Objective: to characterize the recurrent positions in third molars through the orthopantomographic analysis in patients of the Specialized Center in Dentistry "Dr. Mario Cerda e Hijos” in the city of Riobamba-Ecuador during the period 2015-2018. Material and Methods: an observational, descriptive, and cross-sectional study was carried out, in which orthopantomographies of patients were analyzed in this research. The studied population was made up of 172 radiographs, the position of 688 third molars was analyzed in patients aged between 15 to 50 years. Considering the technique, the data collected was the measurement using the negatoscope and the millimeter ruler, which were grouped according to the Winter and Pell and Gregory classifications. Results: 688 third molars were analyzed, the 48.1% was observed in vertical position, followed by the mesioangular position with 31.2%; class II with 43.3%, class I in 31.8% and class III with 18.8%; level B with 35.6%, level C with 34.9% and level A with 23.4%. Conclusion: The vertical position, class I and level C were more frequent in the maxillary third molars; while in the mandible they were the mesioangular position, class II, and level B.
