Stability of simultaneously placed dental implants with autologous bone grafts harvested from the iliac crest or intraoral jaw bone

Table 2 Implant survival rate at all follow-up period and the ratio of residual grafted bone height at T5

		No. of patients/No. of fixtures	Implant Failure			Overall Implant Survival Rate*	Ratio of Residual Grafted Bone Height at T5**
		No. of patients/No. of fixtures	Early (~T2)	Middle (T2 ~ T4)	Late (T5~)	Overall Implant Survival Rate*
Subantral Inlay Graft	Gr1	18/77	0	3	1	94.8 %	51.9 %^a

*There is no statistically significant difference in implant failure rate and overall implant survival rate between the two groups (p > 0.05)
**The ratio of residual grafted bone height was calculated at T5 by comparing the initial increased bone height at T1: [(remaining grafted bone height at T5)∕(initial increased bone height at T1) × 100]
^a,b: different letters indicate the statistical difference between Group 1 and Group 2 (p < 0.05)
