What is the primary goal when preparing a tooth for a crown?

The primary goal when preparing a tooth for a crown involves achieving minimal taper. This is essential for ensuring that the crown will have a secure fit and proper retention on the tooth structure. A minimal taper allows for a more precise adaptation of the crown to the tooth preparation, which is crucial to prevent dislodgment and to promote a lasting bond between the crown and the tooth.

When the taper is minimal, it optimizes the crown's resistance to displacement forces, providing greater stability in function. A well-prepared tooth with minimal taper also minimizes the risk of damaging adjacent teeth and supports the maintenance of the structural integrity of the tooth being crowned.

Although factors like adequate thickness and uniform surface texture are important for the crown's aesthetic and functional qualities, the taper's significance directly influences the retention and overall success of the crown long-term.
