Introduction and objective: The Impaction of third molars is a very common clinical situation in the world population; Pell & Gregory have suggested a classification for impaction based on horizontal and vertical position. To identify the frequency of impacted third molar positions in patients treated at the CES-Sabaneta clinic between the years 2006-2016. Materials and methods: According to the oral surgery service database, two examiners during 3 months reviewed 626 clinical histories in patients between 17 and 28 years of ages who had complete dental formula, with panoramic radiography and who were remitted for reasons orthodontic, restorative or surgical. Results: A total of 515 third molars were evaluated, the third most impacted molar was 28 (25.6%), followed by 18 (25.4%), 48 with 24.6% and 38 with 24.2%. %. The female gender prevailed with 58.6%. The most impacted tooth was 28 (87.8%). At the vertical level, position C was the most impacted, while in men the most impacted tooth is 18 with a 79.7. %, position B was the most impacted and at the horizontal level class II was the most common in both sex. Conclusions: At the vertical level, position B was the most frequent in the third molars of the female gender, however in the male gender there was a variation, in the maxillary the position C predominated; A horizontal level class II was the most frequent positions in both sex.
