A 50-year-old man sought treatment for missing maxillary second premolar and first molar teeth. Treatment planning software demonstrated that the mesiodistal space of the edentulous ridge was insufficient to receive 2 implants. A screw-retained, single-implant-supported zirconia fixed partial denture with a mesial cantilever extension was used to replace the 2 missing posterior teeth. This prosthesis, produced with a computer-aided design/computer-aided manufacturing workflow and consisting of monolithic zirconia with a connector cross-sectional area of 16 mm2, offered adequate resistance to chewing loads and still provided satisfactory esthetics at a 2-year follow-up examination.
