This clinical report describes a resin-bonded fixed partial denture (RB-FPD) seated with the aim of replacing a congenitally missing lateral incisor as well as for permanent retention after minor teeth movement. A RB-FPD framework was cast from silver-palladium-copper-gold alloy (Castwell M.C. 12), and the pontic was veneered with indirect composite material. The RB-FPD was treated with a metal priming agent (Alloy Primer), and bonded with a composite luting agent (Panavia Fluoro Cement). After an observation period of seven years and six months, the FPD was functioning satisfactorily without periodontal rebound. The materials and technique reported here are applicable as an option for fixed prosthodontic treatment after closing anterior open spaces in adolescent patients. (Int Chin J Dent 2008; 8: 29-32.)
