Clinical Trial Summary

This study aims to evaluate the Skeletal and Dento-alveolar expansion in adult patents using Four Mini-screws Supported Hyrax in compare with untreated control group.


Clinical Trial Description

Aim of the study: To evaluate the Effectiveness of Four Mini-screws Supported Hyrax for Maxillary Expansion in Early Adulthood Methodology: - Essential record for orthodontic treatment will be taken. - impression with bands on upper first molars will be taken. - Four 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. - The appliance will be cemented 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 ;
