Distal movement of maxillary canines and premolars with sectional mechanics following Distal Jet application to molars.
OBJECTIVE
to assess the effectiveness of Distal Jet without simultaneous fixed appliance treatment.


METHODS
twenty subjects with Class II malocclusion who received the Distal Jet appliance to move maxillary molars distally. Subsequently, the canine and premolar distal movements were achieved by the use of.017 x.025 Ni-Ti sectional wires and memory power chain.


RESULTS
revealed that Distal Jet is more effective with less anchorage loss when this appliance is used independent of multibracket appliances.


CONCLUSIONS
this study showed that Distal Jet is an effective and predictable appliance. The distal movements of upper premolars, canines and incisors with sectional wires fabricated from.017 x.025 Ni-Ti were biomechanically very effective, simple in clinical application, and did not require any patient compliance.
