Prosthodontic Management of Congenitally Missing and Peg-Shaped Maxillary Lateral Incisors: A Case Report.

This case report describes the prosthetic rehabilitation of a 24-year-old female patient who had aesthetic concerns due to implant failure in the right maxillary lateral incisor and peg-shaped left maxillary lateral incisor sites. The treatment plan included fabrication of a canine-supported zirconia cantilever prosthesis for the right incisor and a zirconia crown to restore the peg-shaped left incisor. A minimally invasive approach was employed, including abutment preparation, computer-aided design/computer-aided manufacturing (CAD/CAM) design, and precision milling of the zirconia restoration. The final restoration was cemented with resin cement. The result was the successful restoration of symmetry, functionality, and aesthetics in the maxillary anterior teeth, significantly improving the patient's smile and self-confidence.
