INLAYS AND ONLAYS
Inlays and onlays are indirect dental restorations, which means they are made outside of your mouth in a laboratory. An inlay or onlay is typically used when a cavity is too large for a simple filling.
A dental inlay is made of a solid, custom-formed material. Depending on the cavity size and depth, inlays are either cast into shape with gold or milled into shape with porcelain.
An inlay is molded to fit into the grooves of your tooth. It does not extend over the cusps of the tooth.
Similar to inlays, dental onlays are made of a solid, custom-made material. An onlay is larger than an inlay but smaller than a dental crown. It is used to fill a larger cavity that extend over the cusps of a tooth.
The process of making inlays and onlays are similar to crowns but they are the more conservative options to full contour crowns. For more information contact us 9748038280/7890008331
Inlays and onlays can be made of gold, composite, or ceramic materials:
In the past, gold was the material of choice for inlays and onlays because of its strength. Since gold is extremely durable, it protects weakened teeth cusps caused by cavities and trauma.
Today, with the introduction of tooth-colored restorations, gold dental restorations are less common.
Gold inlays are typically used if a cavity filling repeatedly fractures. Composite or ceramic (porcelain) inlays may be chosen for aesthetic reasons, but they are more prone to damage.
Some dentists recommend opting for gold inlays or onlays in areas of the mouth where appearance is not important, such as the back molars.
- Very strong and malleable
- Extremely low chance of fracture
- Does not blend in with your natural tooth color
- More expensive than other restorations
Ceramic inlays and onlays are made of porcelain. In dentistry, porcelain is used to create tooth-colored restorations that mimic the color, shape, and function of natural teeth.
- Strong and durable material
- Less prone to fracture than traditional fillings
- Blends in with the color of your natural teeth
- More fragile than gold restorations
- Despite its strength, ceramic is a rigid material with an increased risk of fracture
Composite inlays and onlays are used to fill cavities that are too large for traditional fillings. They are an alternative to gold or ceramic restorations and still perform the same functions.
- Stronger and less prone to fracture than traditional dental fillings
- Tooth-colored, blends in with your natural teeth
- Weaker than gold restorations
- Less malleable than gold or porcelain restorations
- Not stain-resistant
