Lecture Description
Introduction : Ectopic teeth are frequently encountered in Orthodontic practice. These may be in variety of situations like impaction, transposition and malposition. Maxillary canine is the second most frequently impacted tooth in dental arch after 3rd molars. Impactions are common in females. Canine has the longest period of development, deepest area of development and most devious course to travel from its area of origin to erupt into proper occlusion. From crown calcification to eruption, it takes nearly twice as long as compared to other permanent teeth which makes it susceptible to much longer period of environmental influences both favourable and unfavourable. Both palatal and buccal impaction of canine have different etiology. Treatment options for all of above situations is based on its position and risk factors in individual case. Extraction of an impacted canine may be the best treatment alternative in certain circumstances, but because of the unique functional and esthetic characteristics of the permanent canine, clinicians prefer to bring an impacted canine into its proper position in the arch.
Discussion : A series of buccal, palatal and transposed canine cases have been discussed. Orthodontic management of such cases are very complex and require a carefully planned interdisciplinary approach. The surgical orthodontic treatment of impacted canines is aimed at bringing the tooth into its correct position in the dental arch without causing periodontal damage. Various forms of inter-arch and intra-arch mechanics have been developed for the eruption of impeded, impacted, transposed teeth.
Conclusion : The availability of newer materials with variable modulus and variable transition temperature has stimulated the development of various appliances designs with newer materials and configurations.
