Corrective Maintenance - ususally you perform this type of maintenance work to fix something that does not/no longer works.

Preventive Maintenance - you perform this type of repair to prevent further damage which will be more costly to repair down the road.

Example - regular teeth cleaning is a preventive maintenance while tooth removal, root channal, framing (箍牙) are corrective maintenance

Checking tire pressure and refill air as needed is preventive maintenance while patching flat tire is a corrective maintenance.

Overlay street with asphalt paving is preventive maintenance while remova and reconstruct roadbed is corrective maintenance.

Buying red roses on regular basis is a preventive maintenance (for the relationship). When time comes that you need to buy yellow roses to say (I am sorry), that becomes corrective maintenance.......
