Dental anomaly pattern and multiple ectopic teeth

Challenges of a two-phase orthodontic treatment of a mandibular lateral incisor-canine transposition and a maxillary palatally displaced canine: A case report

INTRODUCTION

The management of eruption disturbances in orthodontics may be challenging and requires a careful diagnosis and treatment planning. This case report discusses the challenges of a two-phase orthodontic treatment of a patient presenting with a dental eruption pattern anomaly.

PATIENT CONCERNS

A 10-year-old boy presented with no complaints for a routine orthodontic evaluation during the mixed dentition.

PRIMARY DIAGNOSES

The patient was diagnosed with a skeletal Class I malocclusion with unilateral posterior crossbite, incomplete mandibular lateral incisor-canine transposition and a unilateral maxillary ectopic canine.

INTERVENTIONS

Phase 1 started with rapid maxillary expansion to correct the maxillary constriction and the ectopic eruption of the right maxillary canine. In the mandibular arch, phase 1 included the extraction of the left primary lateral incisor and canine, alignment of the left permanent lateral incisor and orthodontic traction of the left permanent canine. The duration of phase 1 was 14 months. Phase 2 involved a comprehensive course of orthodontic treatment and started when the patient was aged 13 years. This phase lasted 18 months.

RESULTS

An adequate dental occlusion was obtained, and the treatment results were stable after an 18-month follow-up.

CONCLUSION

In this case, the early diagnosis of the dental anomalies was valuable as it allowed an early intervention to be undertaken, which resulted in overall treatment simplification and potentially minimised the adverse effects. This case report reinforces the importance of a careful follow-up during mixed dentition.

Dental anomaly patterns in mixed dentition: Illustrating the role of interceptive orthodontics in the management of mandibular lateral incisor-canine transpositions and palatally displaced maxillary canines

Dental anomalies of size, number, and position have been suggested to have a genetic background and frequently complicate the orthodontic treatment. Early intervention is a paramount step in managing patients with dental anomaly patterns (DAPs) to decrease the complexity of the case during the later stages of comprehensive orthodontic care. This case report highlights the importance of the detailed diagnosis in a case with several dental anomalies (mandibular lateral incisor-canine transposition, palatally displaced canines, small-sized maxillary lateral incisors and congenitally missing second premolar), utilizing interceptive orthodontic management in the mixed dentition stage in order to minimize the complexity and complications of comprehensive orthodontic care in the permanent dentition stage.
