Aim: To quantify the numbers of Biofilm formed over the surface of the different material used in the rehabilitation about implants.
Materials and methods: Four commonly used materials were investigated: Titanium, Zirconium, Aleation of Cromon-Niquel and termocurated acrylic resin, from each one, 8 pieces of known dimensions were needed, four of them to make an aerobious microorganisms crop, and the rest for anaerobious, with a total number of thirty-two units of materials. The samples were taken from a patient without any tooth, in the upper and in the lower side, for a long time and without systemic relevance history, all this was done with the purpose of not having modifying factors of the dental plaque. Every piece of the sample was undergone to the lab technique of 96-well microtiter plate and later to the espectofotometer for the bacterial counting.
Results: More quantity of biofilm is formed in aerobious conditions than in anaerobious. The Titanium allows the production of biofilm in both situations and the thermo acrilic is which allows the less production.
Conclusion: It should reinforce hygiene techniques, consider the material of the structures that will be placed in the mouth, and maintenance checks in patients having implant restorations.
The professional must emphazise the mentioned concepts, because not for offering first quality material, a patient is safe of suffering an alteracion in the periimplanting tissues, on the contrary, these have affinity with the bacterian community known as biofilm.
