Dental inlays and onlays are indirect restorations used to repair posterior teeth that have mild to moderate decay or damage. Fabricated outside of the mouth, typically from materials like porcelain, gold, or composite resin, they are then cemented or bonded to the tooth. An inlay fits within the cusps (the pointed parts) of the tooth, while an onlay extends to cover one or more cusps, offering more extensive coverage.
These restorative options offer several advantages over traditional fillings. They are more durable and long-lasting, often providing a better fit and seal, which helps to prevent recurrent decay. Furthermore, the materials used can be matched to the natural tooth color, resulting in a more aesthetically pleasing outcome. Historically, gold was the primary material, but advancements in dental materials science have led to the widespread use of tooth-colored options.
