The purpose of the present study was to assess the thickness of the alveolar process on the anterior region of maxilla and mandible of patients with antero-posterior discrepancy. The thickness of the alveolar process on the anterior regions of maxilla and mandible was measured by lateral cephalograms from fifty two patients with ages between seven to thirteen years. All the patients included on this study had the mandibular plan angle between 20 and 30 degrees and antero-posterior bone discrepancy between maxilla and mandible. The statistical analysis (Chisquare test) revealed independence between the thickness of the maxilla and mandible alveolar process and the patient age. However, a statistical dependence was found between the type of the malocclusion and the thickness of the buccal bone on anterior region of maxilla. The patients with Class III malocclusion showed a higher percentage of buccal bone reduction on the anterior region of maxilla when compaired with Classe II patients. The patients with trend to vertical growing had a reduced dimension of the maxilla lingual bone and mandible buccal region.
