Comparative tomographic study of the maxillary central incisor collum angle between Class I, Class II, division 1 and 2 patients

Abstract

Our findings suggest that Class II, division 2 individuals demonstrate accentuated lingual inclination of the maxillary central incisor crown compared to the other types of malocclusion studied here. Such morphological feature indicates the need for better tooth movement planning, especially in regard to root palatal torqueing of the maxillary central incisors.
