“…This mechanism accelerates the polymerization process of the cement contacting the primer. 31 This system ensures that adhesive failures between the tooth and cement do not occur in the autopolymerization mode. 24 Therefore, in the present study, resin cement containing 10-MDP was selected for its high binding values to zirconia, [22][23][24] its long-term color stability, 28,32 and the advantages of the special polymerization mechanism.…”

For patient satisfaction, restoration of missing teeth and tooth tissues with biocompatible materials that are resistant to occlusal forces also require attention to esthetics. 1,2 Esthetic restorations should be able to mimic the natural color depth of teeth, luminous transmittance, and anatomic structures. 2 In recent years, monolithic zirconia crowns have been developed. 3 Monolithic zirconias, which are produced with computer-aided design and computer-aided manufacturing (CAD-CAM) systems, consist of atoms interpenetrating without any organic binder and also have high dimensional stability. 3,4 Because they have a natural appearance, they do not need to be veneered with feldspathic ceramics, and natural tooth color can be obtained by characterization. 5 Therefore, chipping of the veneer porcelain is not a factor. 3,6,7 Monolithic zirconias have high biocompatibility and a nonporous structure, 8 and their abrasion resistance is close to that of natural teeth. 9 They cause significantly lower abrasion in antagonist teeth than veneered zirconia crowns. 10,11 In addition, they can be used in situations with insufficient interocclusal clearance, even at an occlusal thickness of 0.5 mm because of their high resistance to fracture. 12

“…To overcome this, some systems include catalysts both in the adhesive and the core material. In our laboratory, such type of resin core system was named "Touch and Cure" 10) . In a conventional type of "Touch and Cure'' system, polymerization starts when the adhesive comes in contact with the core material.…”

“…An alternative curing approach is being referred to as “touch cure” or “contact cure” (Kawano et al 2015; Aung et al 2019), by which polymerization starts at the cement-tooth interface. The commercial composite cement Panavia V5 (Kuraray Noritake) employs touch cure and contains a proprietary nontertiary amine accelerator, which accelerates curing when it contacts the cement (technical information, Kuraray Noritake Panavia V5).…”

Touch-Cure Polymerization at the Composite Cement-Dentin Interface

et al. 2021

Ceramic restorations are often adhesively luted onto the tooth prep. The so-called touch-cure concept was developed to yield optimum polymerization of composite cement at the restoration-cement-tooth interface for immediate bond stabilization. Although this touch cure is theorized to initiate polymerization at the interface when the accelerator in the primer makes contact with the cement, this process has not yet been proven. This study aimed to elucidate the mechanism of touch cure by measuring the degree of conversion (DC) of composite cement applied with or without an accelerator-containing tooth primer (TP) versus an accelerator-free primer using real-time Fourier-transform infrared spectroscopy (RT-FTIR) and attenuated total reflection (ATR)–FTIR. Interfacial bond strength was measured in shear mode, the accelerator composition confirmed by X-ray fluorescence analysis (XRF), and the interfacial interaction of TP and composite cement with dentin investigated by X-ray diffraction (XRD), focused-ion-beam scanning electron microscopy (FIB-SEM) with 3-dimensional interface reconstruction, and transmission electron microscopy (TEM). RT/ATR-FTIR revealed the significantly highest DC when the composite cement was applied with the accelerator-containing primer. XRF disclosed a vanadium compound as a novel chemical accelerator within TP, instead of a classic chemical curing initiator system, to set off touch cure as soon the cement contacts the previously applied primer. Although the TP contains the acidic functional monomer 10-MDP for adhesion to tooth tissue, touch cure using the accelerator-containing TP combined the fastest/highest DC with the highest bond strength. FIB-SEM and TEM confirmed the tight interfacial interaction at dentin with submicron hybridization along with stable 10-MDP also Ca-salt nanolayering.
