Evaluation of Maxillary Expansion Using Clear Aligners' Therapy in Patients With Cleft Lip and Palate at the Mixed Dentition Stage: A Pilot Study
The goal of this clinical trial is to learn if the aligners can expand upper dental arch in patients with cleft lip and palate at age of 6-8 years old to correct their collapsid archs. The main questions it aims to answer are: Does aligners can achieve transverse dento-skeletal changes? Does aligners can achieve anteroposterior and vertical dento-skeletal changes? Participants will: Wear sequence of aligners (each for 10 days). Visit the clinic every month for checkups. 3D x-ray and intraoral scan will be taken after completion of the aligners set to evaluate the intervention.
