The evolution of science has gradually embarked newer horizons of knowledge and application over a period of time. Failure of tooth eruption or impaction of tooth is a common problem affecting almost 20% of the population. Hence, treatment of impacted teeth has posed to be a challenge to the general practitioners and a number of other dental specialists, including Pedodontist, Periodontist, Oral and Maxillofacial Surgeon, and most of all, Orthodontists.The more convenient forms of auxiliaries to guide the eruption of impacted teeth are likely to improvise the preceding ones to make life easy.

To cope adequately with the problems of tooth impaction requires early diagnosis. It requires careful orthodontic surveillance of the developing dentition, because once impending tooth impaction is established the timing of surgical intervention is crucial. The cost benefit of such treatment is greatly influenced by the age of the patient.Treatment may involve surgical exposure and packing, it may involve orthodontic space opening, perhaps auto-transplantation, or even just an abnormally angulated prosthetic crown reconstruction.

This book attempts to highlight the development, prevalence, etiology, methods for diagnosis, complications and the treatment plan for impacted canine. The first section covers the introduction and literature review of canine impaction. The second section covers the development and prevalence of canine impaction. The third section covers various definitions, classification and etiological factors of impacted canine. The fourth section covers the various conditions, diagnosis and treatment planning of impacted canine. The fifth section describes the complications, retention and conclusion. The intention has been to propose ideas andprinciples that may be used to resolve even the most difficult impactions, employing orthodontic auxiliaries of many different types and designs.This book is beneficial for orthodontic practitioners, researchers, and post-graduate students.
