The miniimplantes, for instance, have become the most discussed anchoring devices in Orthodontics. This work has the aim to establish ceilings twisting of resistance to fracture of miniimplantes. To that end, we used a sample of forty-five miniimplantes, and fifteen miniimplantes of 1.5 mm per 8 mm Brand Connection, fifteen miniimplantes of 1.3 mm per 9mm Brand Neodent and fifteen miniimplantes of 1.4 mm per 8mm Brand Sin. The sample was divided into three groups of fifteen, with five of miniimplantes each brand, according to the number of insertions and deletions made previously, that is, no, one and two insertions, all made by the same operator in jaws of pigs. The results showed that the average torque of miniimplantes rupture of the 45 tested was 12.2 N.cm, and that when the miniimplantes were subjected to an insertion and removal, this increased torque to break the mark in miniimplantes Sin (14 N.cm) and decreased in miniimplantes of brands Connection (10.8 N.cm) and Neodent (9.0 Nm). When the miniimplantes were subjected to two insertions and removals in jaws of pigs in all three national brands increased torque of a break for three brands: Connection (14.6 N.cm), Neodent (11.2 N.cm) and Sin (15.4 N.cm). It is therefore concluded that changes in mechanical behavior of miniimplantes in relation to resistance to fracture in three trademarks, when inserted and removed in mandibular bone pork once and that the torque of collapse rose were miniimplantes when inserted and removed twice.
