“…Previous researchers have noted that whereas the apatite-forming ability of AH treatment was reduced in vitro when used at high temperatures in a moist environment for a week, the apatite-forming ability of ACaHW treatment remained constant under these conditions [17]. Apatiteforming ability and bone-bonding ability are correlated [8,27]. Consistent with the findings of a previous study of surface apatite formation on SBF [18], here, we found that ACaHW treatment resulted in more sustained and steady growth of BICs than AH treatment, as shown by the BIC and NBIC values for the mesh group from 2 to 4 weeks (Fig.…”

Alkali and heat (AH) treatment forming sodium titanate has been shown to connect bioinert Ti metal and bone tissue. Artificial joints treated with this method have achieved extensive clinical application. Recently a new chemical treatment of Alkali-Calcium-Heat-Water (ACaHW) treatment forming calcium titanate was proposed. Notably, the apatite-forming ability of this treatment is greater than that of AH treatment, as verified in vitro. However, the early bone-bonding abilities of the two treatments have not been compared in vivo. To simulate clinical application, we treated a commercially pure Ti (Cp-Ti) mesh implant with AH or ACaHW. Then, using mechanical and histological methods, we compared the bone-bonding abilities of the two treatments early during the implantation process (2-4 weeks); untreated Cp-Ti mesh was used as a control. Because the mesh structure might influence bone-bonding ability, we compared these bonding abilities with values obtained at 4 and 8 weeks using a Cp-Ti implant with a plate structure. In the mesh group, histological comparisons at 2 and 3 weeks indicated that ACaHW treatment resulted in a bone-bonding ability similar to that of AH treatment; ACaHW exhibited a greater bonding ability than AH at 4 weeks. However, in tests of the plate group at later time points, such differences were not apparent. The results obtained here indicate that during the early stage of embedment, ACaHW treatment of Cp-Ti mesh implants yields a higher bone-bonding ability than AH treatment, thus providing a positive reference for future clinical applications.

“…Due to zirconia's favorable aesthetic characteristics, mechanical properties and biocompatibility, the use of ceramic systems based on zirconium oxide has become increasingly popular in dentistry, with polycrystalline yttrium tetragonal zirconia (Y-TZP) base materials for Prosthetic restorations of ceramic in fixed prosthesis. The clinical success of these restorations is based on a bond of solid and durable resin to restorative materials and Support structures of the tooth [44]. However, the establishment of a strong and stable zirconia binding has been shown to be difficult [45].…”

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).

Both bioactive ion chemistry and nanoscale surface modifications are beneficial for enhanced osseointegration of endosseous implants. In this study, a facile synthesis approach to the incorporation of bioactive Ca 2+ ions into the interlayers of nanoporous structures (Ca-nano) formed on a Ti6Al4V alloy surface was developed by sequential chemical and heat treatments. Samples with a machined surface and an Na + ion-incorporated nanoporous surface (Na-nano) fabricated by concentrated alkali and heat treatment were used in parallel for comparison. The bone response was investigated by microcomputed tomography assessment, sequential fluorescent labeling analysis, and histological and histomorphometric evaluation after 8 weeks of implantation in rat femurs. No significant differences were found in the nanotopography, surface roughness, or crystalline properties of the Ca-nano and Na-nano surfaces. Bone–implant contact was better in the Ca-nano and Na-nano implants than in the machined implant. The Ca-nano implant was superior to the Na-nano implant in terms of enhancing the volume of new bone formation. The bone formation activity consistently increased for the Ca-nano implant but ceased for the Na-nano implant in the late healing stage. These results suggest that Ca-nano implants have promising potential for application in dentistry and orthopedics.
