| Mechanical | Biological |
|---|---|
| Reduces radius of the curve | Increased coronal irrigation |
| Decreased stress on instruments | Decreased risk of inoculating bacteria apically |
| Stable reference point | Decreased risk of packing debris apically |
| Decreased risk of procedural errors | Deeper insertion of irrigating needle |
| Improved tactile feedback | |
