I have really become a believer in Adhese Universal and Esthetic Variolink (Dual) for my quadrant cementation technique.  It is about tissue management, isolation, a simplistic adhesive system to avoiding post cementation sensitivity, and easy resin cement cleanup.   The Adhese Universal/Esthetic Variolink-Dual Cure Ivoclar system will do that for you and there is excellent literature to support the quality and predictability of this Ivoclar system.
