RESUMO

Objectives: (1) To evaluate tooth tipping and long axis angulation using computed tomography (CT), after orthodontic treatment in patients with bilateral cleft lip and palate. (2) Morphological evaluation of bone and dental structures and their relationship offered by CT. Methods: Ten patients with bilateral cleft lip and palate were select. Long axis´ tomography cuts of all upper and lower anterior teeth and a panoramic view were obtained in order to measure tooth tipping and angulation. All measurements were repeated after one month (M1 and M2) and submitted to statistical analysis. Results: The results showed no statistical differences between M1 and M2, however measurements for all upper teeth were higher compared to literature showing that for these patients, variation is rule not exception. Lower teeth measurements were much more uniform and predictable. Conclusions: This method produced very accurate measurements and computed tomography provides high quality images to evaluate the relationship between roots and alveolar bone like no other source available.
