Abstract:
Provided is a joining structure for processing which joins reliably and without misalignment a dental CAD/CAM block to be machined to a block holder for holding same onto a processing device. An engagement protrusion 11 is formed on a block-side joint surface 10e of a block 10 to be processed, and an engagement recess 17 is formed on a holder-side joint surface 14a of a block holder 13. An adhesive retaining space is formed therebetween. An adhesive is applied thereto, and the engagement protrusion 11 and the engagement recess 17 are engaged and joined. The engagement protrusion 11 formed on the block 10 to be processed is rectangular or substantially rectangular. If the engagement protrusion 11 extends from the front surface 10a towards the back surface 10b of the block 10 to be processed, the protrusion can removed from a mold 2 (shown in fig. 5) by moving the protrusion in the direction of the arrow P (shown in fig. 5).
