Abstract Aim This case series aimed to evaluate the effectiveness of the autologous circular cortical lamina‐anchoring (CCA) technique for horizontal bone augmentation in the maxillary aesthetic region. Materials and methods A total of 25 patients with 28 implants underwent horizontal bone augmentation using CCA followed by implant placement and crown delivery. The primary outcome measures were alveolar ridge width (ARW) and buccal bone thickness (BBT), whereas the secondary outcome measures included marginal bone loss (MBL), mid‐facial mucosal margin loss (MML), clinical assessment of peri‐implant and aesthetic parameters, patient‐reported outcome measures (PROMs), and implant survival rates. Results All 25 patients with 28 implants completed the treatment, no dropouts occurred. After CCA, the mean ARW at 1, 2, and 4 mm below the alveolar crest significantly increased from 2.38 ± 0.48, 2.85 ± 0.51, and 3.21 ± 0.53 mm to 6.80 ± 0.48, 6.99 ± 0.50, and 8.08 ± 0.52 mm, respectively. At the 3‐year follow‐up, the mean BBT 0 , BBT 2 , and BBT 4 slightly decreased from 2.51 ± 0.26, 2.63 ± 0.31, and 2.75 ± 0.29 mm to 2.43 ± 0.27, 2.51 ± 0.30, and 2.64 ± 0.28 mm, respectively. Although the overall MBL was <0.15 mm, the results were statistically significant. The mean MML at the 3‐year follow‐up was 0.02 mm. All implant sites showed acceptable peri‐implant and aesthetic outcomes. Incisions healed without complications, and no significant differences in PROMs observed at any time point. The 3‐year follow‐up showed a 100% implant survival rate. Conclusion The autologous CCA technique is a useful method for increasing ARW and maintaining BBT in the maxillary aesthetic region.
