Criteria for updating the crystalline silica gel

It is reasonable to assume that unless a specific indication for a given luting agent exists, the least technique-sensitive material should be used.

The type of restoration being fabricated also has an important role in the selection of a luting agent, with the requirements of bonded restorations being very different from those of cast restorations.Feldspathic Ceramic Due to their exceptional esthetic properties, clinicians often choose silica-based ceramics, such as feldspathic porcelain and glass ceramic for veneering the metal frameworks or high-strength ceramic copings of their all-ceramic restorations.Although the feldspathic ceramic is brittle with low flexural strength by itself, modern adhesive cementation with composite increases the fracture resistance of the ceramic.The clinical efficacy of these cements has been confirmed in the scientific literature.RMGI cements are the most frequently used cements in North America for the cementation of well-fitting porcelain-fused-to-metal crowns, full-cast crowns, and high-strength (eg, zirconia, alumina) ceramic restorations.
