简要总结
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.
详细描述
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
