Abstract

Objective: To assess the impact of mechanical decontamination using rotary brushes on the surface topography, elemental composition, roughness, and wettability of titanium implant surfaces.

Methods: Four commercially available rotary brushes were used: Labrida BioClean Brush® (LB), i-Brush1 (IB), NiTiBrush Nano (NiTiB), and Peri-implantitis Brush (PIB). Seventy-five titanium discs with sandblasted, large-grit, acid-etched (SLA) surfaces were randomly assigned to five groups (n = 15): LB, IB, NiTiB, PIB, and a control group. Each disc was treated for 60 seconds with the respective rotary brush according to the manufacturer's instructions. Surface morphology was analysed using Scanning Electron Microscopy (SEM), surface elemental composition with Energy Dispersive X-ray (EDX), surface roughness via optical profilometry, and wettability with a droplet shape analyser.

Results: SEI analysis revealed morphological changes, including scratches, flattening, and loose titanium particles in the IB, PIB, and NiTiB groups, whereas the LB group preserved the original surface morphology. SEM-EDX analysis showed that LB, PIB, and NiTiB groups closely match the control elemental composition. However, IB groups showed significantly different composition. Surface roughness values in the IB, PIB, and NiTiB groups differed significantly from the control (p < 0.05), whereas the LB group had comparable roughness values (p > 0.05). Contact angle measurements indicated enhanced wettability in IB, PIB, and NiTiB groups (p < 0.05), while the LB group exhibited values comparable to the control (p > 0.05).

Significance: Mechanical decontamination of implant surfaces utilising rotary brushes can alter implant surface properties.

机械仪器对钛种植体表面性能的影响。

目的：评价旋转刷机械去污对钛种植体表面形貌、元素组成、粗糙度和润湿性的影响。方法：使用四种市售旋转刷：Labrida BioClean Brush®（LB）， i-Brush1 (IB), NiTiBrush Nano （NiTiB）和种植体周围刷（PIB）。75个表面喷砂、大粒度、酸蚀（SLA）的钛盘随机分为5组（n = 15）：LB、IB、NiTiB、PIB和对照组。根据制造商的说明，用相应的旋转刷处理每个圆盘60 秒。用扫描电子显微镜（SEM）分析表面形貌，用能量色散x射线（EDX）分析表面元素组成，用光学轮廓仪分析表面粗糙度，用液滴形状分析仪分析润湿性。结果：SEI分析显示IB组、PIB组和NiTiB组的表面形貌发生了划痕、变平、钛颗粒疏松等变化，而LB组的表面形貌保持了原始形态。SEM-EDX分析表明，LB、PIB和NiTiB组与对照元素组成密切匹配。然而，IB组的组成有显著差异。IB组、PIB组和NiTiB组的表面粗糙度值与对照组有显著差异（p  0.05）。接触角测量显示IB、PIB和NiTiB组的润湿性增强（p  0.05）。意义：使用旋转刷对种植体表面进行机械净化可以改变种植体表面特性。
