Summary: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). 本发明提供的加工用接合结构，能够将被机械加工的牙科用CAD/CAM块和用于将牙科用CAD/CAM块保持在加工装置上的块
