A resin-retained bridge (also known as resin-bonded-bridge or resin-bonded fixed dental prosthesis (RBFDP)) is a bridge (a fixed dental prosthesis) replacing a missing tooth that relies for its retention on a composite resin cement.
They are commonly used to definitively cement indirect restorations, especially resin bonded bridges and ceramic or indirect composite restorations, to the tooth tissue. They are usually used in conjunction with a bonding agent as they have no ability to bond to the tooth, although there are some products that can be applied directly to the ...
Post crowns have been shown in some studies to have a higher failure rate. [3] For resin bonded bridges abutment teeth should ideally be unrestored and have enough enamel to support the metal wing retainer. Additionally there must be sufficient space to accommodate the minimum connector width of 0.7mm and 2mm connector height.
Resin cements are widely selected for luting non-metallic restorations, resin bonded bridges, ceramic crowns and porcelain veneers. [26] They are available in a different number of shades, viscosities and aesthetic try-in pastes. These cements are also an option for use with ceramic and resin composite inlays and onlays. [26]
A bridge is used to span, or bridge, an edentulous area (space where teeth are missing), usually by connecting to fixed restorations on adjacent teeth. The teeth used to support the bridge are called abutments. A bridge may also refer to a single-piece multiple-unit fixed partial denture (numerous single-unit crowns either cast or fused together).
A Rochette bridge is a type of dental prosthesis popular in the 1970s, [citation needed] and described by Alain Rochette in 1973 [1] as a form of resin retained bridge that relied on countersunk holes perforating the metal abutment wing. These would be filled with composite cement on seating the restoration, providing macromechanical retention ...

Research has reflected a survival rate of 80% over a period of 6 years or longer, [88] and that cantilever resin-bonded bridges are at least as good as conventional fixed-fixed bridges. Restoring teeth with this method can only be done after orthodontic treatment and will need an element of retention to ensure that tooth contacts are not misplaced.
