“…Based on this hypothesis, various kinds of surface modification of Ti metal and its alloys have been proposed for inducing apatite formation and/or bone bonding capability. Ion implantation [ 4 - 6 ], hydrothermal treatments [ 7 - 12 ], electrochemical reactions [ 13 - 22 ] are some examples of these surface modifications. However, they require special equipment and are not readily applicable to large-scale devices of complicated shape or comprised of porous material.…”

To reveal general principles for obtaining bone-bonding bioactive metallic titanium, Ti metal was heat-treated after exposure to a solution with different pH. The material formed an apatite layer at its surface in simulated body fluid when heat-treated after exposure to a strong acid or alkali solution, because it formed a positively charged titanium oxide and negatively charged sodium titanate film on its surface, respectively. Such treated these Ti metals tightly bonded to living bone. Porous Ti metal heat-treated after exposure to an acidic solution exhibited not only osteoconductive, but also osteoinductive behavior. Porous Ti metal exposed to an alkaline solution also exhibits osteoconductivity as well as osteoinductivity, if it was subsequently subjected to acid and heat treatments. These acid and heat treatments were not effective for most Ti-based alloys. However, even those alloys exhibited apatite formation when they were subjected to acid and heat treatment after a NaOH treatment, since the alloying elements were removed from the surface by the latter. The NaOH and heat treatments were also not effective for Ti-Zr-Nb-Ta alloys. These alloys displayed apatite formation when subjected to CaCl2 treatment after NaOH treatment, forming Ca-deficient calcium titanate at their surfaces after subsequent heat and hot water treatments. The bioactive Ti metal subjected to NaOH and heat treatments has been clinically used as an artificial hip joint material in Japan since 2007. A porous Ti metal subjected to NaOH, HCl and heat treatments has successfully undergone clinical trials as a spinal fusion device.

“…Efficacy of metal primers in the adhesion of resin compounds to precious and non-precious metals and alloys [40][41][42] Experimental metal primers containing a dithio-octanoate monomer (10 MDDT or 6 MHDT) and a phosphonic acid monomer (6-MHPA or 6 MHPP) were prepared to evaluate their effects on binding of a photopolymerizable composite resin prosthesis for metals Precious and not precious [40]. After treating gold, gold alloys, silver alloys, Au -Ag -Pd alloys, and Ni -Cr alloys with the experimental primers, their SBSS with solidex were measured after 1 day storage followed by 5,000 thermal cycles .…”

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).
