Measurements of height and width of mucosal and the W/H

Items	T0				T1				T2
	H/mm, x±s	W/mm, x±s	W/H		H/mm, x±s	W/mm, x±s	W/H		H/mm, x±s	W/mm, x±s	W/H
T0, before loading; T1, one month after loading; T2, one year after loading. H, height; W, width; W/H, width-to-height ratio. Group A, mucosal thickness ≥ 2 mm; Group B, mucosal thickness < 2 mm; Groups A1 and B1, control group with healing abutment emergence profile; Groups A2 and B2, test group with altered emergence profile. * The W/H at T2 in the control group was significantly different from those at T0 and T1 in both thick and thin gingival group. # The W/H at T0 in the test group was significantly different from those at T1 and T2 in the thick gingival group.
