摘要:
Disclosed here is a dental resin sheet that is attached onto the surface of a tooth or the veneering crown to form the surface of the tooth or the crown. The dental resin sheet is constructed of a plurality of resin layers laminated into a uniform thickness, and the resin layers correspond to the layered structure of the tooth, one for the cervical, another for the dentin and another for the incisal. By laminating the layers of different shading in inclination with respect to the surface of the sheet, a shade of a tooth is achieved. A single elongated continuous sheet may be cut to a plurality of pieces of sheet each of which matches the configuration of a tooth. A single sheet may be configured to be shaped to the surface configuration of a tooth.
