Cone beam computed tomography for evaluation of impacted supernumerary teeth: a case report / Tomografía computarizada con haz de cono para evaluación de dientes supernumerarios impactados: reporte de caso

ABSTRACT

Supernumerary paramolars are the rare anomalies of the maxillofacial complex. These are more common in the maxilla than in the mandible. Supernumerary teeth are an infrequent developmental alteration that can appear in any area of the dental arches and which are often associated with several syndromes such as cleidocranial dysplasia or Gardner syndrome. Multiple supernumerary teeth in individuals with no other associated diseases or syndromes are very uncommon. Objective: To evaluate the value of cone-beam CT (CBCT) in the diagnosis and orientation of supernumerary teeth in the dental arches. Treatment After taking a cone beam computed tomograph (CBCT), surgical extraction was performed under local anaesthesia. Conclusion: The position of the supernumerary teeth is varied in the maxilla, and often causes permanent dentition complications. CBCT imaging yields accurate 3-dimensional pictures of supernumerary teeth, local dental and bony structures, which is helpful for diagnosis and orientation of supernumerary teeth. Cone beam computed tomography is crucial for exact localization, for treatment planning, and for the surgical approach in cases of multiple supernumerary teeth.
