To evaluate the changes of the position of the mandibular condyle in cleft lip and palate patients with secondary bony cross-bite deformity after early orthodontic treatment with extraoral bow and facial mask.
The TMJ topograph 6 months before and after treatment was investigated in 8 patients. The width of the anterior,superior and posterior space of the TMJ was compared prior to and post treatment.
The results showed that there was no significant difference in the width of the three spaces of the TMJ before and after treatment.
The position of the mandibular condyle had no significant change after maxillary anterior distraction with extraoral bow and facial mask.
