Decoronation of ankylosed teeth: An Overview

Abstract

Severe traumatic dental injuries to permanent incisor teeth often result in replacement resorption following significant damage to the periodontal ligament. This leads to ankylosis and subsequent infra-occlusion of the traumatized tooth in a growing paediatric patient. Extraction of these teeth can lead to vertical bony defects that complicate restorative management of the edentulous space. Decoronation is a technique employed to preserve bone in the alveolar crest in an attempt to reduce these defects. CPD/Clinical Relevance: This paper aims to remind readers of the processes of replacement resorption and ankylosis and introduces the use of decoronation for such teeth.
