Purpose:
To design a kind of appliance to open space for aligning cuspid which is buccally and gingivally malpositioned.This kind of appliance can also be used to open space for distal movement of the upper arch moderate protrusion.
Methods:
At first, two bands of maxillary cuspids were made, then the two cuspid bands and additional two molar bands were put on the teeth respectively. After the impression was taken and poured, the molar distal jet was fabricated on the model. Finally, it was worn and one piece of coil was used to apply force to remove the molars distally.
Results:
Four cases were treated using this appliance.Both molars were distally moved within three months, and the necessary space was gained for subsequent treatment.
Conclusion:
Maxillary molar distal jet is an effective appliance to open space and move the maxillary molars distally.
