Aim: To characterize the occlusion and facial pattern to diagnose the rehabilitation requirements of patients with cleft of lip and palate from Center for Treatment of Craniofacial Anomalies of Rio de Janeiro state. Methods: A sample of 20 cleft lip and palate patients, operated of lip and palate, without orthodontic treatment were selected. The transversal dimensions and morphology of maxillary dental arches, as well as facial pattern and inherent characteristics of rehabilitation process were evaluated. Transversal dimensions were compared with a normal occlusion group (n=22). Results: Data indicated transverse maxillary deficiency associated to different kinds of cross-bites in the cleft group. Facial profile shows strong tendency for maxillary hypoplasia, while alveolar bone graft was absent in the rehabilitation process. Conclusion: The findings suggest the impact of primary surgeries of lip and palate on the three-dimensional growing of maxilla. The gold pattern of rehabilitation cannot be reached without alveolar bone graft, a therapy that provides unity and integrity to alveolar maxillary bone.
