Piggy back
Double wire technique
After space gaining And teeth aligning
Then bite levering to cross the underbite
We use 16x22 St-St wire as main arch wire with segmented wire 12 NiTi for impacted tooth traction with maximum bend on impacted tooth not exceed 30 degree
Anchorage gained from all arch as maximum
Traction by 12 NiTi wire with bend not more 30°
