Abstrakt: Purpose: Establishment of titanium surface treatment and comparison of surface roughness and osteogenic potential of commercially pure titanium. Materials and Methods: Twenty commercially pure grade 2 titanium disks of similar design and dimensions were divided into two groups. Smooth samples were assigned as control group (Group S). The second group (Group SLA) samples were sand-blasted and etched with different acids. Scanning Electron Microscopy (SEM) at ×500 was performed to observe the surface morphology. The surface roughness of samples was evaluated with surface profilometer. To evaluate the effect of surface treatment, samples from each group underwent cell culture study using human osteosarcoma osteoblast cell lines (HOS). SEM of one sample from each group was performed at ×500 to observe the cell morphology and cell attachment. Results: Sand-blasted and acid-etched (SLA) surface was rougher in comparison to the smooth surface. SEM result of sand-blasted and acid-etched surface (Group SLA) showed that cell sheets were able to adhere inside the valleys suggesting excellent attachment osseointegration to rough surface. Conclusion: This approach to develop sand-blasted and acid-etched surface was successful in uniform distribution of human osteosarcoma osteoblast cell lines (HOS) suggesting excellent osseointegration.
