Precision parameters measurement of each study group.
| Parameters | RAG | FHG | P-value |
|---|---|---|---|
| EPD (M ± SD) (mm) | 0.70 ± 0.33 | 4.16 ± 2.21 | 0.000 |
| TRA (M ± SD) (°) | 1.3 ± 0.8 | 11.9 ± 5.6 | 0.000 |
EPD = entry point deviation; FHG = free-hand technique group (conventional group); M = mean; RAG = “Orthbot”-assisted group; SD = standard deviation; TRA = trajectory rotation angle.
