This clinical report describes the repair of a fixed partial denture (FPD) with fracture of porcelain using an overcasting. Porcelain veneer of a maxillary six-unit FPD made of cobalt-chromium was fractured. Veneered areas were cut with a diamond rotary instrument, and an overcasting restoration was made with gold alloy and feldspathic porcelain. The two-unit overcasting restoration was seated with a combination of the Alloy Primer conditioning agent and Super-Bond adhesive resin. The repaired FPD, overcasting, and abutments have been functioning satisfactorily for more than two years and two months. (Int Chin J Dent 2006; 6: 17-20.)
