Statistical analysis determined the relationship between impacted maxillary and mandibular third molars and different skeletal facial types. The degree of third molar impaction was evaluated.Results: A total of 198 CBCTs from subjects were evaluated, with a mean age of 34.2 years. Archer II classification was found to be significantly associated with all skeletal profiles. The incidence of mesioangular impactions in lower third molar showed a notable increase in the brachyfacial group, which was statistically significant.Conclusion: In conclusion, this study demonstrates that different facial types are associated with the angulation of third molar impactions.Keywords: impacted, wisdom tooth, brachyfacial, dolichofacial, mesiofacial, retrospectiv
