Summary

The study aiming at evaluation of the Skeletal and Dento-alveolar expansion in adult patents using Two Mini-screws Supported Hyrax compared with untreated control group.

Detailed description

Methodology: * Basic orthodontic record will be taken. * impression with bands on upper first molars will be taken. * Two eyelets will be soldered to the body of the hyrax appliance (size 10, Dentaurum, Germany). * CBCT will be taken while patient wearing 1 mm thickness vacuum on the lower arch to dis-occlude both arches. * Delivery, check the retention and fitness of the appliance. * Cementation of the appliance using band cement(compomer). * Using 3M contra-angle driver, the screws (Tomas screw size 10, Dentaurum, Germany) will be loaded and inserted. * Activation of the appliance by opening it two turns immediately, followed by two turns everyday till cross bite correction or appearance of midline diastema. * Closure of the device, and leave the appliance in-situ for five months as a retention. * Post-expansion CBCT will be taken and continue fixed orthodontic treatment. Outcome: skeletal and dento-alveolar expansion will be evaluated
