Distal movement of maxillary canines and premolars with sectional mechanics following Distal Jet application to molars [Utilizzo dei sezionali di arretramento per premolari e canini superiori dopo la distalizzazione molare con Distal Jet]

Objectives: to assess the effectiveness of Distal Jet without simultaneous fixed appliance treatment. Subjects and 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. Conclusion: 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.
