Evaluation of Maxillary Expansion Using Clear Aligners' Therapy in Patients With Cleft Lip and Palate at the Mixed Dentition Stage

Condition(s) studied

Investigational drug(s) / intervention(s)

clear aligners: aligners made with 1mm thickness sheet and covering the whole palate

Study summary

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.

Eligibility

Primary outcome measure(s)

• Transverse dento-skeletal changes — six months
  Using pre and post treatment cone beam computed tomography (CBCT), 3D point identification and landmark development will be done. On the CBCT, skeletal transvers maxillary width, anterior, middle and posterior cleft width, intermolar, inter premolar and inter-canine widths will be measured.
