Numerous techniques have been reported in the literature for the reconstruction of gingival recession defects. The purpose of this case series was to evaluate clinically and radiographically the efficacy of sticky bone with i-PRF-coated collagen membrane in the treatment of gingival recession.
Sixteen patients exhibiting isolated Miller's Class I or II recession in the maxillary esthetic zone were treated using sticky bone (i-PRF + freeze-dried bone allograft) with i-PRF-coated collagen membrane using the coronally advanced flap. Clinical parameters including probing depth (PD), width of keratinized gingiva (WKG), gingival thickness (GT), and recession depth (RD) were recorded at baseline and 6 months post-surgery. The radiographic (ST-CBCT) measurements computed were labial plate thickness (OT1, OT3, and OT5) and GT (GT1, GT3, and GT5) at baseline and 6 months post-treatment. Twelve out of sixteen treated cases achieved complete root coverage. An increase in GT was observed in all the cases.
Within the limitations of this case series, sticky bone with i-PRF-coated collagen membrane showed promising results in the treatment of isolated maxillary Miller's Class I or II gingival recession and serves as an altered approach for root coverage procedure. However, histological analysis and larger sample size are needed to establish definitive proof of soft and hard tissue regeneration.
文献中报道了许多用于重建牙龈退缩缺陷的技术。本病例系列的目的是评估粘性骨联合 i-PRF 涂层胶原膜在治疗牙龈退缩中的临床和放射学疗效。
16 名上颌美学区存在孤立性 Miller Ⅰ类或Ⅱ类牙龈退缩的患者接受了粘性骨（i-PRF+冻干骨移植物）联合 i-PRF 涂层胶原膜的冠向推进瓣治疗。在基线和术后 6 个月记录临床参数，包括探诊深度（PD）、角化龈宽度（WKG）、牙龈厚度（GT）和退缩深度（RD）。在基线和治疗后 6 个月时计算的放射学（ST-CBCT）测量值包括唇板厚度（OT1、OT3 和 OT5）和 GT（GT1、GT3 和 GT5）。16 例治疗病例中有 12 例达到了完全根覆盖。所有病例的 GT 均增加。
在本病例系列的限制范围内，粘性骨联合 i-PRF 涂层胶原膜在治疗孤立性上颌 Miller Ⅰ类或Ⅱ类牙龈退缩方面显示出良好的效果，可作为根覆盖手术的一种替代方法。然而，需要进行组织学分析和更大的样本量研究，以确定软组织和硬组织再生的明确证据。
