Using laser therapy to enhance maxillary expansion in children with crossbites
Effect of Rapid Maxillary Expansion with Low Level Laser Therapy Versus Rapid Maxillary Expansion in Children with Posterior Cross Bite
This study is testing if using laser therapy along with a dental device can help children with crossbites have better results from their orthodontic treatment than just using the device alone.

What this trial studies
This study evaluates the effectiveness of rapid maxillary expansion using a bonded Hyrax expander combined with low level laser therapy compared to rapid maxillary expansion alone. It aims to recruit sixty children aged 7 to 14 years who have posterior crossbites and patent mid-palatal sutures. Participants will be randomly assigned to one of the two treatment groups, and their orthodontic records will be collected before and after a 6-month retention period. The study will analyze the skeletal, dentoalveolar, and soft tissue effects of both interventions using advanced imaging techniques.
Who should consider this trial
Good fit: Ideal candidates are children aged 7 to 14 years with posterior crossbites and patent mid-palatal sutures.
Not a fit: Patients with poor oral hygiene, active periodontal disease, craniofacial abnormalities, or those who have had previous orthodontic treatment may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could improve treatment outcomes for children with posterior crossbites by enhancing tissue regeneration and reducing relapse rates.
How similar studies have performed: While the use of low level laser therapy in orthodontics is gaining interest, this specific combination of techniques is relatively novel and has not been extensively tested in prior studies.
