Abstract
With the development of digital dentistry and computer-aided-design/computer-aided-manufacturing (CAD/CAM), implant placement became possible by analyzing the final prosthetic design and the anatomical structure of the alveolar bone. Before the development of guide stents using CAD/CAM, fixed bridges or cantilever bridges were used to repair missing teeth in places where implant placement was difficult due to poor alveolar bone shape. In the cantilever bridge, stress is applied to the pontic to remove the prosthesis, or the load is concentrated on the abutment and the prognosis of the abutment is poor. The patient in this case had implants placed only in the maxillary right central incisor (#11), and the prosthesis was restored with a cantilever zirconia porcelain bridge using the left central incisor (#21) as a pontic. Afterwards, she visited our hospital due to frequent prosthetic fallout and mobility. During intraoral examination, retention of the prosthesis was insufficient due to the short abutment length in #11. As a result of CBCT imaging and analysis, it was determined that implant placement in the #21 pontic was possible if a surgical guide was used. Therefore, we report that the patient’s discomfort was resolved through the restoration of the new prosthesis, and satisfactory results were obtained for both the patient and operator.
