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 BBT₀, BBT₂, and BBT₄ 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.

使用自体圆形皮质-粘合剂锚定技术进行上颌美学区域的水平嵴增量术：病例系列研究。

目的：本病例系列旨在评估自体圆形皮质薄层锚定（CCA）技术用于上颌美学区域水平骨增量的有效性：共有 25 名患者接受了 CCA 水平骨增量术，共植入 28 颗种植体，随后植入种植体并制作牙冠。主要结果指标是牙槽嵴宽度（ARW）和颊骨厚度（BBT），次要结果指标包括边缘骨损失（MBL）、中面部粘膜边缘损失（MML）、种植体周围和美学参数的临床评估、患者报告结果指标（PROMs）和种植体存活率：所有 25 名患者的 28 个种植体都完成了治疗，无一辍学。CCA 治疗后，牙槽嵴下 1、2 和 4 mm 处的平均 ARW 分别从 2.38 ± 0.48、2.85 ± 0.51 和 3.21 ± 0.53 mm 显著增加到 6.80 ± 0.48、6.99 ± 0.50 和 8.08 ± 0.52 mm。在 3 年的随访中，平均 BBT0、BBT2 和 BBT4 分别从 2.51 ± 0.26 毫米、2.63 ± 0.31 毫米和 2.75 ± 0.29 毫米轻微下降到 2.43 ± 0.27 毫米、2.51 ± 0.30 毫米和 2.64 ± 0.28 毫米。虽然总体 MBL 是结论：自体 CCA 技术是增加上颌美学区域 ARW 和保持 BBT 的有效方法。

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
