If your kitchen cabinet door or any custom cabinet door implodes for some reason or other DO NOT PANIC,DO NOT DESPAIR, DO NOT ACT IN HASTE!
The best thing you can do is carefully tape all the pieces in place and wait for me or some FIXIT type to arrive and carefully remove all the pieces and splinters to better assemble and reattach everything back together.
This door was reattached and reassembled with no sign of damage because the homeowner was careful not to add to the initial injury.
All the pieces fit together and complete recovery was the end result.
