The objective of this study was to compare acellular dermal matrix graft (ADM) combination with coronally advanced flap (CAF) on complete defect coverage, aesthetics and patient satisfaction with CAF alone for multiple recessions with gingival thickness (GT) <0.8 mm.
Forty-eight Miller Class I multiple recessions ≥3 mm were divided into test (CAF + ADM) and control (CAF) groups. At baseline and 12 months, recession height (RH), keratinized tissue height (KT), GT, mean and complete defect coverage were evaluated. Patient satisfaction, root coverage aesthetic score (RES) and the correlation between GT and defect coverage were also assessed.
Baseline RH in CAF + ADM and CAF groups was 3.25 ± 0.34 mm and 3.21 ± 0.26 mm, respectively. Mean and complete defect coverage were 94.84% and 83.33% in test group, 74.99% and 50.00% in control group, respectively. Inter-group differences were found to be statistically significant for RH reduction, attachment gain, KT and GT increase, mean defect coverage and RES in favour of test group (p < 0.05). There was a significant positive correlation between GT and mean defect coverage (p < 0.05).
Coronally advanced flap in association with ADM can be proposed as a valid approach for the treatment of multiple recessions with thin tissue biotype.
本研究旨在比较脱细胞真皮基质移植物（ADM）联合冠向推进瓣（CAF）与单独 CAF 在牙龈厚度（GT）<0.8mm 的多个退缩中完全覆盖缺损、美学效果和患者满意度。
48 例 Miller Ⅰ类多个≥3mm 的退缩分为试验组（CAF+ADM）和对照组（CAF）。在基线和 12 个月时，评估了退缩高度（RH）、角化组织高度（KT）、GT、平均和完全缺损覆盖。还评估了患者满意度、根覆盖美学评分（RES）以及 GT 与缺损覆盖之间的相关性。
CAF+ADM 和 CAF 组的基线 RH 分别为 3.25±0.34mm 和 3.21±0.26mm。试验组的平均和完全缺损覆盖分别为 94.84%和 83.33%，对照组分别为 74.99%和 50.00%。组间差异在 RH 降低、附着增加、KT 和 GT 增加、平均缺损覆盖和 RES 方面具有统计学意义（p<0.05）。GT 与平均缺损覆盖之间存在显著正相关（p<0.05）。
与 ADM 联合应用的 CAF 可作为治疗薄组织生物型多个退缩的有效方法。
