LIMA, José H. Cavalcanti et al. Functional evaluation of implants by bone mineralization in vitrot. Rev. Bras. Odontol. [online]. 2015, vol.72, n.1-2, pp. 92-95. ISSN 1984-3747.

Improvements in dental implants structure is the result of development of different types of geometrically intelligent surfaces, provided by the emergence of companies interested in innovation of these materials, however, there is still a need for studies to define the type of ideal surface. This work addresses an unprecedented discussion regarding implant surface evaluation methods, able to show the potential of certain areas to induce bone mineralization in vitro. From the use of mesenchymal progenitor cells, which have the capacity to respond to stimuli surface, comparative tests were performed between the topography implants with and without nano-roughness and the type of functional interaction between pre-osteoblasts seeded directly into these implants. Different characteristics of coating cells and mineralization niches on different surfaces were found.
