The Fixed Pendulum/Expansion Appliance (FPAE) affects simultaneous maxillary expansion and posterior (backward) movement of the molar teeth to create space for permanent teeth to erupt naturally while also improving the bite (fit and function of the teeth).

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.

A Pendulum spring on one side can regain space without putting undue strain on other parts of the upper arch. A fixed rapid palatal expander with incorporated Pendulum appliance can accomplish dual purpose of rapid maxillary expansion and molar distalisation [ 3 ].

The pendulum-expander (Pendex) appliance is a fixed active appliance that is designed to both widen the upper jaw and move the molars in a backwards direction. This typically serves to correct both crowding, and in some cases, flaring of the front teeth.

Perfect for your non-compliant patients, the Pendulum is a fixed appliance for distalization and rotation correction of the upper first molars. Palatal vault acrylic is used in conjunction with wire rests that are bonded to the occlusal surface of the bicuspids to provide anchorage.

In about 25% to 30% patients’ upper arch expansion is beneficial and 95% of Class II patients can get better by using molar distalization, rotation and expansion. Molar distalization with headgear and elastics needs patient co-operation.

Jan 3, 2022 · What does a pendulum appliance look like? Hidden behind your front teeth, the pendulum appliance resembles a palatal expander. At the center of this appliance is an acrylic plate with two metal loops (bands) secured around your top first molars.

What Does a Pendulum Appliance Treat? A pendulum orthodontic appliance helps to create more room in a patient’s mouth by widening the upper jaw and shifting a patient’s top molars back to provide more room for crowded teeth to move into alignment. Pendulum appliance uses include: Treating Overbites.

The Hilgers Pendulum appliance is an innovative orthodontic device specifically designed to distalize the upper molars for the effective correction of Class II malocclusions. This appliance achieves optimal arch development through the use of rests on the premolars and a .032 TMA wire embedded in acrylic.

What is a Pendex Appliance? A Pendex appliance is a fixed orthodontic device used to expand the jaw, thus fixing a series of issues. It works based on an expansion screw and springs which push the top teeth backward. With this, it allows a correction of the upper jaw and proper alignment of the teeth.
