What is the minimum axial reduction required for a crown?

Explanation:
The minimum axial reduction required for a crown is typically 1.5mm. This amount of reduction is vital to ensure adequate space for the crown material and to provide both retention and resistance form to the restoration. Insufficient axial reduction can result in a crown that lacks the necessary strength and stability, leading to potential failures such as dislodgement or inadequate fit. Furthermore, having this minimum reduction helps in achieving proper contours for both aesthetic and functional outcomes. Certain material requirements may necessitate even greater reduction, but 1.5mm serves as a general guideline for most crown procedures.
