The invention relates to a resin infiltration zero-dimensional/one-dimensional porous ceramic composite material for dental restoration, and a preparation method thereof, and belongs to the field of dental restoration materials. According to the present invention, a dental restoration material with performances well matched with natural human teeth is designed and prepared; the guiding ideology isbased on the principle of multi-scale and multi-dimensional reinforcement and toughening; a porous ceramic preform is prepared by mixing preparing zero-dimensional ceramic powder and one-dimensionalceramic nano-wires/fibers, and a dental restoration material having a good resin and ceramic double-interpenetrating cross-linking network structure, capable of being using for CAD/CAM technology cutting and having mechanical properties matched with natural teeth and excellent cutability is prepared by using a vacuum-assisted resin infiltration technology and a thermal curing technology; and the bridging effect of the one-dimensional nanometer filler can effectively prevent the occurrence and development of cracks so as to improve the mechanical properties of the restored body and can effectively reduce the wear loss of the ceramic powder.
