Abstract
The effect of Rapid palatal expansion (RPE) on condylar displacement and temporomandibular joint (TMJ) space using Cone-Beam Computed Tomography (CBCT) in a pediatric population is of interest. RPE with a Hyrax expander was done on 80 patients. Pre- and post-treatment CBCT scans were evaluated to measure condylar displacement (anterior-posterior and vertical) and TMJ joint spaces (anterior, posterior, superior and medial). RPE induces significant anterior and inferior condylar displacement and increases in TMJ joint spaces in growing individuals.
