HENRY SCHEIN ORTHODONTICS INTRAORAL MOTION 3D CLASS II APPLIANCES How the CLASS II Appliance Works The MOTION 3D Class II Appliances are used to employ the SAGITTAL FIRST ™ Philosophy to achieve an ideal Class I platform at the beginning of treatment prior to placing brackets or aligners when there are no competing forces operating and patient compliance is at its highest. Setup: O Appliance is bonded from the upper first molar to the cuspid or bicuspid O Bondable hook or molar tube is bonded to the lower first or second molar O Elastics connect the appliance to the bondable hook or molar tube O Essix-type retainer, clear aligner, or lingual arch provides anchorage for mandibular arch Using gentle, uniform forces, the MOTION 3D Appliance achieves ideal Class I occlusion by simultaneously: 1. Rotating the maxillary first molars around the palatal root 2. Uprighting the maxillary first molars 3. Distalizing the maxillary posterior segment - from canine or first premolar to first molar, as a unit Before MOTION 3D After MOTION 3D Before MOTION 3D After MOTION 3D Results from MOTION 3D : 1.
