At the enormously interesting course in April 2017 on the socket-shield technique we looked at different cases of implant surgery using this innovative, cutting-edge technique.

All dentists know that bone collapse occurs after tooth extraction, i.e. that the bone reduces in depth and width, meaning that if we want to insert an implant in that area it is essential to preserve the bone anatomy.

When implants are made immediately a tooth is extracted, it is extremely important to be able to maintain the width of the remaining bone space, or socket. With this technique, a radicular fragment is left in the external part of the socket, thereby acting as a protective shield when fitting the implant.

This radicular lamina is obtained by sectioning the root using a diamond bur, leaving a single radicular lamina in the socket together with its periodontal ligament, which keeps it fixed to the bone. The fragment must be fixed in place and not move.

Long implants are used, anchored to the apical area, placing growth factors between the implant and the radicular fragment. Bone is therefore produced in the gap between the implant and the radicular remnant. This is known as the socket-shield technique.

This technique appears to give very good results and several cases are now being published. We will keep a close watch on its evolution.
