Inlay and Onlay are used when a restoration is too big for a filling but not so seriously damaged that it requires a crown. In general, if damage is minimal, Inlay is appropriate, while when more than half of a tooth is damaged (especially one or more of side of molar is destroyed), Onlay may be better.
An Inlay is similar to a filling as it lies inside the tips (cusp) of the biting surface of the tooth.
An Onlay restores a larger portion of the tooth and it usually covers one or more cusps in order to protect them from fractures.
What are the benefits of Inlay/Onlay?
- Inlay – Onlay have high durability and adhesive.
- Be an alternative solution to crowns or fillings.
- Inlay/Onlay by porcelain looks like natural tooth and keep color over time.
- No need to grind all cusps of tooth. This is one of the biggest benefits inlay gives you.
- Saving time and money with only 2 visits within 30-45 minutes/time
There are many materials used for Inlay and Onlay as porcelain, gold or composite resins that are bonded directly to the teeth. These materials are much stronger than traditional blended-metal fillings and can help prevent further decay or damage.
