Resumo
The objective of this study was to identify the best torque of insertion and removal of
mini-implants with a twin screw design (compact and self-drilling) into artificial bones with density
and trabecular thickness, similar to anterior, middle and posterior regions of the jaws. Observation
of the mini-implants surface using electron microscopy was performed before and after the tests.
The torque values obtained during the insertion and removal was measured by digital torque
wrench. The analyzed results led to the conclusion that the insertion and removal torques were
larger with increase in bone density and cortical thickness. The design of the threads of the miniimplants
influenced the insertion torque. Threads with smaller pitch increased the value of insertion
torque. The anterior bone drilling installation reduces the insertion torque independent of bone
density. Torque increased mainly by increasing the bone density and not necessarily with increased
cortical thickness suggesting that the bone density of the trabecular bone must be considered in
designing the installation of mini-implants.
