Abstract
A dental block includes a block body having a one surface, and an engagement portion to be engaged with a dental implant fixture. The engagement portion has a bolt through hole and is formed in the one surface of the block body. The dental block further includes a ring-shaped abutment surface to be abutted against a top surface on the oral cavity inner side of the dental implant fixture. The ring-shaped abutment surface is positioned more inside the block body than the one surface and is formed from an end portion positioned at the most oral cavity inner side of the engagement portion to surround the end portion, and to be parallel to the one surface of the block body. The dental block further includes a diameter-enlarged portion having a tapered shape whose diameter increases from the ring-shaped abutment surface toward the one surface of the block body.
