En-masse Distalization of Maxillary Arch with Modified Hybrid Hyrax Appliance: A Case Report

Class II malocclusion is one of the most commonly seen malocclusions in the orthodontic practice, with a variety of treatment modalities found in the literature. Maxillary molar distalization is a one of treatment options of dental Class II patients with excessive overjet, anterior crowding, or both. However, a commonly seen side effect in the conventional distalization devices is anchor loss. Here, in this case report, we have shown the successful treatment of a Class II malocclusion patient with a new concept of modified placement of the hybrid hyrax appliance, which was used effectively for en-masse, bodily distalization of maxillary teeth, with no anchorage loss. Also, the same appliance could be used for retention after the active distalization period till the treatment completion.
