Linear measurements	BIC, %	40.38 (18.24–48.15)	10.59 (2.61–26.12)	0.027
	fBIC, mm	2.25 (1.95–2.38)	3.31 (3.08–0.87)	<0.001
	P-BC, mm	0.59 (0.00–1.27)	2.91 (2.51–3.44)	0.001
Measurements in the AOI	NB, %	42.54 (28.69–54.66)	6.56 (3.40–12.84)	0.006
	RBS, %	8.03 (0.00–19.01)	6.86 (0.00–23.66)	0.908
	NMT, %	53.46 (32.92–56.66)	84.94 (68.29–95.29)	0.002

Data are median (interquartile range) values.
= number of sites/dogs. TAV (mm³) = the total augmented volume; BIC (%) = the bone-to-implant contact; fBIC (mm) = distance between the implant platform and the first bone-to-implant contact; P-BC (mm) = vertical distance between the most-coronal buccal bone and the implant platform; NB (%) = newly formed bone; RBS (%) = residual bone-substitute material; NMT (%) = nonmineralized tissue.
