Results of new bone forming area quantitative analysis (mean±SD) %

Postoperative	Group A (n = 16)	Group B (n = 16)	Group C (n = 16)	Group D (n = 16)
4 weeks	7.41 ± 1.87	4.63 ± 2.48	7.67 ± 2.17	0.00 ± 0.00
8 weeks	13.36 ± 2.12	8.52 ± 1.59	13.61 ± 2.91	0.00 ± 0.00
12 weeks	38.56 ± 3.23	22.41 ± 2.39	39.75 ± 3.13	0.00 ± 0.00

The new bone forming area was analysed by ANOVA at four, eight, and 12 weeks postoperatively. The results showed that the new bone forming area had no significant difference between groups A and C (P > 0.05), but there was significant difference between groups A and B, groups B and C, groups A and D, groups B and D, and groups C and D (P < 0.05)
