Abstract

The current study aimed to assess the topographical and physical properties of a minimally invasive implant (MagiCore®: MC®, InnosBioSurg, IBS) and to evaluate its biological behavior compared to a gold standard implant (NobelParallel™: NB™, Nobel Biocare™). After surface characterization, the biological behavior assessment was conducted regarding human gingival fibroblasts (hGF) and osteoblast-like cells (MG63). Roughness values for NBTM were Ra = 1.28 µm and for MC® they were Ra = 2.02 µm. Alamar BlueTM assay LIVE/DEADTM staining results indicated equivalent biological development regarding both cell types for the two implants. Significant enhancement was found for hGF ALP activity in the presence of the two tested implants in a time-dependent manner from day 7 to day 14 (** p < 0.01). Alizarin red staining demonstrated significant calcium deposition enhancement when cells were interfaced with the NB™ compared to the MC® implant (** p < 0.05). Moreover, SEM and confocal imaging revealed good cell adhesion with a denser cellular layer on the MC® than the NB™ surface. The MC® cytocompatibility was ranked as equivalent to the gold standard implant despite the surface properties differences. These findings provide new insights about the minimally invasive implant’s biological behavior and its potential clinical implication in different implantology situations.

摘要

本研究旨在评估一种微创种植体(MagiCore®:MC®,InnosBioSurg,IBS)的表面形貌和物理特性,并与金标准种植体(NobelParallel™:NB™,Nobel Biocare™)相比,评估其生物学行为。在进行表面表征后,针对人牙龈成纤维细胞(hGF)和成骨样细胞(MG63)进行了生物学行为评估。NB™的粗糙度值为Ra = 1.28 µm,MC®的粗糙度值为Ra = 2.02 µm。Alamar BlueTM检测和LIVE/DEADTM染色结果表明,两种种植体对于两种细胞类型的生物学发育相当。在第7天到第14天,发现两种测试种植体存在时,hGF碱性磷酸酶(ALP)活性呈时间依赖性显著增强(**p < 0.01)。茜素红染色显示,与MC®种植体相比,细胞与NB™接触时钙沉积显著增强(**p < 0.05)。此外,扫描电子显微镜(SEM)和共聚焦成像显示,细胞在MC®表面的粘附良好,细胞层比NB™表面更致密。尽管表面特性存在差异,但MC®的细胞相容性与金标准种植体相当。这些发现为微创种植体的生物学行为及其在不同种植学情况下的潜在临床意义提供了新的见解。
