The collum angle of Maxillary Central Incisors in different skeletal malocclusions – A Cephaometric study
Journal Title: International Journal of Applied Dental Sciences - Year 2016, Vol 2, Issue 3
Abstract
Variability in tooth morphology is an important consideration in the attainment of an aesthetic, functional and optimal occlusion of teeth. Crown to root angulation of maxillary central incisors may limit the degree to which the roots of these teeth can be torqued lingually when related to the maxillary lingual cortical plate of bone. The angulation of the root to the crown, particularly of the single rooted anterior teeth is known as Collum angle. It is the angle formed by the intersection of the long axis of the crown and root and it is measured using the lateral cephalogram.Gingival recession due to improper movement of tooth during orthodontic treatment may lead to cosmetic defects. The extent of recession is related to the bending angle. Therefore, understanding the crown-root angle in patients with different types of malocclusion is a critical issue. The present study was done to assess the collum angle in Urban population of Karnataka.
