Abstract
The aim of this paper is to analyze the influence
of the nature of the orthodontic archwires on the friction
coefficient and wear rate against materials used commonly as
brackets (Ti–6Al–4V and 316L Stainless Steel). The mate-
rials selected as orthodontic archwires were ASI304 stainless
steel, NiTi, Ti, TiMo and NiTiCu. The array archwire’s
materials selected presented very similar roughness but
different hardness. Materials were chosen from lower and
higher hardness degrees than that of the brackets. Wear tests
were carried out at in artificial saliva at 37
C. Results show a
linear relationship between the hardness of the materials and
the friction coefficients. The material that showed lower
wear rate was the ASI304 stainless steel. To prevent wear,
the wire and the brackets have high hardness values and in
the same order of magnitude.
