“…In addition, when polished with different polishing materials, ΔE* VE values were at an acceptable level for all the ceramic materials. All these values [ 21 , 28 , 32 ] are slightly lower than the VE values of the present study despite that all ΔE* are clinical in acceptable range (1 < (ΔE*—< 3.7) [ 18 , 22 ].…”

“…Although the recorded ΔE* values were 1.96 (VS), 2.65 (VM II), and 3.07(VE) within the clinically acceptable values for the three tested materials, these values are consistent with Subaşi et al [ 30 ] (slightly above 2) for VS, Sarikaya et al[ 18 ] (2.094) for VM II, and Colombo et al[ 31 ] (< 3.3) for Zirconia. However, ΔE* values were lower than (3.83 and 4.9) recorded by Saba et al [ 17 ] for VE and VM II and Abu-Obaid et al[ 32 ] (< 3.3 for VE, VM II, VS). However, the values were higher than that of Alp et al[ 12 ] and Al Moaleem et al [ 14 ] who documented lower values than 1.0 for VS and 0.73 for VM II and Zirconia.…”

“…Those values were slightly higher but somewhat lower than the values obtained (3.17–3.56) for VE polished samples [ 16 ], and this range was clinically acceptable. Abuobaid et al [ 32 ] recorded ΔE* 2.54 ± 0.27 for polished VE and 1.17 ± 0.59 for reglazed samples. Vasiliu et al[ 28 ] documented 1.35 for the hybrid ceramic, after being exposed to hot and cold coffee.…”

Background The purpose of this study evaluates and compares the effect of surface roughness (Ra) and color stability on computer-aided design/computer-aided manufacturing (CAD/CAM) hybrid resin (Vita Enamic), feldspathic (Vitablocs® Mark II), and lithium disilicate Zirconia (Vita Suprinity) glazed or polished ceramics immersed in hot Arabic Qahwa and cold coffee. Methods A total of 96 standardized samples were prepared from CAD/CAM restorative materials. Half of the samples were polished as per the manufacturer’s instructions using a porcelain polishing kit, and the other half were glazed. Samples were distributed and immersed in hot Arabian Qahwa and cold coffee followed by thermocycling. Ra measurements and color changes were conducted before and after immersion. SEM images were captured from each type of glazed or polished ceramic. One-way ANOVA paired Student’s t-test, and Bonferroni test were conducted to detect significant difference between the groups. P > 0.05 was a significant level. Results Of all the tested samples, Ra increased without any significant difference; however, mean color changes (ΔE*) showed significant differences. An increase in Ra was noted for all the glazed and polished samples after immersion and thermocycling. However, differences were significant only in VM II. In addition, ΔE* was significant only in Vita Suprinity (VS) samples. For immersion groups, significant Ra changes were noticed in glazed samples, only in Vita Enamic (VE) with no ΔE*. In polished samples, mean Ra changes were observed in VM II and VS samples. Significant differences were also noticed in polished VE and VS subgroups of ΔE*. Conclusions Ra affects all the tested samples, providing higher values on the polished specimens. The ΔE* caused by hot Arabic Qahwa and cold coffee on glazed or polished CAD/CAM restorative materials were clinically acceptable.

“…Ponadto adhezyjne połączenie materiału ceramicznego z twardymi tkankami zęba korzystnie wpływa na wytrzymałość konstrukcji protetycznej. [1][2][3][4][5][6][7] Ze względu na niedostateczną wytrzymałość mechaniczną i kruchość predysponującą do złamań i pęknięć, początkowo wskazania do stosowania uzupełnień całoceramicznych ograniczały się jedynie do pojedynczych koron i licówek oraz krótkich mostów w przednim odcinku łuku zębowego. Znaczny postęp technologiczny i rozwój materiałoznawstwa stomatologicznego, który dokonał się na przestrzeni ostatnich trzech dekad pozwolił na wykonywanie rozległych, wytrzymałych konstrukcji całoceramicznych również w obrębie zębów trzonowych.…”

“…In addition, the proper adhesion of ceramic material to hard dental tissues has a positive effect on the strength of the structure of the restoration. [1][2][3][4][5][6][7] Due to insufficient mechanical strength and brittleness predisposing to fractures and cracks, the indications for the use of allceramic restorations were initially limited to single crowns and veneers as well as short bridges in the anterior segment of the dental arch. Significant technological progress and the development of dental materials science, which has taken place over the last three decades, made it possible to extend durable, allceramic constructions to the molar region.…”

Due to the rapid development of materials science and production technologies in dentistry, especially computer-aided techniques in recent years, the range of indications to apply fullceramic fixed restorations not only in the anterior segment of the dental arch but also in the premolar and molar region has considerably widened. Because patient's expectations relating to the aesthetics of their dentition are constantly on the increase, more and more commonly fullceramic replacements become the first-choice of treatment for interdental gaps restoration and reconstruction of the dental hard tissues deficiencies. Among the types of ceramics known and currently used in manufacturing fixed restorations, glass-ceramics is used more and more often, as it is characterized by both high aesthetics and satisfactory parameters of mechanical strength. The aim of this publication is to systematize and compare the most commonly used types of glass-ceramics to produce full-ceramic fixed restorations. Their advantages and disadvantages and indications and contraindications to their application in various clinical cases have also been discussed.
