Inlay and onlay restorations are advanced restorative dental treatments used in large cavities where conventional composite fillings are insufficient. At Dentme Oral and Dental Health Clinic in Gaziemir, inlay–onlay restorations are custom-made to preserve the natural tooth structure while providing superior durability and aesthetics.
What Is Inlay & Onlay Restoration?
Inlay and onlay restorations are indirect fillings fabricated in a dental laboratory after removing decayed tooth structure. They are usually made of porcelain or zirconia and bonded precisely to the tooth.
Difference Between Inlay and Onlay
- Inlay: Restores smaller cavities within the tooth.
- Onlay: Covers a larger area including the cusps of the tooth.
Difference from Composite Fillings
Composite fillings may shrink over time in large cavities. Inlay–onlay restorations are fabricated outside the mouth, offering excellent marginal fit and long-term stability.
Treatment Procedure
- Local anesthesia is applied
- Decay is removed
- Impression is taken and sent to the lab
- The restoration is bonded with high-strength adhesive
Advantages of Inlay & Onlay Restorations
