This report describes the case of a 48–year–old female patient who wanted to replace her missing teeth. Edentulous arch span was long so a 4 unit fixed movable resin bonded fixed partial denture [RBFPD] was planed. Ceka preci vertix extracoronal attachment was used to provide non rigid connection between minor and major retainer. RBFDPs are a conservative tooth replacement option that requires minimum tooth preparation and retention by a resin cement to etched enamel. This case report highlights the use of modified non–rigid connector which allows relative movement between abutment teeth and therefore a reduced stress on the bonding interface of resin bonded prosthesis. It is proposed that the use of modified non–rigid connectors that allow independent movement between the abutment teeth during function is responsible for the long term clinical success of fixed–movable RBFDPs.
