RESUMO

Recent developments on the field of imaginology allowed computed tomography to become largely used in dentistry. Details of anatomic structures can be visualized with high quality images and measurements can be taken on several plans helping all professionals involved on the treatment of patients with alveolar bone defect, malocclusion and facial deformities caused by cleft lip and palate. Objectives: to evaluate tooth tipping and long axis angulation of mandible and maxilla anterior teeth produced by corrective orthodontic treatment in patients with unilateral cleft lip and palate and to analyze the morphology of alveolar bone and teeth roots after orthodontic treatment in the same group of patients. Methods: Ten patients that had received orthodontic treatment at the Craniofacial Anomalies Rehabilitation Hospital (HRAC-USP) were selected and submitted to computed tomography exam. All images taken during the exam were transferred to Dolphin Imaging Software and specific areas of anterior teeth were selected to be cutted. Measurements were taken and submitted to statistical analyses. Results: There were statistical differences between measurements of anterior teeth on both sides of the upper arch and the alveolar bone and roots interface could be well visualized. Conclusion: The results showed that this method is reliable and reproducible; however, new researches are necessary.
