Inlays and Onlays
Inlays are similar to fillings but the entire work lies within the cusps (bumps) on the chewing surface of the tooth. Onlays are more extensive than inlays, covering one or more cusps. Onlays are sometimes called partial crowns.
Benefits of Dental Inlays and Onlays:
• Increase the strength of a tooth with respect to fillings
• Alternative to an crown when teeth damage is not extensive
• Porcelain inlays/onlays does not change color over time
• Gives better esthetic appearance compared amalgam fillings
Types of Inlays and Onlays
Inlays and onlays can be made of porcelain, gold, or composite resin. Porcelain inlays mimic enamel’s translucency and color, making them attractive choices for patients. Gold alloy inlays and onlays possess greater durability. The porcelain inlays and onlays used at our dental clinic include the IPS Empress II and IPS Empress Esthetics from Ivoclar Vivadent.
