Evaluation for the position of impacted maxillary canines from an orthodontic viewpoint
Impacted maxillary canines are a common dental eruption abnormality that occurs in between 1% to 13% of the population. We conducted a study of 70 patients between 7 to 14 years of age who visited the Orthodontic Department of Osaka Dental University Hospital between 2009 and 2018. They had Hellman...

Summary: | Impacted maxillary canines are a common dental eruption abnormality that occurs in between 1% to 13% of the population. We conducted a study of 70 patients between 7 to 14 years of age who visited the Orthodontic Department of Osaka Dental University Hospital between 2009 and 2018. They had Hellman dental developmental stage IIIB and impacted maxillary canines based on the Sector classification according to Lindauer et al.,1 the classification of McSherry,2 and Pitt et al.3 Among them 42.9%, 13.3%, 9.5% and 34.3% had a Sector classification of I, II, III and IV, respectively. By the classification of McSherry and Pitt et al., in division ①, ①-1 was the most common, in division ②, ②-2 was the most common, in division ③, ③-2 was the most common, and in division ④, ④-2 was the most common. Determining the correlation between the Sector classification, the classification of McSherry and Pitt et al., as well as the growth and development of the maxillofacial complex and bone age (cervical vertebral maturation), should aid in the early diagnosis of impacted maxillary canines and aid in the treatment of impacted teeth during orthodontic treatment.
