Table 3

Mean fracture resistance values, standard deviations, and statistical categories of all experimental groups ().

Groups	Material	Fracture strength mean values (N)	Standard deviation (SD)
CO	Control	3959.00^a	1279.79
EC	IPS e.max CAD	2408.00^b	607.97
LU	Lava Ultimate	2206.73^b	675.16
EL	IPS Empress CAD	2573.27^b	644.73
EP	IPS Empress Esthetic	2879.53^b	897.30

Groups with different superscript letters are statistically significantly different according to the Tukey HSD test (). ^aDifferent superscript letters in same column indicates significant difference (). ^bSame superscript letters in same column indicates no significant difference ().
