“…Vickers hardness was measured for three ceramic plates and two rod specimens. Zirconia had the highest value, and polished HP ceramics were significantly harder than glazed HP ceramics (Table 2), as was the case in previous studies (4,11). In 1998, al-Wahadni and Martin reported that the mechanical strength of polished ceramics was greater than that of glazed ceramics (4).…”

This study compared the wear characteristics of a heat-pressed lithium disilicate ceramic material opposed to feldspathic porcelain, a lithium disilicate glass ceramic, and zirconia materials. Ceramic plate specimens were prepared from feldspathic porcelain (EX-3 nA1B), lithium disilicate glass ceramics (e.max CAD MO1/C14), and zirconia (Katana KT 10) and then ground or polished. Rounded rod specimens were fabricated from heatpressed lithium disilicate glass ceramic (e.max press LT A3) and then glazed or polished. A sliding wear testing apparatus was used for wear testing. Wear of glazed rods was greater than that of polished rods when they were abraded with ground zirconia, ground porcelain, polished porcelain, or polished lithium disilicate ceramics. For both glazed and polished rods, wear was greater when the rods were abraded with ground plates. The findings indicate that application of a polished surface rather than a glazed surface is recommended for single restorations made of heat-pressed lithium disilicate material. In addition, care must be taken when polishing opposing materials, especially those used in occlusal contact areas. (J Oral Sci 58, 117-123, 2016)

“…A rough or smooth surface resulting from the polishing procedure after in-clinic occlusal adjustment can influence the amount of wear on the opposing antagonist 12. In previous studies related to the wear aspects associated with surface roughness of monolithic zirconia,679131415 the range of surface roughness of polished monolithic zirconia is known to be 0.04 - 1.11 µm and zirconia with a smooth surface generally induces less wear on the opposing specimen than zirconia with a rough surface. In this present case, the measured surface roughness (Ra) of zirconia was 0.21 µm.…”

Metal stain on monolithic zirconia restoration: A case report

et al. 2017

In restorative treatment using fixed dental prostheses, dentists should select appropriate restoration material among various types of dental materials. The strength, marginal fit, esthetics, wear resistance, biocompatibility, and cost are important factors in the choice of restoration materials. The present case showed a surface stain on a monolithic zirconia restoration that was due to wear between the monolithic zirconia restoration and the base metal alloy restoration. This phenomenon was confirmed by surface roughness measurement and electron probe micro-analysis.

“…Surface hardness and wear resistance of resin luting cements are essential material properties to overcome the abovementioned issues (7). While the wear characteristics of restorative materials have been extensively examined (8)(9)(10)(11), limited research is available in the area of resin luting cements.…”

Simulated localized wear of resin luting cements for universal adhesive systems with different curing mode

et al. 2018

This study evaluated the simulated localized wear of resin luting cements for universal adhesive systems using different curing modes. Five resin luting cements for universal adhesive systems were evaluated and subsequently subjected to wear challenge in a Leinfelder-Suzuki wear simulation device. Overall, 20 specimens from each resin luting cement were photo-cured for 40 s (dual-cure group), and 20 specimens of each material were not photocured (chemical-cure group). Simulated localized wear was generated using a stainless steel ball-bearing antagonist in water slurry of polymethylmethacrylate beads. In addition, scanning electron microscopy (SEM) observations of resin luting cements and wear facets were conducted. Significant differences in simulated wear and SEM observations of wear facets were evident among the materials in the dual-and chemical-cure groups. The simulated wear and SEM observations of wear facets of G-CEM LinkForce and Panavia V5 were not influenced by the curing mode.SEM observations of resin luting cements were material dependent. In most cases, dual curing appears to ensure greater wear resistance of resin luting cements than chemical curing alone. The wear resistance of some resin luting cements appears to be material dependent and is not influenced by the curing mode.
