Resumo
Foram realizadas 35 restaurações de amálgama com três tipos de ligas: uma convencional L3 (Velvalloy) e duas outras de alto teor de cobre - uma defase dispersa L1 (Aristaloy 21) e outra ternária L2 (Novaloy). As restaurações foram submetidas a momentos distintos de execução do polimento: polimento mediato e polimento imediato. Avaliou-se clinicamente as restaurações de amálgama, no exame básico, aos seis, doze e dezoito meses, pelo método direto de GUNNAR RYGE. Através da análise dos resultados, pode-se verificar e concluir: a) nas restaurações examinadas não ocorreram recidivas de cárie; b) as margens das restaurações sofreram alterações em função do tempo; e c) o tipo de polimento exerceu influência no comportamento das restaurações.

Abstract
Thirty-five amalgam restorations were made, with three alloy types: a conventional alloy L3 (Velvalloy), and two high copper alloy 12 (Novaloy). The restorations were suhmitted to different moments of polishing: mediate polishing and immediate polishing. The amalgam restorations were clinically evaluated in the hasic exam, in the course of six, twelve, and eighteen months, through the GUNNAR RYGE direct method. From the analysis of the results, it could be found and concluded: a) ln the restorations examined, caries recurrences, and fracture did not occur; b) the restoration margins suffered alterations with time and, c) the polishing type had some influence on the restoration behavior.
