Objective: Assess the condition of occlusal dental arches of children with complete bilateral cleft lip and palate (FLPb), followed at the School of Dentistry, USP by analysis of dental casts. Material and method: The sample consisted of models of the dental arches of 30 patients with FLPb (8 females and 22 males) with mean age of 6 years and 2 months underwent primary repair surgeries. After clinical examination, there were pictures intra / extra oral and molding to obtain the working models, which were classified by the Index of Bilateral, by three calibrated examiners. The Cronbach's alpha test and Spearman correlation analysis showed a high degree of reliability (p <0001) and reproducibility (p <0.001). The study of the correlation between prognosis and Gender, and prognosis and rehabilitation hospital for surgery was done only with the rates determined by the researcher, which were grouped into good regular and poor prognosis. Results: Of the 30 patients analyzed, classified by the Index of Bilateral resulted in 10% grade 1, 36.6% grade 2, 36.6% grade 3, 13.33% grade 4 and 3.33% grade 5. Only 16% had a poor prognosis, and prognosis associated with the gender showed no statistically significant difference (p = 0.207) during the application of the Likelihood Ratio Test. Likewise, no relationship was found between the prognosis and rehabilitation hospitals (p = 0.788). Conclusions: There was a high concentration of patients in good and regular forecasts, without regard to gender or the rehabilitation hospital for surgery.
