“…Most commercial one-bottle and thus silane-coupling primers are supplied in a water-free solvent, upon which the silane is activated when clinically applied. To avoid having to use the rather caustic HF, even not used in certain countries, and to simplify ceramic-bonding procedures, combined etching and silanization has more recently been made possible with the introduction of Monobond Etch & Prime (Ivoclar Vivadent, Schaan, Liechtenstein) [2,3,8]. Previous research showed that silane-containing so-called 'universal' adhesives did not have enough silane-coupling effect [7,9].…”

Objective: Hydrofluoric-acid etching followed by silanization is a routine clinical protocol for durable bonding to glass ceramics. Simplifying ceramic-bonding procedures, new technological developments involve the inclusion of a silane coupling agent in a self-adhesive composite cement. To investigate the effectiveness of the incorporated silane coupling agent, shear bond strength (SB) to ceramic and dentin, contact angle of water (CA), transmission electron microscopy (TEM), X-ray diffraction (XRD) and 29 Si nuclear magnetic resonance (NMR) assessments were correlatively conducted.Materials and Methods: SB to glass ceramic was measured without ('immediate') and with ('aged') 50K thermocycles upon application of (1) the silane-containing self-adhesive composite cement Panavia SA Cement Universal ('SAU'), being light-cured: 'SAU_light', (2) 'SAU_chem': chemically cured SAU, (3) 'SAP_light': light-cured Panavia SA Cement Plus ('SAP'), and (4) 'SAP_CP': SAP light-cured after separate silanization using Clearfil Ceramic Primer Plus ('CP'). CA was also measured on glass ceramic. The cement pastes before and upon mixing were characterized using 29 Si NMR. SB of SAU or SAP onto dentin was measured. Finally, the cement-dentin interface was characterized by TEM and XRD.Results: The immediate and aged SB to glass ceramic of SAU did not significantly differ from those of SAP_CP, while they were significantly higher than those of SAP. CA of SAU did not significantly differ from that of SAP_CP, but it was significantly higher than CA of SAP. 29 Si NMR revealed siloxane bonds after mixture. SB of SAU and SAP to dentin did not show any significant difference. SEM, TEM and XRD confirmed tight and chemical interaction, respectively.Significance: Incorporating silane in a 10-MDP-based self-adhesive composite cement combined efficient silane-coupling ability at the ceramic surface with effective bonding ability at dentin. HighlightsThe clinical procedure to adhesively lute ceramic restorations is complex, by which a simplified application procedure is desirable.Silane-coupling monomers degrade in water; hydrolysis is avoided when the silane-coupling monomer is added to the cement's hydrophobic paste. Once mixed, the silane-coupling monomer hydrolyses to chemically interact with the ceramic surface.The novel silane-containing self-adhesive cement combined efficient silane-coupling ability onto glass ceramics with adequate self-adhesiveness onto dentin.

“…Em 1998, o AF foi reconhecido como um produto químico bastante perigoso em função de sua toxicidade, corrosividade e reatividade (LITOVITZ et al, 1998). A alta toxicidade é decorrente do potencial do AF em gerar necrose de tecidos moles e ossos ao longo do tempo de exposição prolongado (SCHERER et al, 2018), portanto, a aplicação do AF deve ser restrita a peça cerâmica, para evitar danos à mucosa bucal do paciente. A grande vantagem do uso do AF na cerâmica é que sua aplicação é muito simples, o que significa que métodos sofisticados de condicionamento e limpeza da superfície cerâmica são desnecessários (ÖZCAN; ALLAHBEICKARAGHI; DÜNDAR, 2012), e ainda, o condicionamento de AF seguido de uma aplicação de agente de acoplamento de silano continua sendo o protocolo de ligação padrão ouro (PRADO et al, 2018).…”

“…Essas cerâmicas são sensíveis ao ácido fluorídrico (AF), que causa alterações em suas superfícies, promovendo uma melhor interação com os cimentos resinosos. O AF possui alta toxicidade, portanto, deve ser aplicado apenas na peça cerâmica, pois caso entre em contato com a mucosa pode causar necrose tecidual e óssea dependendo do tempo de exposição e concentração do ácido (SCHERER et al, 2018).…”

