Maxillary Right Lateral Incisor Agenesis and Left Peg Lateral Incisor- A Long Term Follow-up

Abstract

Missing maxillary lateral incisor is commonly found in orthodontic daily practice. To close the space using intermaxillary elastics with sliding jig is successful alternative. This case report described a case of a young adult 18-year-old patient with missing maxillary right lateral incisor, with a permanent canine in its position and a retained deciduous canine. In addition, the patient presented with a peg shaped left lateral incisor. To solve the problem, the teeth in the maxillary right quadrant were moved medially towards the midline. A multidisciplinary approach involving periodontic-restorative procedure were proposed, but just orthodontic alignment and leveling were performed with minor canine reshaping and no reshaping in the peg-shaped left lateral incisor. At the 15.8 years follow-up consultation the right canine and left lateral incisor were reshaped, improving the outcome. In a long term perspective, radiographic images show no sign of bone loss or root resorption and the results continue to be stable, with maintenance of the clinical results achieved.
