“…These results arise from four main effects due to glow discharge: etching, or ablation; an increase in microroughness, the generation of radicals; and plasma polymerization. Plasma treatments can also improve adhesion in adhesive polymer or metal polymer systems by increasing one or several of the following phenomena: the cleaning by ablation of low‐molecular‐weight species, dehydrogenation, chain scission combined with crosslinking, generation or incorporation of radicals and reactive species, structural modifications of the surface topography, and so on 22–24…”

Dental ceramic is one of the most widely used materials in the dental industry because of its extensive use in resin‐bonded restorations and porcelain repair systems. In this study, two approaches were applied to dental ceramic surfaces for improvement in the wettability and surface energy of the effective resin–ceramic interfacial binding. One group of dental ceramics was treated by glow discharge with oxygen at a discharge power of 20 W and for an exposure time of 15 min. The other group was dipped onto hydrofluoric acid (HF) solution. Then, the samples were washed with distilled water and dried at the room temperature before the oxygen plasma treatment. The effectiveness of the two approaches was compared by means of changes in the surface wettability and polarity as measured by both the sessile drop and captive bubble techniques. Oxygen plasma treatment increased the surface wettability, but a greater increase was found with HF etching before the oxygen plasma treatment. This result was demonstrated by the decrease in the static contact angle as measured by the sessile drop technique (53.6 ± 4.19 to 27.7 ± 3.30). In addition, with the combination of the prechemical treatment with HF and the oxygen plasma treatment, the polarity increased more dramatically (0.706 ± 0.013 to 0.845 ± 0.008). The surface chemical composition and physical morphology were investigated by X‐ray photoelectron spectroscopy and scanning electron microscopy. Furthermore, the HF etching before oxygen plasma treatment was found to improve the shear bond strength, and it was significantly stronger than that of the groups treated with oxygen only for the resin composite materials (p < 0.05). This two‐step treatment could be a new approach for the activation of dental ceramic discs. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Bonding between oxide ceramics and adhesive cement systems: A systematic review

et al. 2013

View full text Add to dashboard Cite

The following aims were set for this systematic literature review: (a) to make an inventory of existing methods to achieve bondable surfaces on oxide ceramics and (b) to evaluate which methods might provide sufficient bond strength. Current literature of in vitro studies regarding bond strength achieved using different surface treatments on oxide ceramics in combination with adhesive cement systems was selected from PubMed and systematically analyzed and completed with reference tracking. The total number of publications included for aim a was 127 studies, 23 of which were used for aim b. The surface treatments are divided into seven main groups: as-produced, grinding/polishing, airborne particle abrasion, surface coating, laser treatment, acid treatment, and primer treatment. There are large variations, making comparison of the studies difficult. An as-produced surface of oxide ceramic needs to be surface treated to achieve durable bond strength. Abrasive surface treatment and/or silica-coating treatment with the use of primer treatment can provide sufficient bond strength for bonding oxide ceramics. This conclusion, however, needs to be confirmed by clinical studies. There is no universal surface treatment. Consideration should be given to the specific materials to be cemented and to the adhesive cement system to be used.

The capacity of tin oxide films to support cell growth was investigated. Three substrates were used for the test: glass coverslips, glass coverslips spin coated with tin oxide and commercially available 316 stainless steel. The wettabilities and surface roughness of the three surfaces were measured before seeding 3T3 fibroblasts onto the samples. The behaviour of the cells grown on the tin oxide was compared to the uncoated glass and the steel and results showed that the cell growth on tin oxide compared favourably with the other substrates. The surface wettability appeared to have the strongest effect on cell adhesion to tin oxide.
