  • To evaluate bone preservation and esthetic recovery between the socket-shield technique (SST) with different labial bone plate thicknesses and the conventional immediate implant technique (CIIT). Materials and Methods: Patients who underwent immediate implant placement in the anterior region were divided into three groups: the SST with a thickwall phenotype (> 1 mm; SSTA group), the SST with a thin-wall phenotype (< 1 mm; SSTB group), and the CIIT with a thickwall phenotype (> 1 mm; CIIT group). Radiologic images and clinical photos were collected before surgery, immediately postoperatively, and 6 months postoperatively. The labial bone width, labial bone width change (BWC), labial bone volume change (BVC), pink esthetic score (PES), and complication rate were evaluated among the three groups. Statistical analysis was performed using SPSS software. Results: A total of 60 patients (n = 20/group) were enrolled in this 6-month retrospective study. The BWC in the SSTA group (0.22 to 0.30 mm) and the SSTB group (0.18 to 0.33 mm) was less than that in the CIIT group (0.61 to 0.80 mm; P < .004). The SSTA group and the SSTB group had a lower BVC (24.08 vs 21.14 vs 54.81, respectively; P = .004) and greater PES (11.75 vs 11.65 vs 10.65, respectively; P = .009) than the CIIT group. No complications occurred among these patients. Conclusions: With the limitations of this study, it can be concluded that the SST is a reliable method for preserving bone and achieving satisfactory esthetic outcomes. The labial bone plate phenotype associated with the SST has minimal impact on both clinical and radiologic outcomes.
