Mean and standard deviations (±SD) for overall gap measurements (mm³).

	Crown type
Tooth number	CAD/CAM	Prefabricated fiberglass
51	3.08 (0.38)^Aa	8.15 (0.74)^Ab
53	2.93 (0.48)^Aa	5.82 (0.61)^Bb
75	5.15 (0.56)^Ba	11.99 (0.61)^Cb

Different superscript uppercase letters (A, B, C) in the same column and different superscript lowercase letters (a, b) in the same line indicate statistically significant difference ().
