Introduction: This study aimed at evaluating the maturation stage of the midpalatal suture based on its morphology, using cone-beam computed tomography (CBCT) images in young post-adolescents individuals. Methods: The sample of this study comprised 112 patients, 68 females and 44 males, aged 16 to 20 years, consecutively selected in two private orthodontic clinics. The patients selected presented CBCT images in their initial orthodontic documentation, requested for orthodontic planning purposes. These images were exported to the Invivo5 program, where axial sections were obtained from the midpalatal suture for morphological evaluation. Two previously calibrated examiners interpreted the images in order to establish the stage of sutural maturation of each patient according to its morphological characteristics in 5 different maturational stages (stages A, B, C, D and E). The Kappa coefficient was applied for intra- and inter-examiner agreements and their values were 0.87 and 0.89, respectively. The significance level adopted was 0.05% for the statistical tests. Results: The maturational stages most observed in this study were C, D and E, (91.9%). In males, stage C was present in 52.3%, and for females this prevalence was 39.7%. Conclusion: The high prevalence of stage C in this age group may justify a clinical study to confirm the good prognosis for rapid maxillary expansion in post-adolescents individuals
