"My CPU board is a CSPPC with a CVPPC. If no other pressure is made to the board is it OK that it is only supported by the slot, or will it damage the board over time?"
you can bet on with the CSPPC PCB so bent!
Take out the mobo again and try to alling the mobo/CSPPC the better you can (it sound weird thats the CPU slot beeing bent)
