As technology progresses, the basic desires and expectations of humans are also increasing day by day. Esthetics is becoming the prime concern of patients even more than treatment. Here comes the role of esthetic restorations for anterior teeth as well as posterior teeth. An inlay or onlay is a more conservative and long-lasting way of restoring the tooth than metal filling, composite, and even a crown. Inlays are intracoronal restoration which may cap one or more, but not all of the cusps, and onlays are also a type of intracoronal restoration which cap all of the cusps of tooth. Most indirect restorations are made on a replica of the prepared tooth in a dental laboratory by a trained technician. Ceramic inlays and onlays have become popular not only because of patient demand for esthetic, durable restorative materials, but also because of recent improvements in materials, fabrication techniques, and bonding systems. The traditional fillings reduce the tooth strength by up to 50% whereas inlay or onlay made up of high-strength porcelain or ceramic can actually increase tooth strength up to 75% and lasting 10 to 30 years. Therefore, maximum amount of tooth structure is conserved with the help of inlay and onlay as compared with crown. And the strength provided by tooth itself is much higher than any restorative material, the best way to maintain and improve the strength of tooth is preservation of the tooth
