A type of dental prosthesis popular in the 1970s invented by French Alain Rochette. 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 for the prosthesis.
They fell out of fashion as modern cenments and treatments of the retainer intaglio enabled better retention without the loss of strength inherent in perforation the retainer wing.
Nonetheless some Rochette bridges remain in service even today.
