Mean bone height (BH) loss and mean resorption rate over time

	Mean BH loss (mm)*	Mean resorption rate (%)**
Th	1.33 ± 0.81	14%
Ti	2.00 ± 1.88	21%
T1	2.29 ± 1.70	24%
T2	2.55 ± 1.68	26.8%
T3	3.05 ± 1.63	32%
T4	4.02 ± 1.50	42.2%
T5	4.12 ± 1.82	43.2%
T6	4.05 ± 1.83	42.5%

Th: 3 months post-augmentation, Ti: at implant installation, 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

*BH at Th and Ti differed significantly. BH at T2 and T3, and T3 and T4 differed significantly. BH at T4, T5, and T6 did not differ significantly (p < 0.05)

**Mean bone height gained after augmentation was 9.53 ± 4.78 mm
