To assess the impact of mechanical decontamination using rotary brushes on the surface topography, elemental composition, roughness, and wettability of titanium implant surfaces.
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.
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).
Mechanical decontamination of implant surfaces utilising rotary brushes can alter implant surface properties.
评估使用旋转刷进行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。
使用四种市售旋转刷：Labrida BioClean Brush®（LB）、i-Brush1（IB）、NiTiBrush Nano（NiTiB）和种植体周围炎刷（PIB）。将75个具有喷砂、大颗粒、酸蚀（SLA）表面的钛盘随机分为五组（n = 15）：LB组、IB组、NiTiB组、PIB组和对照组。根据制造商的说明，用相应的旋转刷对每个盘进行60秒的处理。使用扫描电子显微镜（SEM）分析表面形态，用能量色散X射线（EDX）分析表面元素组成，通过光学轮廓仪分析表面粗糙度，并用液滴形状分析仪分析润湿性。
扫描电镜分析显示，IB组、PIB组和NiTiB组出现了形态变化，包括划痕、表面平整和钛颗粒松散，而LB组保留了原始表面形态。扫描电镜-能谱分析表明，LB组、PIB组和NiTiB组的元素组成与对照组密切匹配。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），而LB组具有可比的粗糙度值（p > 0.05）。接触角测量表明，IB组、PIB组和NiTiB组的润湿性增强（p < 0.05），而LB组的值与对照组相当（p > 0.05）。
利用旋转刷对种植体表面进行机械去污会改变种植体表面性能。
