Summary

There is a scarcity in the current literature regarding such appliance and its effect on distalizing the first maxillary molar in absence of the second molar. Therefore, this study was made to evaluate the effect of bilateral distalization of upper first molars in a group of patients after extraction of maxillary second Molars using infra zygomatic mini implants.

Detailed description

The appliances available for distalization used to be mainly extraoral distalizing appliances which depended entirely on patient cooperation and compliance. Even after the emergence of intra-oral distalizing appliances they had adverse dentoalveolar effect such as anchorage loss and flaring of the upper anterior teeth. Thus, this study was made in order to evaluate the efficiency of our proposed appliance in the treatment of Class II patients while avoiding the adverse effects mentioned above.

Conditions

• Class II Malocclusion

Interventions

Type	Name	Description
DEVICE	Intra-Oral Distalizing Device	The inner bow (1.2mm) is a modified version of the inner part of a conventional face bow. Two hooks were soldered onto the inner bow distal to the lateral incisor teeth regions, and U loop at 1st premolar region, and bends acting as mesial stop will be bent in front of the maxillary first molars. The anterior component of the inner bow is 3 mm free from the labial surface of anterior teeth
