Objective: This study aims to collect data on implant survival, bone volume maintenance, and
complications associated with the socket shield technique. Background data: The socket shield
technique was introduced in 2010. Since then, several systematic reviews have been published,
showing good clinical outcomes. The behaviour of the buccal bone plate is so far not completely
understood. Methods: The study involved the placement of 23 implants using the socket shield
technique in 20 patients. AstraTech EV implants were used, and no bone substitutes or connective
tissue grafts were applied. Patients were monitored for 18 months, recording implant survival,
volumetric bone analysis on CBCT scans, interproximal bone levels, bone sounding, pink esthetic
scores, and complications. Prosthetic procedures were also described, including temporary and final
restorations. Results: A 95.7% cumulative 18-month implant survival rate was obtained using the
socket shield technique, with a significant but limited reduction in buccal bone thickness (BBT) after
implant placement. One implant did not integrate and two shields were partially exposed. The mean
pink esthetic score, 1 year after loading was 12.93 ± 1.22. Conclusion: The study suggests that the
socket shield technique can result in limited reduction of the buccal bone volume, with a high implant
survival rate. Re-entry studies are recommended to investigate the causes of bone resorption.
