Objectives: The optimization of titanium surfaces is essential to accelerate the process of osseointegration and to enable rehabilitative treatments in a short period of time. The objective of the present study was to evaluate comparatively two surface treatments of the nanometric type in dental mini-implants, being a commercial and another experimental, regarding the morphological and chemical characterization. Material and methods: Two groups were evaluated: G1 – titanium mini-implants with surface treatment Ossean® (Intra-Lock) and G2 – titanium mini-implants with experimental surface treatment. After the experimental treatment, by means of an attack with phosphoric acid followed by alkaline treatment, the implants were evaluated by scanning electron microscopy (SEM), in two different ways, SE (secondary electron) that analyzes the topographic changes in the samples and BSE (back-scattered electrons) that analyzes the composition changes or fluctuations in the sample surface. The chemical composition was analyzed by an X-ray dispersive energy spectroscopy (EDX) system. Results: SEM images confirmed differences in G1 and G2 surfaces, with the presence of nanometric pores in G2, whereas EDX analysis demonstrated the incorporation of elements characteristic of the stimulation of bone neoformation. Conclusions: The experimental surface treatment, as a chemical process, besides being simple, was effective in the formation of a rough surface and with bioactive capacity.
