Abstract

Maxillary molar distalization is a treatment approach for patients with Class II malocclusions who do not require extractions and mesial movements of mandibular molars. The pendulum appliance is effective for distalization of the maxillary molars and independent of patient cooperation. This appliance can stabilize the maxillary premolars and use the palatal rugae area as an additional anchorage. However, caution is needed to control collateral effects, including increase of lower facial height, incisor protrusion and damage to the rugae area. This article reports the cases in which maxillary molar distalization achieved by pendulum appliance resolves the space problems and corrects the molar relationships.

Key Words: Pendulum appliance, Maxillary molar distalization, Correction of molar relationship.
