5. Study Description

Brief Summary
The posterior crossbite is a common type of malocclusion that might affect the normal growth pattern. Early treatment is recommended by rapid maxillary expansion with different appliances. This line of treatment needs a sufficient retention period to decrease the rate of relapse. The low level laser therapy has been used to enhance tissue regeneration. This study aims to compare the effect of rapid maxillary expansion with low level laser versus rapid maxillary expansion in children with posterior cross bite malocclusions.
Detailed Description
This study aims to evaluate the effect of rapid maxillary expansion using the bonded Hyrax expander combined with low level Laser therapy versus rapid maxillary expansion alone. The investigators intend to recruit sixty subjects of both sexes, between the age of 7 and 14 years. Patients with posterior crossbites and patent Mid-palatal sutures will be randomized into one of the two groups of treatment. Full orthodontic records will be collected and the standard orthodontic radiographs will be replaced by cone beam computer tomographic images. The records will be taken before the maxillary expansion and after 6 months of retention. The skeletal, dentoalveolar, and soft tissue effects of the two interventions will be compared.
