“…This transformation is theorized to enhance the damage tolerance of zirconia ceramic material. (33)(34)(35)(36)(37) Results indicated a statistically significant difference in SBS between testing zirconia-tested generations. With the highest mean of SBS earned by the 5th generation.…”

“…Those studies found that using a hydrophobic phosphate monomer (MDP) improved the binding performance between zirconia ceramics and resin-based luting agents. (36)(37)(38)(39) Larsson, et al in 2019 (40) however, disproved the idea that transparent zirconia had a stronger bond strength than opaque zirconia since the outcomes from both materials were equal.…”

Do the different zirconia generations respond similarly to the same bonding protocol of selfadhesive resin containing MDP. Materials and Methods: Four groups of zirconia specimens were used (n=10 each): according to the generation of zirconia used: group Hi Translucent is generation 1, group Super Translucent is generation 2, group Top Translucent is generation 3, and group Esthetic Explore is generation 5. Ten zirconia cuboids were dry-milled of each of the 4-zirconia blocks using a CAD CAM milling machine then sintered in a ceramic oven. Forty composite cuboids 4X4were fabricated and cemented using self-adhesive resin cement containing MDP to each zirconia cuboid using custom constructed Plexi-Frames. All specimens were thermally cycled and subjected to shear bond strength in the universal testing machine. Results: The mean SBS was higher in EX group (30.58+ 11.9) followed by HT group (23.16+ 3.6), then TT group (21.59+ 6.6), and finally ST group (21.47+ 6.1). One-Way ANOVA revealed a significant difference in SBS between tested groups. Conclusions: The 5th generation of zirconia scored the highest mean SBS values. More surface treatment protocols should be suggested for each zirconia generation.

“…The specimens were loaded until failure, which was determined by an audible crack sound or a sudden drop in the load/deflection curve. The failure load, measured in Newtons, was recorded using computer software (Nexygen-MT-4.6 from Lloyd Instruments, Largo, FL) (19) .…”

Objective: Currently, there is no recommendation for the minimum number of remaining walls for Zirconia endocrown. Materials and methods: Fifty resin specimens were divided into 5 main groups according to the remaining wall number; group W0 no remaining walls, group W1 1 remaining wall, group W2 2 remaining walls, group W3 3 remaining walls, group W4 no missing walls. Ten resin dies for each group were fabricated using epoxy resin and assigned to each group. Resin dies from all groups were individually scanned using an extraoral scanner. Second generation zirconia monolithic (three mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) endocrowns were milled. All endocrowns were sintered according to the manufacturer's recommendations. After trial fitting, all endocrowns were cemented to their corresponding resin dies using resin cement. After 1000 thermal cycles alternating between hot and cold baths with 20-second immersions at 55±1º C and 5±1ºC, respectively, and a 10-second delay between each immersion, each specimen was fixed to the lower fixed part of a universal testing machine with a load cell of 5 kN at a crosshead speed of 0.5 mm/min. All specimens were loaded to failure, and recorded in Newton using computer software. Data were collected, tabulated and statistically analyzed. Results: Group W1 showed higher mean values (2933±733.61) followed by W0 group (2453.5±492.48), then W4 group (2187±576) and group W2 (2108.17±451.28) and finally W3 group (1992±205.63). At a 95% of confidence level, One-Way ANOVA revealed significant differences between tested groups (P= 0.033). Conclusions: There was a significant difference in fracture resistance between groups with different numbers of remaining walls. The mean fracture resistance values were not consistent with the number of remaining walls. The number of remaining walls is not directly proportional to the fracture resistance values.
