Abstract
Aim : To assess the surface topography and chemical composition of three brands of as-received mini-implants (SIN(r), Morelli(r), and Conexao(r)). 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(r), Morelli(r), and Conexao(r) 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(r)presented also N and O in their composition. Conclusions: In conclusion, the miniimplants Morelli(r), SIN(r) and Conexao(r) 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(r)mini-implants presented N and O. As far as surface topography is concerned, there are no differences among the three brands of mini-implants.

TADs are used when dental anchorage is insufficient or a large amount of dental movement is required[1]. These devices are widely used in Orthodontics offering excellent results and solving anchorage problems that could not be addressed previously[2] by overcoming the active versus reactive forces generated during tooth movement[3]
Mini-implants from SIN®, Morelli® and Conexao® had Translational research is an important component of orthodontic research since it can translate information from the laboratory to enhance the outcomes of patients’ treatments[3]

TADs are used when dental anchorage is insufficient or a large amount of dental movement is required[1] These devices are widely used in Orthodontics offering excellent results and solving anchorage problems that could not be addressed previously[2] by overcoming the active versus reactive forces generated during tooth movement[3]. The optimal use of TAD should have some requirements such as small size, placement without drilling, stability to withstand immediate and long term loading, easy removal and comfort for the patient[4]. All these features, especially the small dimensions of mini-implants, require a strong, high-grade titanium alloy. The design of miniimplants should feature a head to engage elastic bands or sprains, a smooth transmucosal neck, an endossous self tapping body and a special groove in their tip to be used for cutting or tapping the bone during insertion, which is called lead angle[1]
