This clinical report describes repairing and re-seating of a resin-bonded fixed partial denture placed in a patient suffering from periodontitis as well as leukemia. A mandibular seven-unit fixed partial denture (FPD) made of type IV gold alloy was seated in a 62-year-old male patient with an adhesive resin. Five years and two months after seating, two retainers detached probably due to labial inclination of the abutments. Two retainers were cut with a diamond rotary instrument, and the fractured composite veneer was repaired extraorally. The abutments were minimally reduced to remove the adhesive resin remnant. The repaired five-unit cantilever FPD was re-seated with a combination of the Metaltite primer and the Super-Bond Opaque resin. The FPD and abutments have been functioning satisfactorily for more than six months.
