ONLAYS

Not all damaged teeth require full crowns. When a tooth has moderate structural damage but still retains sufficient healthy enamel, an onlay may provide a more conservative restorative option.

At Dental Creation Chiang Mai, onlays are designed with a focus on preserving natural tooth structure while restoring durability, function, and aesthetics.

What Is an Onlay?

An onlay is a custom restoration designed to repair damaged areas of a tooth while covering one or more cusps of the chewing surface.

Unlike full crowns, onlays preserve more natural tooth structure.

Onlays may be fabricated from:

  • Ceramic

  • Porcelain

  • Composite materials

Treatment recommendations depend on the condition and functional requirements of the tooth.
