Brief summary

23 implants with socket shield were followed for 18 months. buccal bone thickness and survival rates registered.

Detailed description

Aims: This study aims to collect data on implant survival, bone volume maintenance, and complications associated with the socket shield technique. Materials & 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.
