Table 2

Histomorphometric results of bone biopsies retrieved from sinuses augmented.

	MCBA (%)	FDBA (%)	ABB (%)	EB (%)	HA-β-TCP 30/70 (%)	BC (%)
Newly formed bone	20.1	32.1	16.1	22.8	20.3	21.4
Marrow spaces	57.5	47.8	46.7	47.1	41.8	53.3
Residual graft material	22.4	20.1	37.2	30.1	37.9	25.3

MCBA: mineralized solvent-dehydrated bone
FDBA: freeze-dried mineralized bone allograft
ABB: anorganic bovine bone
EB: equine-derived bone
HA-β-TCP 30/70: synthetic micro-macroporous biphasic calcium-phosphate
BC: Bioapatite-collagen.
