The surface of dental implants has undergone multiple modifications across the timeline to enhance osseointegration, thereby enhancing the success of dental implants. This study compared the surface roughness, wettability and topography of sandblasted acid-etched, and oxidized titanium dental implants. Three commercially available implants-namely, SLA, SLActive, and TiUnite-were evaluated for surface roughness in terms of Ra, Rq, and Rz; wettability in terms of contact angle (CA); and topography using scanning electron microscopy (SEM). Roughness and wettability values were compared between the three surfaces by ANOVA and pairwise comparison by Tukey's HSD post hoc testing using SPSS Software. A p value of < 0.01 was considered to be statistically significant. The TiUnite surface exhibited the highest roughness values (Ra = 1.91 ± 0.006 μm, Rq = 2.99 ± 0.005 μm, Rz = 8.37 ± 0.003 μm) followed by the SLA and SLActive surfaces. The contact angles of the SLA, SLActive, and TiUnite dental implants were 98.44 ± 0.52°, 9 ± 0.03°, and 94.39 ± 0.08°, respectively. These data demonstrated statistically significant differences between the three surfaces (p < 0.01). There were no distinct differences in SEM features between the SLA and SLActive surfaces. However, the TiUnite surface exhibited a distinctly porous morphology. Oxidized dental implants differ from sandblasted acid-etched implants in terms of roughness, wettability, and surface topography.
牙科种植体的表面经过多次修改，以增强骨整合，从而提高牙科种植体的成功率。本研究比较了喷砂酸蚀和氧化钛牙科种植体的表面粗糙度、润湿性和形貌。评估了三种市售种植体，即 SLA、SLActive 和 TiUnite，以评估 Ra、Rq 和 Rz 方面的表面粗糙度；接触角（CA）方面的润湿性；以及使用扫描电子显微镜（SEM）的形貌。使用 SPSS 软件通过方差分析和 Tukey 的 HSD 事后检验进行两两比较，比较三种表面之间的粗糙度和润湿性值。p 值 < 0.01 被认为具有统计学意义。TiUnite 表面表现出最高的粗糙度值（Ra = 1.91 ± 0.006 μm，Rq = 2.99 ± 0.005 μm，Rz = 8.37 ± 0.003 μm），其次是 SLA 和 SLActive 表面。SLA、SLActive 和 TiUnite 牙科种植体的接触角分别为 98.44 ± 0.52°、9 ± 0.03°和 94.39 ± 0.08°。这些数据表明三种表面之间存在统计学显著差异（p < 0.01）。SLA 和 SLActive 表面之间的 SEM 特征没有明显差异。然而，TiUnite 表面表现出明显的多孔形貌。氧化钛种植体在粗糙度、润湿性和表面形貌方面与喷砂酸蚀种植体不同。
