Therefore, resin-based luting composites are the material of choice for the adhesive luting of ceramic restorations14). Composite cements have compositions and characteristics similar to conventional restorative composites and consist of inorganic fillers embedded in an organic matrix (for example: Bis-GMA, TEGDMA, UDMA). Composite cements can be classified according to their initiation mode as autopolymerizing (chemically activated), photoactivated, or dual-activated materials14). Photoactivated composites offer wide varieties of shades, consistencies, and compositions. Clinical application is simplified through long handling times before and rapid hardening after exposure to light. Shade, thickness, and transmission coefficient of the bonded ceramic restoration and the composite itself influence the conversion rate of the photo-activated material and limit its application to thin silica-based ceramics. Dual-activated composites offer extended working times and controlled polymerization14), although chemical activators ensure a high degree of polymerization. Most dual-activated resin cements still require photopolymerization and demonstrated inferior hardness when light polymerization was omitted. Autopolymerizing resin cements have fixed setting times and are generally indicated for resin bonding metal-based or opaque, high-strength ceramic restorations.

Resin cements with reduced filler contents offer improved flow, increased surface wettability, and optimal positioning of the restoration15). However, filler-containing composite cements revealed higher bond strengths than resins without fillers16) and hybrid composites showed better results than microfilled composites. Highly filled resin cements may improve abrasion resistance at the marginal area, reduce polymerization shrinkage, and facilitate removal of excess cement14). Wear and substance loss of composite cements after final insertion have been extensively studied in laboratory and clinical investigations that demonstrated a correlation of marginal gap width and depth of wear17). However, the effect of wear resistance of resin cements on the clinical longterm success of bonded restorations remains to be determined. Other properties of these materials need to be investigated before they can be recommended for bonding of ceramic high viscosity materials may be pulled out of the luting gap during cleaning restorations without reservation.

Adhesive cementation may not be required for final insertion of high-strength all-ceramic restorations with proper mechanical retention. However, some clinical situations and restorative treatment options mandate resin bonding and adequate ceramic-surface conditioning. Preferred treatments for glass-infiltrated aluminum-oxide ceramic are either airborne particle abrasion with Al2O3 (50 to 110 μm at 2.5 bar) and use of a phosphate-modified resin cement (Panavia 21) or tribochemical surface treatment (Rocatec System) in combination with conventional Bis-GMA resin cement. The small number of long-term in vitro studies on the bond strength to densely-sintered aluminum-oxide ceramic does not allow for clinical recommendations. The few available studies on resin bonding to zirconium oxide ceramics suggest the use of resin cements that contain special adhesive monomers. Compared with silica-based ceramics, the number of in vitro studies on the resin bond to high-strength zirconia ceramics is small. The rapidly increasing popularity of all-ceramic systems requires further investigation of resin-zirconia ceramic bonding.
