Cabinets in my kitchen have hidden hinges on inside of doors (fairly new modern cabinets--hinge says "salice"). One of these pulled out of the holes in which it was installed in the side of the cabinet. Looks like it was installed whole (screws don't unscrew from hinge, but are threaded through a connecting plastic plate and into metal sockets with threads on the outside). Anyone have ideas how I can repair this? The door is unusable as is. thanks.

Here's a link to the hinge manufacturer

The hinge is fully adjustable and separates from the mounting plate.......Sounds like yours are fastened into particle board.......

The screw inserts can be glued/epoxied back into the existing oversized holes in the board .....and when dry screw the mount to the particle board and the hinge to the mount............
