The success of the restorative dental ceramic cementation is partly related to the correct indication of a surface treatment of the ceramic substrate. Several types of treatment have been proposed in the literature, among which is hydrofluoric acid etching and silanization. However, acid etching can reduce the strength of the ceramic depending on the extent of crystalline phase removal, and this type of acid require great care in handling because its high toxicity. With the possibility to optimize the effectiveness of silane by heating them at the time of evaporation, there is a new possibility in mind in dentistry, to suppress the use of hydrofluoric acid as a conditioner for ceramic surface treatment in the dental office and with it the their risks to human health because of its high toxicity. Thus, the purpose of this review is to address the thermal treatment of the silane as a way to improve the adhesive cementation of ceramic restorations.
