To evaluate efficacy of platelet-rich fibrin (PRF) or connective tissue graft (CTG) in papilla reconstruction (PR) with the semilunar incision (SI) technique.
The analysis consisted of 55 sites (27 CTG and 28 PRF) from 20 patients who underwent PR with either PRF or CTG placed in the maxillary anterior region with SI technique. Baseline (BL) and follow-up (T , first month, T , third month, T , sixth month) clinical data including periodontal evaluations (gingival index (GI), plaque index (PI), pocket depth (PD), keratinized tissue width (KTW), gingival recession), papilla-associated recordings (alveolar crest-interdental contact point [AC-IC], alveolar crest-papilla tip [AC-PT], papilla tip-interdental contact point [PT-IC], papilla height loss [PHL], interdental tissue stroke [ITS] and papilla presence index [PPI]) and patient satisfaction were analyzed.
CTG provided better PR outcomes. GI, PI, and PD showed a slight increase at T and then, turned to their BL levels. The other periodontal parameters showed significant improvement after both treatment modalities. No inter-group difference was found except for KTW, which was in favor of CTG.
Based on the results, CTG is recommended over PRF in PR treatment due to its superior outcomes with less recurrence risk.
Connective tissue graft provides superior results than platelet-rich fibrin in papilla reconstruction with the semilunar incision technique.
评估富血小板纤维蛋白（PRF）或结缔组织移植物（CTG）在新月形切口（SI）技术辅助的牙乳头重建（PR）中的疗效。
该分析包括 20 名患者的 55 个部位（27 个 CTG 和 28 个 PRF），这些患者在前上颌区域采用 SI 技术进行 PR，其中分别使用 PRF 或 CTG。基线（BL）和随访（T1，第 1 个月，T2，第 3 个月，T3，第 6 个月）的临床数据包括牙周评估（牙龈指数（GI）、菌斑指数（PI）、牙周袋深度（PD）、角化组织宽度（KTW）、牙龈退缩）、牙乳头相关记录（牙槽嵴-牙间隙接触点[AC-IC]、牙槽嵴-牙乳头顶点[AC-PT]、牙乳头顶点-牙间隙接触点[PT-IC]、牙乳头高度损失[PHL]、牙间组织突度[ITS]和牙乳头存在指数[PPI]）和患者满意度。
CTG 提供了更好的 PR 结果。GI、PI 和 PD 在 T1 时略有增加，然后恢复到 BL 水平。两种治疗方式后其他牙周参数均有显著改善。除 KTW 外，两组间无差异，CTG 更有利。
基于这些结果，由于 CTG 复发风险较低，在 PR 治疗中推荐使用 CTG 而不是 PRF。
在 SI 技术辅助的牙乳头重建中，与 PRF 相比，结缔组织移植物提供了更好的结果。
