Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* 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
