Optimizing the design of preactivated titanium T-loop springs with Loop software

ATMA (Ormco Corp, Glendora, Calif) T-loop spring (TTLS), preactivated with a gable bend distal to the loop, holds promise for producing controlled tipping of the canines and translation of the posterior segment. However, there is currently no consensus as to where the preactivated gable bend or the loop should be placed, what the height of the loop should be, or how the interbracket distance changes the moments produced. Using the Loop software program (dHal, Athens, Greece), we systematically modified a .017 x .025-in TTLS (10 x 6 mm) that was preactivated with a 45 degrees gable bend distal to the loop, and simulated the effects. As the gable bend was moved posteriorly, the moment increased at the posterior bracket more than it decreased at the anterior bracket. As the loop was brought closer to the anterior bracket, the posterior moment decreased at the same rate that it increased anteriorly. As the loop was increased in size, the moments increased both posteriorly and anteriorly. As the interbracket distance increased, the posterior moment decreased, and the anterior moment remained constant. We concluded that the size of the loop should be slightly increased, to 10 x 7 mm, and it should be placed 2 mm from the anterior bracket, with a preactivation bend of 45 degrees, 4 to 5 mm from the posterior bracket (after 4 mm of activation).

O pensamento político em Eurípides / Euripides” political thought

No sempre reconhecido realismo euripidiano se inclui um envolvimento político. É notável o elogio a Atenas, seja a seu passado ilustre, seja a seu papel no mundo grego. Entretanto a guerra a que Atenas se atira e que faz enfraquecer a Grécia é condenada, pois a defesa de Atenas, concretizada na defesa de seu regime político, a democracia, não inclui a defesa do imperialismo ateniense. Assim, acima de Eurípides patriota se ergue o Eurípides humanista, preocupado com as responsabilidades do ser humano, não apenas do cidadão. Eurípides’ acknowledge realism includes a political involvement. The eulogy of Athens is remarkable both regarding her illustrious past and her role in the greek world. The war in which Athens is engaged and which weakens Greece, however, is condemned, for Athens’ defense, made real in the defense of her political regime, democracy, does not include the defense of Athenian imperialism. Thus, Euripides the patriot is excelled by Euripides the humanist, who is more concerned with the responsibilities of the human being, than with those of the citizen’s.
