What is the recommended depth for the inlay occlusal outline prepared with a tapered carbide bur?

The recommended depth for the occlusal outline of an inlay prepared with a tapered carbide bur is typically around 1.8 mm. This depth is ideal as it provides sufficient space for the restorative material while ensuring that the margins of the preparation are adequately defined for optimal bonding and retention of the restorative inlay.

Inlay preparations require a specific depth to accommodate the restorative material, maintain proper aesthetics, and ensure longevity of the restoration. Achieving a depth of approximately 1.8 mm balances the need for a solid foundation for the inlay while avoiding excessive reduction of healthy tooth structure, which could compromise the tooth’s integrity.

Restorative materials, especially those used in inlays, often require specific thicknesses to deliver optimal strength and durability; hence, adhering to this recommended depth helps in achieving an effective and long-lasting restoration.
