Table 2. Mean difference of percent vital bone, residual graft, and others between test and control group.

Notes: Data was presented as mean±SD, and an independent sample t-test was used to estimate the p-value

	Control group (n=30)	Test group (n=30)	p-value
Vital bone, %	38.4±12.5	42.6±1.76	0.076
Residual graft, %	14.3±6.80	7.69±1.78	<0.001
Others, %	52.5±7.97	43.9±1.03	<0.001
