Abstract
Aligning a displaced maxillary canine into the dental arch is one of the most complicated problems in orthodontics. In cases of extremely high displacement, the tooth is frequently removed surgically. Because of the upper canines' significance to dental esthetics and functional occlusion, such a decision is a very serious one. The purpose of this report is to illustrate an interdisciplinary approach involving both orthodontic management and conservative tooth restoration. The case was treated through an orthodontic nonextraction fixed appliance mechanotherapy for successful alignment of buccally ectopic upper left canine followed by a conservative direct composite tooth buildup of peg lateral incisor associated with the upper left ectopic canine in a 16-year-old adolescent North Indian female. Posttreatment records demonstrated good alignment of the displaced tooth and restoration of normal anatomy of the peg shaped lateral incisor.
Highlights
An ectopic tooth is defined as a tooth that is following an abnormal eruption path whereas an impacted tooth is a tooth that is unable to erupt without assistance and is usually associated with an ectopic path of eruption
Since the permanent canines are the foundation of an esthetic smile and functional occlusion, their proper alignment into the arch becomes a priority for the orthodontist
The canine follows a mesial path until the crown reaches the distal aspect of the lateral incisor root
Summary
An ectopic tooth is defined as a tooth that is following an abnormal eruption path whereas an impacted tooth is a tooth that is unable to erupt without assistance and is usually associated with an ectopic path of eruption. The maxillary canine is present superior to the deciduous canine, angulated medially, with its crown lying distal and buccal to the lateral incisor. The canine follows a mesial path until the crown reaches the distal aspect of the lateral incisor root. The cause is genetic, and the condition has been called “primary tooth germ displacement,” meaning development of the tooth bud in the aberrant position or orientation, because of an abnormal genetic pattern [6]. Such cases are usually associated with reduced mesiodistal width of the lateral incisor and increased prevalence of anomalous lateral incisor [7, 8]. Shafer et al [13] enumerated the sequel for ectopic
