- Rochette bridge
A type of
dental prosthesispopular in the 1970's. A form of resin retained bridgethat 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
intaglioenabled better retention without the loss of strength inherent in perforation the retainer wing.
Nonetheless some Rochette bridges remain in service even today.
