What’s the worst feeling in the world? I agree, that moment when you go to check the occlusion on your Class II amalgam and the patient chomps down breaking the marginal ridge and box. It *literally* sends shivers down my spine. Next time you’re doing a big Class II amalgam or build-up, before removing the tofflemire and rubber dam, take your IPC (Interproximal Carver if ya don’t know) and completely level the ridge to the same height as the neighboring teeth. Sure it might mean extra work to re-carve your anatomy, but that’s more manageable than redoing the entire restoration.
