RESUMO
Este trabalho avalia a fricção superficial dos bráquetes autoligados e bráquetes convencionais, suas vantagens e desvantagens. Alguns estudos avaliaram fatores como: os materiais dos fios e dos bráquetes, as condições da superfície dos fios e do encaixe do bráquete, a secção do fio, o torque na interface fio-bráquete, a angulação dos bráquetes, o tipo e a força da ligadura, a salina e as funções bucais. Estes fatores influenciam na fricção tanto dos bráquetes autoligados como dos bráquetes convencionais, porém todos os bráquetes autoligados mostraram valores de fricção inferiores aos dos bráquetes convencionais, tanto no atrito estático como cinético.
ABSTRACT
The present paper compares the friction surface of self-ligated brackets and conventional brackets, their advantages and disadvantages, based in studies wich evaluates such factors as the materials of wires and brackets, the surface condition of the wires and the brackets fit, the cable section, the torque on the bracket-wire interface, the angle of the brackets and strength of their ligations, the saline and oral functions. These factors influence the friction of both self-ligated brackets and conventional brackets, but all self-bonded brackets showed lower friction values compared to those of conventional brackets in both (static and kinetic) frictions.
