“…In one, cell viability rate was not statistically significant at 24 h when comparing Suprinity ® with zirconium. However, the initial apoptosis rate was significantly higher in the zirconium [ 28 ]. In the other study, cell viability was studied at 24 h in two surface treatments.…”

New zirconia-reinforced lithium silicate ceramics (ZLS) could be a viable alternative to zirconium (Y-TZP) in the manufacture of implantological abutments—especially in aesthetic cases—due to its good mechanical, optical, and biocompatibility properties. Although there are several studies on the ZLS mechanical properties, there are no studies regarding proliferation, spreading, or cytomorphometry. We designed the present study which compares the surface, cellular proliferation, and cellular morphology between Y-TZP (Vita YZ® T [Vita Zahnfabrik (Postfach, Germany)]) and ZLS (Celtra® Duo [Degudent (Hanau-Wolfgang, Germany)]). The surface characterization was performed with energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), and optical profilometry. Human gingival fibroblasts (HGFs) were subsequently cultured on both materials and early cellular response and cell morphology were compared through nuclear and cytoskeletal measurement parameters using confocal microscopy. The results showed greater proliferation and spreading on the surface of Y-TZP. This could indicate that Y-TZP continues to be a gold standard in terms of transgingival implant material: Nevertheless, more in vitro and in vivo research is necessary to confirm the results obtained in this study.

“…Rau et al reported that the chemical resistance and corrosion rate of magnesium alloy were improved with the application of a glass-ceramic coating [26].Chemical durability is also important because leached ions during corrosion may not be safe. The literature demonstrated the cytotoxicity of materials in ceramic [27][28][29][30]. Elshahawy et al reported that Zn had the highest cytotoxicity (60% cell viability) to fibroblast cells among the ions released from gold alloys and ceramic crowns in patients' saliva, followed by Cu > Ag > Pd > Al > Au > Si.…”

“…The cytotoxicity was not related to the amount of the ion released in this study; Si had the highest released amount, but the least cytotoxicity (90% cell viability). This indicates Si has higher biocompatibility [28].Another study analyzed the medium where all-ceramic and provisional materials were immersed and found the materials leached to be slightly cytotoxic [30].Research has shown that silicon carbide (SiC) is a promising ceramic material for biomedical applications [31][32][33]. This material has superior properties including lightweight, high strength, corrosion resistance, and high temperature resistance [31][32][33][34][35][36][37][38][39][40][41].…”

Novel Coating to Minimize Corrosion of Glass-Ceramics for Dental Applications

et al. 2020

The effect of a novel silicon carbide (SiC) coating on the chemical durability of a fluorapatite glass-ceramic veneer was investigated by examining weight loss and ion release levels. The hypothesis that this novel coating will exhibit significant corrosion resistance was tested. Inductively coupled plasma atomic emission spectrometer (ICP) was used for ion concentration determination and scanning electron microscopy (SEM) for surface morphology analyses. Samples were immersed in pH 10 and pH 2 buffer solutions to represent extreme conditions in the oral cavity. Analyses were done at 15 and 30 days. The SiC coated group demonstrated significant reduction in weight loss across all solutions and time points (p < 0.0001). Ion release analyses demonstrated either a marginally lower or a significantly lower release of ions for the SiC-coated disks. SEM analysis reveals planarization of surfaces by the SiC-coated group. The surfaces of coated samples were not as corroded as the non-coated samples, which is indicative of the protective nature of these coatings. In conclusion, SiC is a novel coating that holds promise for improving the performance of ceramic materials used for dental applications.Materials 2020, 13, 1215 2 of 11 substances pH 8-14 (e.g., spinach, soybeans, and antacids) [1]. Eventually, this constant change in pH can decrease the fracture strength of glass-ceramics [13,14] and increase surface roughness [15,16]. This roughening of the restoration can lead to plaque accumulation and increased wear of the opposing enamel [17,18]. Dental restorations should be able to withstand these fluctuations in pH.Chemical durability of dental materials has been extensively studied because of the importance of this property on the longevity of the restoration. Intrinsic or extrinsic modifications can be used to improve chemical durability. Several studies have demonstrated chemical stability for glass-ceramics can be enhanced by (1) different ratio of compositions; (2) addition of oxides, such as CaO, K 2 O, and Al 2 O 3 ; and (3) fluorine and calcium phosphates as part of intrinsic modifications [19-23]. Extrinsic modification can be achieved by producing additional layers on the surface to enhance chemical durability and other physical properties [24-26]. Esquivel-Upshaw et al. showed that glazed material has better chemical resistance than non-glazed material [1]. Topateş et al. discussed the effect of different glaze compositions on chemical durability [25]. Rau et al. reported that the chemical resistance and corrosion rate of magnesium alloy were improved with the application of a glass-ceramic coating [26].Chemical durability is also important because leached ions during corrosion may not be safe.
