Inlay and onlay
The restoration is dubbed an "inlay" when the material is bonded within the center of a tooth. Conversely, the restoration is dubbed an "onlay" when the extent of the damage requires inclusion of one or more cusps of the tooth or full coverage of the biting surface.
Inlays and Onlays: The Benefits of the Conservative Approach
Superior Fit: Inlays and onlays offer a conservative preparation that preserves as much healthy tooth as possible. They are a great choice if you have minimal to moderate tooth decay that extends into a flossing area, offering an excellent alternative to full coverage crowns.
Tooth Color: Boasting esthetic longevity, inlays and onlays are not likely to discolor over time as tooth-colored resin fillings often do.
Tooth Structure Safeguard: Inlays and onlays preserve the maximum amount of healthy tooth structure while restoring decayed or damaged areas, helping to ensure functional longevity.
Easy Tooth Cleaning: Because the fit is tailored at all edges and the preparation minimal, your tooth can be easier to clean than it would be with full coverage restorative alternatives such as a dental crown. Composite fillings can shrink during the curing process, whereas prefabricated porcelain or gold inlays and onlays will not (ensuring a precise fit).
Tight Space Fulfillments: If you have a cavity between your teeth, consider an inlay rather than a direct composite filling. Inlays are better at sealing teeth to keep out bacteria; they are easy to clean, will not stain and offer exceptional longevity.
Strength and Stability: Inlays and onlays are extremely stable restorative solutions for the treatment of decay. The superior fit and durable material make inlays and onlays a stable choice that can actually strengthen a damaged tooth.
Weak Tooth Protector: An onlay can protect the weak areas of the tooth. The procedure does not require the complete reshaping of the tooth.
