Classification of resin cement with incurred risks, according to polymerization mode.

Resin Cement	Indications	Contra-Indications	Risk
Light-cured [104]	Thin and translucent veneers	Thick and more opaque veneers	Incomplete photo-polymerization at the thick parts of the veneer
Dual-cured [103]	Thick and more opaque veneers	Thin HT veneers	Discoloration, a prejudice in thin veneers cases
Base paste of the dual-cured system [103]	Optional with some dual-cured resin cement	Thick and more opaque veneers	Sub-optimal cure of the resin cement
