The aim of this case series was to evaluate the clinical performance of a new volume-stable collagen matrix (VCMX) in combination with the modified coronally advanced tunnel technique (MCAT) for the treatment of gingival recessions. Thirteen patients with a total of 33 maxillary RT1 single and multiple gingival recessions were included in the study. Probing pocket depth (PPD), recession width (RECW), recession depth (REC), height of keratinized tissue (HKT), and gingival thickness (GT) were assessed at baseline and at the 12-month follow-up. Postoperative healing was uneventful in all cases without any complications. At 12 months, mean root coverage (MRC) was 92.88%, with complete root coverage (CRC) in 87.88% of treated sites. The present findings suggest that VCMX in combination with MCAT results in predictable coverage of maxillary RT1 gingival recessions. Further studies with larger sample sizes and control groups are needed to support these preliminary outcomes.
本病例系列的目的是评估新型体积稳定型胶原基质（VCMX）联合改良冠向推进隧道技术（MCAT）治疗牙龈退缩的临床效果。研究纳入了 13 名患者共 33 个上颌 RT1 单发性和多发性牙龈退缩。在基线和 12 个月随访时评估探诊袋深度（PPD）、退缩宽度（RECW）、退缩深度（REC）、角化组织高度（HKT）和牙龈厚度（GT）。所有病例术后愈合均顺利，无任何并发症。12 个月时，平均根覆盖（MRC）为 92.88%，87.88%的治疗部位达到完全根覆盖（CRC）。本研究结果表明，VCMX 联合 MCAT 可实现对上颌 RT1 牙龈退缩的可预测性覆盖。需要进一步开展更大样本量和对照组的研究来支持这些初步结果。
