Contributions to the study of orthodontic mini-implants anchorage

Orthodontic implants, called mini-implants or temporary anchorage devices, have been designed to meet the needs of orthodontic biomechanics. Having the goal of providing resistance to unwanted tooth movements, anchorage is chosen according to the main factors that influence the quality of orthodontic care. Of these, local factors such as bone quality, space, thickness of the gum, etc. should be correlated with those watching the mini-implant design, geometric and dimensional factors that are taken into account for the stability of the mini-implant. This paper summarizes some of the results of the research aimed to analyze the main factors of stability of mini-implants used for orthodontic anchorage and how to measure it using the mini-implants (design shape and dimensions) and a special equipment for testing the tensile strenghth.
