Abstract: Provided is a machinable abutment-integrated prosthetic block. The machinable abutment-integrated prosthetic block is structured such that an abutment is integrated with a crown block made of a material requiring no heat treatment after undergoing machining processing. The abutment and the crown block are integrated by an adhesive layer containing a cured product of a polymerizable organic compound. Therefore, the prosthetic block which is an integrated form of the abutment and the crown block can be processed by machining processing such as CAD/CAM processing. Therefore, the prosthetic block can be processed, by machining processing, into artificial teeth to be used as temporary teeth or permanent teeth and does not require no additional heat treatment after undergoing the machining processing, thereby shortening a treatment time for implant restoration, resulting in a one-day prosthesis procedure.
