Three patients are demonstrated showing distal mandibular molar movement with the Jones Jig appliance. A modified lingual arch was fabricated between the first premolar and the first mandibular molar on the other side of the arch as an anchorage unit. The movement of the mandibular molar tooth was measured in three dimensions. Distalization and distal rotation of this tooth was achieved with minimal side effects Keywords: Mandibular molar distalization, Jones Jig appliance
