A guide to the orthodontic extrusion of traumatized permanent incisors in the mixed dentition

Extrusion of intruded maxillary incisors present the clinician with a great challenge, particularly in the mixed dentition. Due to their prominence and arch position, anterior teeth are the teeth most commonly involved in dental trauma.¹ Traumatic incisal intrusion accounts for 0.3–1.9% of traumas affecting the permanent dentition.² The complications after intrusive injury can be severe and include pulpal necrosis, inflammatory root resorption, replacement root resorption, ankylosis and loss of marginal bone support.³

Several methods have been suggested to treat an intruded maxillary incisor. Currently there is no definitive guideline on which method is most successful. The treatment mode selected should be based on the individual clinical situation and the best evidence available. The aim of this paper is to provide a guide for the orthodontic extrusion of maxillary incisors following intrusive luxation in the mixed dentition.
