Abstract

Objective: To investigate mandibular symmetry, maxillary symmetry and condylar position in patients with functional unilateral posterior crossbite (FUPXB) using Multi-slice computed tomography (MSCT). Materials and Methods: 15 patients (mean age 13 ± 3 years) with FUPXB underwent MSCT scans. Skeletal and dental measurements were taken to assess mandibular and maxillary symmetry. Medial and Lateral Joint spaces were compared between normal and crossbite sides in those patients. Results: There were no statistically significant differences between crossbite and normal sides regarding skeletal and dental mandibular and maxillary measurements and regarding condylar position. Conclusions: patients with FUPXB showed mandibular and maxillary symmetry. Those patients revealed symmetric condylar position between normal and crossbite sides.
