Abstract
A realização do tratamento de superfície em cerâmica pura visa criar microirregularidades internas para aumentar a resistência mecânica da interface de união com o cimento resinoso. O objetivo desse trabalho de revisão de literatura foi determinar o melhor tratamento de superfície para os sistemas IPS Empress, IPS Empress 2, In-Ceram Alumina, In-Ceram Zirconia e Procera All-Ceram. Foi possível observar que as cerâmicas reforçadas por leucita ou dissilicato de lítio são facilmente condicionadas com ácido hidrofluorídrico seguido por silanização. A associação de silicatização, silanização e cimentação com cimentos resinosos à base de monômero fosfatado proporciona altos valores de resistência de união para cerâmicas à base de óxido de alumina ou óxido de alumina e zircônio e aluminizada densamente sinterizada.
Keywords

Resumo
Surface conditioning methods of all-ceramic systems are used to create micromechanical interlocking to enhance the bond strength of resin cement to the ceramic surface. The aim of this literature review was to recognize the most reliable surface conditioning method for durable bond of resin cement to IPS Empress, IPS Empress 2, In-Ceram Alumina, In-Ceram Zirconia, and Procera All-Ceram. It was found that leucite- and lithium disilicate-based ceramics are easily etched by hydrofluoridric acid followed by silanization. The association of silica coating, silanization, and resins containing phosphate monomers showed high bond strength values for glass-infiltrated alumina, glass-infiltrated zirconia, and densely-sintered high-purity aluminum-oxide ceramics.
