Abstract
The purpose of this study was to compare the lento-skeletal characteristics between functional and skeletal anterior cross-bite patients. Twenty-eight functional anterior cross--bite patients and thirty-one skeletal anterior cross-bite patients were selected as a test and a control group. Mean ages of the test and the control group were 9.6±1.8 and 9.8± 1.9, respectively. Lateral cephalograms were taken. Forty-nine cephalometric variables were measured and statistical
analysis was performed to find the morphological differences between the groups. Statistically significant differences were found in the cephalometric variables of cranial deflection, maxillary depth, ANB, convexity, NPo-AB APDL 1M1x 1-SN, Mx 1-NA angle, Mx 1-NA, Md 1-NB angle and Md 1-NB. The test group showed more Class III growth potential, more protruded maxilla, lesser maxillo-mandibular difference, more uprighted and retruded maxillary central
incisor, more labially tipped and protruded mandibular central incisor.
