What type of cement is preferred for cementation of ceramic veneers?

The preferred type of cement for the cementation of ceramic veneers is composite resin. This is primarily due to the strong bonding capabilities that composite resin offers. When bonding ceramic materials, achieving a high degree of adhesion is critical because it directly affects the longevity and success of the veneer. Composite resins contain materials that create a chemical bond with both the ceramic and the underlying tooth structure, providing superior strength and durability.

Additionally, composite resin cements usually possess aesthetic qualities that align well with the natural appearance of the ceramic veneers, ensuring a seamless look. They are less soluble in oral fluids, making them more resistant to breakdown compared to other types of cements, which is particularly important in the oral environment where moisture levels can vary.

In contrast, glass ionomer cement and resin-modified glass ionomer cement, while useful in certain dental applications, do not provide the same level of mechanical strength or commitment to aesthetic requirements needed for ceramic veneers. Zinc phosphate cement, on the other hand, may not bond as effectively to the ceramics and can also be associated with higher solubility and less favorable aesthetic qualities. Therefore, composite resin stands out as the best choice for this specific application.
