“…However, most adhesive monomers that promote binding to precious metals do not have the hydrophilic group, but have a group containing sulfur atoms in place. Nowadays, an adhesive monomer is defined as a polymerizable monomer whose structure is constituted by three parts: a polymerizable functional group (PG), an adhesion promoting group (AG) and a connecting group [22], the latter being An organic group connecting the PG and AG groups [23].…”

“…Thus, a combined application of a dithio-octonoate monomer and a phosphonic acid monomer provided effective solidex bonding of metals and alloys of precious and non-precious metals [41]. The intensity of the exoelectron emission activity on the sandblast metal surfaces decreases with time in the air [22,23], resulting in a decrease in bond strength. However, when the sandblast metal surfaces were coated with a metal primer containing a dithiooctonoate monomer and a phosphonic acid monomer, there was no significant degradation of the bond strength, even after storage of 2 months in the air at 50º C [42].…”

A descriptive bibliographic review of the evidence provided in indexed articles and other bibliographic sources, such as books, theses and others, has been made. These were analyzed and after checking whether or not they met the inclusion/exclusion criteria of this work, finally were 27 articles of bibliographic review published in a hairpin that goes from 2007 to 2016. IntroductionThe use of metals in dentistry has great therapeutic advantages in many fields of dentistry, such as orthodontics, prostheses, conservative dentistry since its origins and more recently implantology [2]. Likewise, metals can be used on numerous and varied substrates: enamel, dentin, ceramics, resins or other metals [1]. Examples of adhesion of enamel or dentin to metals, orthodontic bands and brackets, or Maryland type adhesive bridges. It may be necessary to attach a metal to ceramics in the case of a metal crown, which by aesthetics will be covered or another metal (such as a cast post) to the metal of the crown and / or ceramics thereof, or even when it is free of metal [4].The first and foremost objective of dental adhesives is the long-lasting attachment to their substrates or adhesives, whether hard dental tissues or a wide range of materials (some new and others already contaminated when already in the mouth). The adhesive system, already discovered by Bouncoure and Bowen in the 1960s, has meant an improvement in speed, efficiency and convenience by simplifying the joining steps of two bodies of disparate origin and nature and reducing the time in the clinician's working time. The current trend in the development of dental adhesive systems follows the line of self-etch adhesives, multipurpose primers or adhesives that give a strong and durable adhesion indiscriminately to a multitude of adherents that coexist in the oral environment, ranging from tejdios (Enamel and dentin), precious metals (noble), alloys of precious metals and alloys of non-precious metals to dental porcelain, ceramics based on aluminum oxide (alumina) and zirconium-based ceramics [6,7].Do not overlook the many detractors of self-etch adhesives. On the one hand self-etching adhesives are easy to use and less prone to cause postoperative sensitivity. Although on the other hand, AbstractThe use of metals in dentistry presupposes the need for mechanisms of retention or adhesion of the same to different substrates; Such as enamel, dentin, ceramics, old resins and other metals [1].Throughout history these mechanisms have been changing and evolving, from the purely mechanical retention to the present mechanisms of adhesion [2,3]. It is in the decade of the 70 when they begin to develop adhesion materials. Prior to this, retention was basically mechanical, having also evolved from macromechanical retention systems to micromechanical retention systems [3]. It is at the end of the 70 when the first generation of adhesives appears; These monomers were 4-META (4-methacryloyloxyethyl trimellitate anhydride) and 10-MDP (10-methacryloyloxydecyl dihydrogen phosphate). Thes...

“…On the latter recommendation, Gu et al reported that the mechanical properties of hydroxyapatite (HA)-zirconia (ZrO2)-filled CGIC were superior to those of HA-CGICs 12) . In the same vein, Mashaverinia et al reported that the mechanical properties of CGICs incorporated with nanoceramic particles (nano-hydroxyapatite or fluoroapatite) were markedly improved when compared to CGICs 13,14) . At this juncture, it must be highlighted that the mechanical properties and bond strength to tooth substrate of RMGICs for luting or filling purposes are inferior to those of resin cements or resin composites [5][6][7] .…”

Mechanical properties of a resin-modified glass ionomer cement for luting: effect of adding spherical silica filler

et al. 2010

This study investigated the effects of spherical silica filler (SSF) on the workability and mechanical properties of resin-modified glass ionomer cements for luting (RMGICL). Varying powder/liquid ratios (P/L=2.0, 2.2, 2.4, and 2.6) of a commercially available glass ionomer cement (Fuji Lute, GC Corp.) were mixed with SSF at different weight percentages (5, 7.5, and 10%). On film thickness, statistically significant effects of SSF addition were noted at 2.5 minutes after mixing started, notably at P/L=2.4 and 2.6 when 7.5 and 10 wt% of SSF were added. The same result was also obtained for consistency evaluation. On mechanical and bonding strengths to the tooth substrate, no statistically significant differences were observed among all the SSF weight percentages within each P/L ratio. SSF-added RMGICL at a higher powder/liquid ratio exhibited increased mechanical and bonding strengths when compared to a control without SSF addition, but nonetheless maintained the film thickness with no further increase.
