Distal Jet

Distal Jet

The Distal Jet is constructed around a highly efficient piston, and tube principle, coupled with a controlled and defined force delivery. The Distal Jet is uniquely adapted to a bio-mechanic approach to maximize outcomes. Superior distalizer combines simple translation with excellent anchorage control and positive, simple molar retention with one appliance. Typical clinical situations for the Distal Jet are: Class II maxillary protrusion, Class II molar relations resulting from missing or blocked out teeth, and Class II subdivision (unilateral) cases. Expansion can also be achieved by adding a transverse screw.

Treatment & Care

  1. Remove separators and clear any debris from the interproximal areas. Seat the appliance completely, checking the fit before cementation. Check the passive fit of directors and bayonets – adjust as necessary.
  2. Mix cement, load bands and cement the appliance as a single unit, in a customary manner.
  3. After cement clean-up, remove stabilizing floss or wire before activation.
  4. The appliance is activated initially after cementation and at four-week intervals by complete compression of coil spring with the activation lock (see special note below).

How to Convert to a Nance

  1. After distalization is complete, convert the Distal Jet to a retainer.
  2. Peel the spring from the appliance with a Weingart plier.
  3. Slide the lock firmly against the stop and tighten the screw.
  4. Squeeze the end of the lock tightly onto the bayonet wire. Important: this prevents the appliance from becoming loose.
  5. An alternative option is to tie the lock and bayonet wire/molar sheath together with a steel ligature or elastic chain or thread.

Video Instructions


Molar rotations must be corrected before they are distalized. This is easily accomplished in the lab by bending rotational compensation into the double-back sections of the bayonets. Seat and cement as above, do not activate and recall in one month. Begin activation after molars are corrected.

This appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.
