Clinical Case: Simple and Beautiful – Dual-layer Technique in the Anterior Region

Using 3M™ Filtek™ Supreme Ultra Universal Restorative.

About the Case

When a restoration is needed in the upper anterior region of a patient with particularly high esthetic demands, many dental practitioners prefer indirect over direct restorative techniques. Reasons are a seemingly higher predictability and easier handling of the materials inside the mouth. However, it is possible to achieve beautiful results with little effort using direct composite materials as well – provided that several basic rules are respected.
