A Class IV restoration involves which tooth feature?

Understanding Class IV restorations: they involve the proximal surface of an anterior tooth and extend to include the incisal edge. The incisal edge is the biting edge of the front teeth, and when a restoration reaches that edge, both the proximal area and the incisal angle must be rebuilt for strength and aesthetics. This sets Class IV apart from restorations that only affect the proximal surface of an anterior tooth without touching the incisal edge. Since posterior teeth don’t have an incisal edge, Class IV is specific to anterior teeth. So the best description is a restoration on the proximal surface of an anterior tooth that includes the incisal edge.
