"Introduction: Dentomaxilar anomalies (DMA) are the third most common oral pathology in Chile.Objective: To determine the frequent of dentomaxilar anomalies observed in patients treated in the Department of Orthodontic of Dental Specialties Service (DSS) belonging to the Barros Luco Trudeau Healthcare Complex, Santiago, Chile.The population belongs to pediatric patients between 5 and 15 years, who have DMA, treated in the southern metropolitan health service.Method: The sample of 250 patients with DMA was chosen from April to September of the year 2019, therefore, the data was extracted from the clinical records of the patients. The classification of the anomalies was carried out using the Bonn’s biogenetic method, modified by the University of Chile.Result: It was observed that the most frequent intermaxillary DMA of the sample is in the transverse direction and corresponds to the unilateral crossbite, on the other hand, the most frequent intramaxillary DMA is the alteration of dentoalveolar per large tooth. All intermaxillary DMA agreed to be more frequent at the age of 9 years.Conclusion: It was possible to define the frequency of the DMA in patients treated in the DSS, this being in the transverse direction, corresponding to unilateral crossbite. With the present study it is intended to make a contribution for future studies that use similar methodologies."
