Abstract

Background: Soft tissue integration (STI) around dental implant abutments is a prerequisite to prevent bacterial invasion and achieve successful dental implant rehabilitation. However, peri-implant STI is a major challenge after dental abutment placement due to alterations in the immune microenvironment upon surgical dental implant installation.

Methods: Based on known immunomodulatory effects of zinc, we herein deposited zinc/chitosan/gelatin (Zn/CS/Gel) coatings onto titanium substrates to study their effect on macrophages. First, we exposed macrophages to cell culture media containing different zinc ion (Zn²⁺) concentrations. Next, we explored the immunomodulatory effect of Zn/CS/Gel coatings prepared via facile electrophoretic deposition (EPD).

Results: We found that Zn²⁺ effectively altered the secretome by reducing the secretion of pro-inflammatory and enhancing pro-regenerative cytokine secretion, particularly at a Zn²⁺ supplementation of approximately 37.5 μM. Zn/CS/Gel coatings released Zn²⁺ in a concentration range which effectively stimulated pro-regenerative macrophage polarization as demonstrated by M2 macrophage polarization. Additionally, the impact of these Zn²⁺-exposed macrophages on gingival fibroblasts incubated in conditioned medium showed stimulated adhesion, proliferation, and collagen secretion.

Conclusion: Our promising results suggest that controlled release of Zn²⁺ from Zn/CS/Gel coatings could be applied to immunomodulate peri-implant STI, and to enhance dental implant survival.

开发具有免疫调节作用的含锌壳聚糖/明胶涂层，用于牙科植入物周围的软组织密封。

背景：牙科种植基台周围的软组织整合（STI）是防止细菌入侵和实现成功牙科种植康复的先决条件。然而，由于手术安装牙科种植体时免疫微环境的改变，种植体周围的 STI 是牙科基台安装后的一大挑战：方法：基于锌的已知免疫调节作用，我们在钛基底上沉积了锌/壳聚糖/明胶（Zn/CS/Gel）涂层，以研究其对巨噬细胞的影响。首先，我们将巨噬细胞置于含有不同浓度锌离子（Zn2+）的细胞培养基中。接着，我们探讨了通过简易电泳沉积（EPD）制备的锌/CS/凝胶涂层的免疫调节作用：结果：我们发现 Zn2+ 有效地改变了分泌组，减少了促炎症细胞因子的分泌，增强了促再生细胞因子的分泌，尤其是在 Zn2+ 补充量约为 37.5 μM 时。Zn/CS/Gel 涂层释放的 Zn2+ 浓度范围能有效刺激巨噬细胞的促再生极化，这一点已通过 M2 巨噬细胞极化得到证实。此外，这些暴露于 Zn2+ 的巨噬细胞对在条件培养基中培养的牙龈成纤维细胞的影响显示，它们的粘附、增殖和胶原分泌都受到了刺激：我们的研究结果表明，Zn/CS/凝胶涂层中 Zn2+ 的可控释放可用于种植体周围 STI 的免疫调节，并提高种植体的存活率。
