Inlays and onlays are types of indirect dental restorations used to repair damaged or decayed teeth. An inlay fits within the grooves of a tooth, restoring areas between the cusps without covering them. An onlay, sometimes called a partial crown, extends further to cover one or more cusps, providing greater protection. Both are custom-made from materials like porcelain, composite resin, or gold, and are bonded to the tooth for strength and durability. They are more conservative than full crowns, preserving natural tooth structure while restoring function, aesthetics, and long-term stability.
