Comparison of the mean values of initial and post-loading removal torque in each group.
| Group | Initial R/T a | R/T after Static Load b | Significance † |
|---|---|---|---|
| Ext | 24.22 ± 0.81 | 22.78 ± 0.40 | * |
| Int-H2 | 21.22 ± 1.04 | 11.62 ± 0.56 | ** |
| Int-H1 | 27.44 ± 0.92 | 36.38 ± 6.25 | NS |
| Int-O2 | 25.38 ± 1.86 | 1.14 ± 0.40 | * |
| Int-O1 | 30.54 ± 0.56 | 39.64 ± 4.28 | * |
a Removal torque values before loading; b Removal torque values 700 N static loading; † Paired t-test was performed to compare the removal torque values before and after loading: NS, not significant; * p < 0.01; ** p < 0.001.
