Abstract
Aim: To assess the surface topography and chemical composition of three brands of as-received
mini-implants (SIN®, Morelli®, and Conexao®). Methods: Twelve mini-implants of each brand
were analyzed by scanning electron microscopy and energy dispersive X-ray (EDX). Results:
There was no significant differences among SIN®, Morelli®, and Conexao® mini-implants comparing
their surface topography by visualization of SEM micrographs and analysis of scores. The EDX
analysis showed statistically significant difference among them for the amount of Ti, Al and V. Miniimplants
SIN® presented also N and O in their composition. Conclusions: In conclusion, the miniimplants
Morelli®, SIN® and Conexao® presented Ti as main component of the alloy. Remaining
components, such as Al and V, were also observed in all the analyzed brands, with differences
among them. Only SIN® mini-implants presented N and O. As far as surface topography is
concerned, there are no differences among the three brands of mini-implants.