O preparo das superfícies cerâmicas é umas das etapas fundamentais para uma adesão duradoura e satisfatória no substrato dentário, garantindo o sucesso do tratamento. A escolha dos produtos corretos confere à prótese maior estabilidade após cimentação, evitando: infiltrações, cáries secundárias e deslocamento da peça cerâmica. Nos últimos tempos, vários protocolos para preparo das superfícies cerâmicas estão sendo usados em função da ampla oferta de produtos no mercado. Diante da diversidade de produtos disponíveis, esta revisão de literatura tem como objetivo mostrar, por meio de artigos, qual o protocolo mais seguro a ser seguido para a cimentação de cerâmicas de dissilicato de lítio. Realizou-se uma revisão de literatura baseada em artigos científicos publicados nas seguintes bases de dados: Scientific Electronic Library Online (SciELO), Medline: Pubmed e Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), sendo a amostra final composta por vinte e seis estudos. Verificou-se que, para uma adesão adequada das cerâmicas de dissilicato de lítio ao substrato dentário, deve-se seguir o passo a passo do preparo da superfície, sendo a aplicação do ácido fluorídrico, seguido de silano e adesivo a opção mais segura. O modo simplificado de preparo, usando sistemas autocondicionantes pode ser promissor, porém mais estudos são necessários para comprovar sua eficácia. Palavras-chave: Ácido Fluorídrico. Adesivos. Dissilicato de Lítio. Abstract The ceramic surfaces preparation is one of the fundamental steps for a lasting and satisfactory adhesion to the dental substrate, guaranteeing the success of the treatment. The correct products choice gives the prosthesis greater stability after cementation, avoiding: infiltrations, secondary caries and e ceramic piece displacement. In recent times, several protocols for preparing ceramic surfaces have been used due to the wide range of products in the market. Due to the diversity of products available, this literature review aims to show, through articles, which is the safest protocol to be followed for the cementation of lithium disilicate ceramics. A review was carried out based on scientific articles published in the databases: Scientific Electronic Library Online (SciELO), Medline: Pubmed and Latin American and Caribbean Literature in Health Sciences (Lilacs), with the final sample comprising twenty-six studies. It was found that, for an adequate lithium disilicate ceramics adhesion to the dental substrate, one must follow the step by step of the surface preparation, with the hydrofluoric acid (HF) application, followed by silane and adhesive which is the safest option. The simplified preparation method, using self-etching systems, can be promising, however, more studies are needed to prove its effectiveness. Keywords: Hydrofluoric Acid. Adhesives.

“…Surface etching using hydrofluoric acid has mainly been performed on glass ceramics. This approach removes the silica-containing glassy matrix and exposes the crystalline phase [ 31 , 32 ]. However, zirconia is resistant to conventional etching techniques because it is a silica-free ceramic and consists of a high-temperature crystal phase [ 11 , 33 , 34 , 35 ].…”

The aim of this work was to evaluate the effects of application time of an acid mixture solution on the surface roughness, phase transformation, and biaxial flexural strength of 3Y-TZP after sintering or air abrasion. For the biaxial flexural strength measurement, 220 3Y-TZP disk-shaped specimens were prepared after as-sintering or air abrasion. The etching solution comprised a mixture of hydrofluoric acid, sulfuric acid, hydrogen peroxide, methyl alcohol, and purified water. The samples were divided into 11 subgroups according to the etching times (Control, 1, 2, 3, 5, 8, 10, 12, 15, 20, and 30 min). The results showed that acid treatment on both as-sintered and air-abraded 3Y-TZP surfaces increased the surface roughness. However, it had no significant effects on the monoclinic phase or flexural strength of as-sintered zirconia. The monoclinic phase and flexural strength of air-abraded zirconia increased sharply after air abrasion; however, they gradually decreased after acid treatment, to a similar level to the case of the untreated surface. Surface treatment with acid mixture increased the roughness, but the lack of increase of monoclinic phase is thought to be because the loose monoclinic particles remaining on the surface were removed through the etching process.
