When it comes to dental restorations, onlays offer an effective and aesthetically pleasing solution for damaged or decayed teeth. Onlays are an alternative to traditional dental fillings, providing a more extensive and durable restoration that covers a larger portion of the tooth's surface.
In this comprehensive guide, we will delve into the world of Onlay dental restorations, exploring their benefits, the procedure, materials used, aftercare, and more.
What is Onlays?
Onlays, also known as partial crowns, are custom-made dental restorations designed to repair teeth that have sustained moderate to extensive damage or decay. They are typically crafted from tooth-coloured materials such as porcelain, composite resin, or ceramic, ensuring seamless integration with the natural tooth structure.
Differences Between Onlays and Inlays
While both onlays and inlays serve the purpose of restoring damaged teeth, there is a fundamental difference between the two. Onlays are used when the restoration extends beyond the cusps (raised points) of the tooth, covering a larger surface area. Inlays, on the other hand, are used when the damage or decay is confined within the cusps.
When Are Onlays Used?
They are recommended in various situations, including:
- Large cavities or decay that is too extensive for traditional fillings.
