Composite Resin Restoration Assist · CDA

Why is incremental placement (layering) of composite resin recommended over placing it in a single bulk fill?

To make the overall procedure much faster
To reduce shrinkage stress and improve fit
To remove the need for a curing light entirely
To make later occlusal adjustment much easier

Show answer and explanation

Correct answer: To reduce shrinkage stress and improve fit

Layering in small increments reduces polymerization shrinkage stress and promotes better adaptation to cavity walls, reducing the risk of marginal gaps or micro-leakage.
