Abstract

MéTODOS PARA FABRICAR INSTRUMENTOS ENDODÈNTICOS. Instrumentos endodónticos com um gume desejado são conformados, pelo menos em parte, utilizando-se um processo de conformação a frio, O método de conformação do instrumento endodântico (32) inclui obter uma peça em bruto de fio ou arame de metal e um aparelho de conformação a rolos (30) que inclui matrizes (34a, 34b) que têm a impressão negativa de um gume. As matrizes (34a, 34b) são pressionadas de encontro à peça em bruto (32) com força suficiente para que as matrizes (34a, 34b) conformem, pelo menos parcialmente, o gume na peça em bruto (32) . Qualquer conformação desejada pode ser obtida para a peça em bruto (32) selecionando-se uma matriz com a impressão negativa correspondente. Técnicas de conformação a frio adequados para conformar instrumentos endodânticos incluem conformação a rolos, laminação plana, conformação radial, estiramento a frio e técnicas semelhantes. As limas podem ser afiadas ou modificadas de outro modo antes ou depois da conformação a frio com a utilização de técnicas tais como corte, esmerilhamento e fresagem química.
