| Indication in study | Deep bite ≥4 mm + excessive gingival display + normal vertical dimensions | Same |
| Patients | Postpubertal; mean age 20.9 yrs | Mean age 15.25 yrs |
| Appliance | 4 maxillary incisors bonded | 4 maxillary incisors + maxillary first molars banded |
| Initial leveling | 0.016″ and 0.016 × 0.022″ NiTi | Passive preformed NiTi utility arch |
| Working wire | 0.016 × 0.022″ SS anterior segment | 0.016 × 0.016″ blue Elgiloy |
| Miniscrew position | Distal to maxillary lateral incisors | — |
| Miniscrew size | 1.2 mm × 6 mm | — |
| Loading | 1 week after placement | — |
| Intrusion force | 80 g | — |
| Force application | Close to center of resistance | Through utility arch |
| Treatment duration | 6.61 ± 2.95 months | 6.61 ± 2.46 months |
| Intrusion rate | 0.44 mm/month | 0.27 mm/month |
| Incisor vertical movement | 2.97 mm | 1.81 mm |
| True intrusion at CR | 1.75 mm | 0.86 mm |
| Incisor protrusion | 0.79 mm — NS | 3.91 mm — significant |
| Incisor angular change | 3.85° — NS | 13.55° — significant |
| Molar movement | No significant movement | Distal tipping |
| Overbite reduction | 2.18 mm | 2.32 mm |
| Root resorption | No signs detected in miniscrew group | Not evaluated in this study |
| Main advantage | True intrusion + minimal protrusion + minimal posterior side effects | Effective overbite correction but greater incisor proclination and molar tipping |
