Distalization, Fixed Appliances

Hilgers Pendex

The Hilgers Pendex appliance is a versatile orthodontic device designed to achieve simultaneous distalization of the upper molars and expansion of the dental arch. It utilizes a .032 TMA wire embedded in acrylic, combined with an expansion screw and rests on the premolars, to facilitate effective arch development. The appliance generates a wide swinging arc of force from the midline of the palate to the upper molars, creating a pendulum motion that enhances molar movement. Additionally, an adjustment loop can be added to the spring to aid in the precise rotation of the molars. Lingual sheaths are spot welded onto the bands for added stability, and these can be provided by the lab to ensure a secure fit during treatment.

Treatment & Care

Pre-activation of the springs should be done before insertion. Bend the spring 90 degrees, so they are parallel to the midline of the palate. Be aware that 1/3 of compression is lost during placement. Insert the spring into the lingual sheath using finger pressure and a Weingart plier. Use an elastic o-ring to hold the spring to the band.

The patient should be seen every three weeks, and reactivation should be done if needed. If needed, hold the center of the helix with a bird beak plier and push the spring distally.

The typical rate of activation is one (1) 1⁄4 turn every three days. Most screws we use in mid-palate applications require five (5) activations per 1mm.

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.

More About Hilgers Pendex

Also Known As:

Pendex appliance, Modified Pendulum appliance

Who Made Me:

Dr. James Hilgers designed the Pendex as a hybrid of his Pendulum appliance and a Rapid Palatal Expander (RPE). First introduced in the early 1990s, the Pendex combines molar distalization with maxillary expansion, providing a dual function in orthodontic treatment. It was developed to address complex cases that require simultaneous molar movement and arch expansion.
