This article reports a resin-bonded fixed partial denture (RB-FPD) applied to a diabetic. Before seating the RB-FPD, a removable partial denture was used for about one year after extraction of a second molar. The RB-FPD framework was cast from silver-palladium-copper-gold alloy (Castwell M.C. 12), and the surface to be bonded was air-abraded with alumina. The RB-FPD was then treated with a metal priming agent (V-Primer), and bonded with an adhesive resin (Super Bond Opaque). After an observation period of six years and six months, the FPD was functioning satisfactorily. The materials and procedures reported here are applicable as an option for a prosthodontic treatment for medically compromised patients.(Int Chin J Dent 2009; 9: 15-18.)

Key Words: adhesive, alloy, primer, resin-bonded fixed partial denture, removable denture.
