From: Long-term evaluation of factors affecting removal torque of microimplants
Age | Length of microimplant | Diameter of microimplant | |
---|---|---|---|
Self-drilling (n = 463) | |||
Removal torque (mean ± SD: 3.37 ± 2.00 N cm) | 0.024 | 0.221** | 0.007 |
Pre-drilling (n = 220) | |||
Removal torque (mean ± SD: 4.81 ± 2.82 N cm) | 0.004 | 0.012 | 0.230* |
