Brief summary
This randomized clinical trial aims to evaluate and compare the effectiveness of the Quad Helix (QH) appliance versus Rapid Maxillary Expanders (RME) in treating posterior cross-bite in Egyptian children during the mixed dentition stage. The study will also assess patient comfort and pain levels associated with each appliance.
Detailed description
The study involves 20 orthodontic patients aged 9-12 years with posterior cross-bite. Group A will receive the Quad Helix appliance, while Group B will receive Rapid Maxillary Expanders. Evaluation will be based on orthodontic study models, clinical photographs, and various radiographs including CBCT. Treatment will continue until complete correction is achieved, followed by a 3-month passive retention period.
Interventions
DEVICEQuad Helix(QH) Appliance
It is a fixed orthodontic appliance fabricated using stainless-steel wire and soldered to bands on upper first permanent molars.
DEVICERapid Maxillary Expanders
It is a fixed expansion device bonded on the upper first permanent molars and pre-molars. Activation is done at a rate of 0.25 mm twice daily (two turns per day)

Masking description
It is an open-label study where both the participants and investigators are aware of the assigned intervention due to the nature of the orthodontic appliances used
Intervention model description
A randomized controlled clinical trial with two parallel groups. Patients are randomly assigned to either receive the Quad Helix appliance (Group A) or the Rapid Maxillary Expander (Group B)
