3/4 Gold Crown Prep. Upper 1st Premolar

Three-quarter crowns were originally devised to preserve the buccal enamel of a tooth that required a crown, for aesthetic purposes. The advent of ceramics in dentistry has largely solved the aesthetic crown problem, but they are still useful as a way to conserve tooth tissue.
They remain one of the most technically challenging procedures in operative dentistry.
