A 16-year-old Class II female patient was treated without tooth extraction. The upper first molars were distalized by the Pendulum appliance. After six months, the molars tipped significantly to the distal. To correct this side effect, we decided to upright the molars using skeletal anchorage. On each side, a mini-screw was inserted between first and second premolars in the buccal cortical plat...

JCO/JANUARY 2003 F devices are increasingly being used for molar distalization in Class II treatment because they eliminate the need for special patient compliance. These appliances fall into two main categories: intra-arch (such as the Distal Jet,* Jones Jig,* and Hilgers Pendulum**) and interarch (such as the Herbst*** and active springs). The spring appliances can be further divided into can...
