Abstract

ABSTRACTDilaceration of the permanent tooth usually is a consequence of traumatic injuries to the primary teeth. Although it may appear anywhere in the long axis of the tooth, i.e., crown, cementoenamel junction, or root, most often the root is involved. However, crown dilaceration is a rare condition representing 3% of the total injuries. Maxillary incisors are more susceptible to such injury and affected tooth may either erupt buccally or lingually or remain impacted. Hitherto, the treatment options also differ as per the clinical scenario.This article proposes a novel technique of restoring esthetic function of the affected permanent maxillary lateral incisor with crown-root dilaceration while preserving the vitality of tooth.How to cite this article: Achary RC, Ravi GR.

Highlights

Traumatic injury to the primary tooth can result in various deformities in the permanent successor
Dilaceration is a relatively rare condition wherein only 3% among all kinds of traumatic injuries will result in crown dilacerations
Trauma that occurred during this age might have resulted in crown dilaceration with defective enamel formation leading to enamel hypoplasia at dilacerated area of the tooth

Summary

INTRODUCTION

Traumatic injury to the primary tooth can result in various deformities in the permanent successor. The maxillary left lateral incisor exhibited crown dilacerations affecting incisal and middle third of the crown with an acute bend palatally. Intraoral periapical radiograph (Fig. 1C) showed maxillary left lateral incisor with crown dilaceration affecting incisal and middle third of the crown directed palatally. Labial movement was achieved by modified Hawley’s appliance with double cantilever spring in relation to #22 and posterior bite plane During this phase of treatment, the path of insertion and removal of Hawley’s appliance and activation of double cantilever spring was found to be difficult due to deflection of crown on the palatal side resulting in an undercut on palatal portion of the crown. The final restoration was finished and polished in subsequent session with fine and extrafine disk (Dentsply) and followed up for 18 months (Figs 5 and 6)
