Objective: To determine the prevalence of malocclusions in the three spaces planes in patients with dyslalias treated at the graduated functional orthopedics and orthodontic program at the Universidad Cooperativa de Colombia, Bogotá branch from January to July 2012. Materials and Methods: A transversal descriptive study was held in study casts models and craniofacial radiographs from patients 5 years and older diagnosed with dyslalia. The Bjork method of malocclusion record was applied at the vertical, transversal and sagittal and space abnormalities. In order to determine the skeletal maxilomandibular relationship at the sagittal plane the McNamara analysis was applied. The statistical analysis for malocclusion was held trough analysis of frequency and percentage. Results: The prevalence of malocclusions in patients diagnosed and evaluated was 68.3% sagittal, 51.2% vertical, 19.5% transversal and a 36.6% of space abnormalities. Conclusions: Class I malocclusion had the higher prevalence, the relation between skeletal class II division I with increased over jet and dyslalia was not found.
