Acrylic resins used for provisional prostheses should have satisfactory superficial characteristics in order to ensure gingival health and low bacterial attachment. The purpose of the present study was to evaluate the superficial roughness and contact angle after two types of polishing and the Vickers hardness of three acrylic resins (Duralay -G1, Dencrilay -G2, and Dencor -G3), all shade 66, indicated for provisional fixed prostheses.
