Abstract
"INSTRUMENTO PARA ALARGAMENTO MECâNICO DOS CANAIS DE RAIZ, E SEQuêNCIA DE INSTRUMENTOS COMPREENDENDO PELO MENOS UM DE TAL INSTRUMENTO". A invenção refere-se a um instrumento para alargar um canal de raiz, em particular, na zona apical alojando em sua parte proximal um manípulo para uso manual ou na cabeça de uma peça manual de contra-ângulo do dentista, a parte distal da dita lâmina sendo uma ponta aguda de tipo conhecido. A invenção é caracterizada pelo fato de que a parte de corte ativa da lâmina possui, a partir da ponta aguda e continuamente, duas seções cónicas tal que, ao lado da ponta aguda, cada seção cónica possui uma relação de afunilamento maior que a parte distal menor adjacente à mesma. A invenção é útil para alargar canais de raiz com seq³ências de instrumento impedindo o enfraquecimento da raiz e enchimento de fluxo de material na extremidade de canal.
