Comparación de la fuerza adhesivas en cerámicas reforzadas con disilicato de litio cementadas previa colocación de silano de dos frascos, un frasco y adhesivo universal con silano

Background: In modern dentistry macro-retentive preparations are less used and it has become more adhesive, so vitreous restorations have become the material of choice, due to their long-term mechanical and optical properties. Resinous cement and vitreous restorations are dissimilar materials and silane is needed which is the most widely used coupling agent to generate adhesion in vitreous restorations. Currently there are several presentations: two-part silane, single bottle and those that are included in a universal adhesive, which some commercial brands acclaim its effectiveness without the need to acquire pure silane. Currently there is no consensus on which the most suitable type of presentation is. Objective: To generate a criterion of the factors that affect the longevity of restorations to the clinician related to the selection of silane by its presentation. Materials and Method: This is a review the literature of the factors that affect the hydrolysis of silane and its condition according to its type of presentation and storage. A search was performed in the PUBMED, EBSCO, NCBI and Research Gate databases. Conclusion: Currently there is no comparative study of all the presentations, however, various authors show that there are no significant differences between the silane from one bottle and that from two bottles during the first year of use and universal adhesives have less hydrolytic stability to long term.
