Various different Pendulum appliances have been presented and articles written. However, the appliance shown in the photo above was developed to make improvements on previous versions. The aim was to develop the simplest, easy to handle appliance that would allow the patient to maintain good oral hygiene. It was also essential to obtain a most effective distalization.

Components:

   1. Base with the attachment tubes
   2. Anchorage wires
   3. Bite planes
   4. Molar bands with Goshgarian tubes
   5. Preformed distalizing springs

The items 1 to 3 could be classed as the anchorage components and the items 4 and 5 as the active parts of the appliance.

Clinical conditions for treatment with the modified Pendulum Appliance:

• The wisdom teeth must be removed.

• The root típs of the molars should not have contact with the base of the sinus. Prior to treatment an O.P.G. x-ray or if available a three dimensional x-ray should be taken.
