabricated. When performed according to the underlying biologic and mechanical principles, the socket-shield technique can provide highly esthetic and predictable outcomes.
