Table 4 Marginal bone loss (MBL) of dental implants placed on the augmented bone at evaluated time points

From: Rehabilitation of atrophic jaw using iliac onlay bone graft combined with dental implants

  MBL compared to installation (mm)* MBL compared to previous time point (mm)**
T1 0.32 ± 0.21 0.32 ± 0.21
T2 0.51 ± 0.24 0.19 ± 0.14
T3 0.85 ± 0.44 0.34 ± 0.29
T4 1.03 ± 0.53 0.12 ± 0.20
T5 1.19 ± 0.57 0.15 ± 0.18
T6 1.12 ± 0.50 0.10 ± 0.16
  1. T1: 3 months after installation, T2: at prosthetic loading, T3: 1 year after installation, T4: 2 years after installation, T5:3 years after installation, T6: 5 years after installation
  2. *Mean MBL at T1, T2, T3, and T4 was significantly higher than at implant installation (p < 0.05)
  3. **Mean MBL change compared to previous time point significantly differed between T2 and T1, T3 and T2, and T4 and T3. MBL change at T4, T5, and T6 was not differ significantly (p < 0.05)
