CUTANDO, A.; GOMEZ-MORENO, G.  e  ARANA, C.. Bioactive surfaces in implantology: a new perspective. Avances en Periodoncia [online]. 2007, vol.19, suppl.1, pp.43-50. ISSN 2340-3209.

At present, after years of investigation in implantology, in which there have been realized a lot of works, with different types of surfaces of implants, smooth and rough, in an attempt of improving, both in the time and in the quality, the osteointegration, one has concluded that the implants of rough surface with an interval of rugosity between 1.0-2.0 nm, are those who seem to give a better bone response and better clinical results, but from an exclusively mechanical point of view. Nowadays the investigations centre on the development of named bioactive surfaces, which are capable to react with the bone around the implant, since it happens when the implant is redressed in carbonate cálcico or in fluorine. But we know that inside the bone metabolism, there are another important molecules: the melatonin and the hormone of the growth between others, which must be born in mind at the time of speaking of osteointegration. There is realized a brief description of the physiology of both molecules and his application is valued to the concept of bioactive surface in implantology.

Palavras-chave : Implant; bioactive surface; melatonin; hormone of the growth.
